What Type of Welder is Best for Exhaust?

Welding exhaust pipes is not as easy as other welding jobs. Generally, exhaust pipes can be as thin as 0.028” and are prone to burning. Hence, proper caution should be taken as well as the correct welding technique. 

As you know, there are different welding techniques exits. Not all types of welder can be a good choice for welding exhaust pipes. Some welders will allow you to get the job done quickly without burning – for example, MIG welders. 

Before you decide on any welder, you must know in which welder you should invest. Below we will discuss each welding technique with its pros and cons. So, you can make an informed purchase.

How to Weld Exhaust Pipe with Stick Welding?

There is a saying that stick welding is not suitable for repairing or welding exhaust pipes. But, you’ll be shocked to know that it is possible to repair the exhaust pipe with a stick welder. 

Be ready to think outside the box. It requires a bit of ingenuity to repair exhaust pipes with stick welders. However, the essential part understands the kind of rod to use. 

The 6011 is the best choice for this job due to its accurate welds on soft surfaces. Make sure to get the thinnest 6011 rod – a 1/16 rod will be a perfect choice. Use the rod with spot welding technique before welding around the tubing.

Cleaning is essential before welding though stick welding is hardly affected by paint, rust, and dirt. It is necessary to avoid slag. 

Benefits of Using Sick Welding for repairing Exhaust Pipe

  • Stick welding can be done in all weather.
  • You can weld an exhaust pipe anywhere inside the workshop or outdoors.
  • Stick welding is not sensitive to dirt, paint, and rust
  • The process is inexpensive and easy to use

Drawbacks of Using Stick Welding for Exhaust Pipe

  • Stick welding can lead to slag, which produces leak, if not done properly
  • A lot of electrodes is used as a few inches can be welded at a time

Safety Tips

  • Make sure to wear necessary protective equipment, including gloves, welding mask, etc.
  • Maintain a low amperage range to avoid overheating your welder and burning the pipes
  • Do not weld the exhaust pipe when attached to the car. The produced sparks can lead to an explosion.
  • Be sure to weld in a well-ventilated room as stick welding creates heavy fumes.

How to Weld Exhaust Pipe with Flux Core Welding?

Similar to stick welding, flux core welding is also not highly recommended for repairing exhaust pipes. You can still repair the exhaust pipe with a glassless flux core welder. Knowing a few things will get the job done. 

First of all, you need to clean the tubing due to the flux in the electrodes. It is essential to reduce the number of splatters. Next, you need to adjust the amperage settings. Reduce the amperage since flux-core welding produces a hotter arc. 

Then, decrease the speed of the wire feed a bit. It ensures that you don’t burn the tubing because of the hotter arc. 

Benefits of Using Flux-core Welding for repairing Exhaust Pipe

  • Flux-core welding provides better penetration than MIG electrodes
  • You can do it outside without needing a separate gas shielding tank
  • Flux-core electrodes are less expensive than MIG wires
  • The wire is fed continuously, so there is no need of changing the electrodes
  • The overall cost is less than MIG and TIG welding

Drawbacks of Using Flux-core Welding for Exhaust Pipe

  • It requires a higher level of precision; otherwise, it can burn through thin metals.
  • The process produces more splatter

Safety Tips

  • Make sure to wear goggles to protect eyes from heat and UV rays
  • Protect your feet from sparks by wearing closed-toe shoes
  • Wear long pants to protect your legs
  • Wear gloves with forearms to protect your skin as the arc tends to become hotter

How to Weld Exhaust Pipe with MIG Welding?

MIG welding offers the best way to weld exhaust pipes. It does an excellent job in fixing exhaust pipes than a stick and flux-core welding. Like other MIG welding tasks, clean the base metal at first. Make sure the exhaust tubing is free of rust and dust. 

Use a metal brush to clean the exhaust tubing and thus uncover the base metal. It is advised to use a combination of argon and carbon dioxide for MIG welding. Moreover, use a medium amperage range to avoid burning the soft surface of the exhaust pipe. 

Benefits of Using MIG Welding for repairing Exhaust Pipe

  • Since there is no flux used when MIG welding, so you don’t have to worry about slag.
  • MIG welding can be achieved in several ways, including full and semi-automatic techniques
  • MIG welding is faster and better than a stick and flux-core welding
  • Due to the versatile nature, you can do MIG weld on different kinds of metals, including alloys

Drawbacks of Using MIG Welding for Exhaust Pipe

  • MIG welding requires additional shielding gas tank
  • It is not suitable to use MIG welding outside or in windy weather
  • The process is somewhat expensive

Safety Tips

  • As MIG welding tends to produce a hotter arc, make sure to wear fireproof welding gloves.
  • Protect your feet from sparks with closed-toe shoes
  • There will be fumes and harmful UV rays while MIG welding. So, wear a protective mask to protect your face

How to Weld Exhaust Pipe with TIG Welding?

TIG welding is excellent for thin welding sheets of metals. This technique excels at welding exhaust pipes as it is made from sensitive alloys like stainless steel. However, you need to be extra careful while TIG welding the exhaust pipe.

Note that TIG welding has no tolerance for oils, paints, dirt, and rust. That’s why it is essential to clean the base surface at first. You can use acetone raced lag to remove oils that might be left due to the thick lube oils used on exhaust pipes. 

In this process, the ideal tungsten rod is a 3/32-inch rod. Also, the filler rod should be small in size. You need to be more careful with your heat output due to the exhaust tube’s delicate nature. 

Use a foot pedal to adjust the overall heat output based on the metal’s thickness. TIG welding is meant for thin metals and surfaces. Thus, we highly recommend using TIG welding for exhaust pipes. 

Benefits of Using TIG Welding for Repairing Exhaust Pipe

  • The most suited welding process for exhaust pipe or other thin metal sheets
  • Controlling heat output is easier with the foot pedal, which is necessary to avoid burning through the pipe.
  • TIG welding is clean and free of any slag making the finished weld aesthetically appealing
  • With the lower heat output, it is best for welding thin metal like the exhaust pipe.
  • TIG welding is the most versatile process which allows welding a range of metal and alloys

Drawbacks of Using TIG Welding for Exhaust Pipe

  • TIG welding is time consuming compared to other welding processes
  • High initial cost makes the process a bit expensive

How to Choose the Best Welder for Exhaust Pipe? (Detailed Buyers Guide)

The use of welding machines is increasing among the do-it-yourselfers. With a portable and compact welder, you can do all your DIY repair jobs. But, when it comes to repairing exhaust pipes, not all welders do this job well.

So, how to know which welder is best suited for repairing your exhaust pipe? Knowing a few factors will help you understand which welder can handle it better. You can check the following features into the welders in the marketplace. 


Welding is a process where pieces are fused together using heat. An electrical spark or a gaseous flame generates the heat. To do all these, a welder needs enough power. But, things are different when it comes to the power of a welder. 

  • Power Output

The power output decides the type of work you can do with it. Also, it defines how frequently you’ll be doing it. If you are welding thicker metals, you’ll need higher power output. But, the same output is not suggested for welding thin gauge metal.

The exhaust pipe includes a varying thickness. So, a welder should have a balanced power output to weld both thin and thicker metal. The ideal power output of a welder is between 10amps and 140amps. Here, 10amps welder can handle thin gauge metal, while 140amps is sufficient for a thicker sheet of metal. 

  • Power Input

As a welder needs a power source to operate, you need a welder that requires little but gives more. If the input power is less than the output power, it helps reduce the electricity cost. Minimal power is enough for the welding exhaust pipe. 

A welder with a power input of 115V to 120V should be enough. Generally, a 140amps unit requires 120V power input. However, it is wise to choose a welder that has dual voltage input. Some welders can operate with both 115V and 230V power outlets. 

Duty Cycle

The duty cycle is what you cannot ignore while buying a welder. It denotes the amount of time a welder can perform without overheating in 10-minutes. As you know, the duty cycle is expressed in percentage. Some welder has a duty cycle of 40% at 100A. 

Those units can operate continuously for 4-minutes and then require 6-minute to rest. Most welders have longer duty cycles as they are suited for heavy-duty works. It meant they could use longer without requiring a break.  

Wire Feed Speed

The wire feed speed is the speed at which welding wire is fed from the gun. It plays an essential role in the quality of the finished weld. If the speed is too low, the wire will disappear the time it touched the metal. 

It results in an uneven and messy welding finish. Conversely, if the speed is too high, there will be nothing but splatter everywhere. You’ll be left with too much wire at the end. 

Hence, the option is to choose a welder with adjustable wire feed speed. The speed will be adjusted automatically depending on the power. 


As mentioned earlier, welding has become a do-it-yourself thing now. Most people with little welding knowledge prefer having a portable welder at home. So, they can take along the welder wherever they want.

The weight of the welding machine varies in height from 10-100 pounds based on the size. If you choose a larger unit, you may get high power output, but it is heavier as well. 

Also, some smaller-sized welders deliver more than the larger ones. So, which one you need? Ask yourself if you have enough space at home? Do you need to shift it from time to time? If not, then consider buying a smaller welder. 

Safety Features

It is always best to have enough safety features in the welder. So, you can stay safe from any undesirable accident. Below are some safety features available in the best type of welder for exhaust.

  • Thermal Overload Protection – this feature helps to shut the machine automatically towards the end of the duty cycle. Thus, it prevents overheating and prolongs the welder’s life. 
  • Built-in Contactor – This feature helps to cool down the wire instantly till you pull the trigger. 


It is worth considering the warranty of the welder. The best welder for exhaust system should have at least one year to 3 or 5 years warranty. Since welder comes at a great price, it is better to go with a clear return policy. So, you can replace or return the machine if there is an issue. 

How to Weld Exhaust Pipes? 

First thing first, you’ll need some specific tools to weld exhaust pipes. Here is the list of equipment you need;

  • A good-quality, functional welder
  • Hacksaw or circular chainsaw to cut the exhaust tubing
  • Clamps for holding the tubing together
  • Grinder for crushing the tubing’s joints
  • Welding mask and gloves

With the above tools at hand, follow the steps below to weld the exhaust pipe.

Step-1: Cut the Pipe

Cutting the exhaust pipe is the essential step of this process. The way you cut influences the finished appearance of the pipe. Hence, you need to cut the pipe with great precision. 

At first, mark the pipe where you need to cut. Then proceed to cut using a hacksaw as neatly as possible. Make sure to cut straight for a more professional look. After cutting the pipe, remove the flaws on edge using a grinder.  

The grinder also removes dirt, paint, or rusts on the surface and exposes the base metal. Try to make it finer for a clean, impurity-free weld. 

Step-2: Clamp the Pieces Together

Once the tubing pieces are cleaned and ready, it’s time to clamp the pieces together. You’ll need a C-clamp for this job. It comes in handy to join the tubing pieces together before you start welding. Note that you need to clamp it in a way you want. If any adjustment is required, do it right away.

Step-3: Use Spot Welding

Since the exhaust tube is thin, it is advisable to use spot welds. Spot welding is doing three to five welds around the circumference of the exhaust tube. Due to the high heat produced during welding, it prevents the tubing from warping.  

If there are gaps on the tubes opposite side, you can bend them into place easily. Spot welds still cause clamped pipes to hold together.

Step-4: Finish the Weld

Finally, after spot welding, it’s time to weld the remaining gaps of the exhaust tube. It is advisable to weld around the circumference of the tubing to avoid leaks. Welding over spot welds makes your finished weld solid and durable. 


How to fix an exhaust leak without welding?

A leak in the exhaust pipe may result in poor maintenance cost and fuel economy. If you want to avoid the cost of paying for a welder, there are smart ways to do it. You can fix your exhaust pipe;

  • By sealing the leak (using epoxy bond and tapes)
  • With the tailpipe (using silencer)
  • With exhaust cement
  • Wrap it with exhaust bandages

Can you weld an exhaust pipe?

Absolutely, you can. In fact, it is the most precise way to repair your damaged exhaust system. You can use almost any type of welding technique to do this job. Still, MIG welding is most-preferred for the welding exhaust pipe. However, you need to be careful with the amperage of the welder. Make sure you get the right welding machine to the weld exhaust pipe. Also, you need to careful with the power that the welder uses.

Can you weld an exhaust manifold?

Yes, you can. Welding a damaged exhaust manifold will save your money spent on repairing it. You can do it with any welder meant for welding steel. MIG welding is suitable for this kind of job. However, the critical part of this process is cleaning and preparation work.

How to MIG weld stainless steel exhaust?

Like other MIG welding tasks, clean the base metal at first. Use a metal brush to clean the exhaust tubing and expose the base metal. Set the amperage rage to the medium to avoid burn. However, you can use a combination of carbon dioxide and argon to MIG weld stainless steel. This job can be done with regular MIG wire. But, stainless steel with nickel and chromium added to it make the weld join shiny and rust-resistant.

How to weld exhaust pipe with the stick?

Stick welding works for welding exhaust pipe through; still, you'll not get the perfect result. If you are stick welding, use a 6011 rod with the holder. Using the best welding rod for exhaust pipe reduces the chance of any leakage. Also, you can use 3/32” 6010 or 3/16” 7018 rods for a decent output.

How much to weld exhaust?

If someone with little experience welds your exhaust system, it would cost more than $200. There is a lot to do, like remove the exhaust, preparing, welding, putting new gaskets, and reinstall the exhaust.

How to seal exhaust leaks without welding?

Using epoxy, you can fix the smaller exhaust leaks and holes. The process is simple;

  • Detect the leak on the exhaust pipe
  • Clean the leaked area
  • Apply acetone on the leaking surface before applying epoxy
  • Apply epoxy and wait for 4-5 minutes to let it dry and fix the leak

How to weld aluminized exhaust tubing?

Aluminized steel exhaust tube resists corrosion, fire, heat, and oxidation. You can weld aluminized exhaust tubing with gas metal arc welding. Here you need to use mild steel filler metal and argon/oxygen shielding gas. Also, you can weld the exhaust tube with a MIG.

Can you flux weld exhaust?

Though you can flux weld exhaust, still we don't recommend it highly. You'll need many tools for this job, including a hacksaw, grinder, and exhaust tubing. Flux core welding tends to produce many slags, so you need to clean it thoroughly.

How much does exhaust welding cost?

It depends on the vehicle and the location of the leak. Repairing from an expert will cost you around $100 to $400. Also, it depends on the number of damages that happened in your exhaust.


Welding exhaust is not a big deal when you have the best welder for exhaust pipe. It saves a lot of money as well as you can weld anytime repairing needed. However, you can choose your best-fitted one from our reviewed welders.
