What is Pipeline Welding?

When it comes to pipeline welding, many people confuse it with a welding piping system. Pipeline welding is absolutely different from piping welding. However, piping welding is a process of welding piping systems in industries.  Pipeline welding, on the other hand, is done on the distribution pipelines used for transporting oils, gas, and water. They deal with pipes that may span hundreds of kilometers. Whether it’s Alaskan snow or Arizona heat, pipeliners need to go where they are called.  Pipeline welders do the installation, repair, and maintenance of pipelines. Installation of pipes meaning assembling different sections of pipes. That’s where you need the best pipeline welding machine.  When pipeline welding is done with a welding machine, you don’t need a threading tool at all. Moreover, pipeline pipes contain harmful contents. Pipeliners have to comply with strict specifications. Using the right tool for welding and safety standards is paramount. 

Why Do Pipeline Welding Require a Special Welder?

For starters, it is crucial to know why they need a particular welding machine for pipeline welding. Here is why. Pipeline welding asks for quality and performance. Primarily, pipelines are welded on-site where the pipelines are aligned and beveled. So then comes a lot of challenges pipeliners face on the field.  Pipeliners cannot think of a better alternative than the best welder for pipeline welding. The reason behind this is not only the thickness of the pipes, power, or amps. There are more reasons why a pipeline welder needs dedicated welding machines. 

  • Maximizing Welding Productivity and Avoiding Downtime

Nowadays, pipeline welders must meet challenging quality standards along with deadlines. Then, they are supposed to cut downtime so they can maximize welding production.  A quality pipeline welding machine helps to maximize repair rates. Also, it allows adjusting to new types of pipes on the field. The pipeliners can stay competitive while maintaining their quality of work with the best pipeline welding machine.

  • Ensuring Quality and Speed

Traditional SMAW (shielded metal arc welding) methods have been used for low-carbon and low-alloy steel pipes for decades. It becomes the pressure for pipeliners to produce high-quality welds on sites.  The metal technologies and downhill welding techniques have remained unchanged in those traditional welders. So, it is close to impossible to speed up welding to meet project timelines. While looking to maximize the quality and speed, a pipeline welder needs the best welding machine.    Oil, gas, and other industries cannot avoid pipeliners that put their demand at the top.

What Pipeline do Welders Require for Pipeline Welding?

First of all, pipeline welders require thorough training and skill in pipeline welding. Pipeliners, unlike welding in a workshop or garage, work in tougher environments and angles. So, they need more than average skills in welding.

A pipeliner needs 2000 hours or more of full-time work experience to be a proficient pipeline welder. They must adopt the following welding techniques;

  • Shielded Metal Arc Welding (SMAW)
  • Gas Tungsten Arc Welding (GTAW)
  • Submerged Arc Welding (SAW)
  • Flux-cored Arc Welding (FCAW)
  • SMAW with low hydrogen vertical down electrodes

Pipeliners also need to learn to use tools, pipe system design, safety, and mechanical drawing. A certification course is required to acquire all these skills and knowledge. Most of all, a pipeline welder must have problem-solving skills.

So they can diagnose and solve the challenging issues found in different working conditions. Physical stamina is another crucial requirement for a pipeliner welder. They must have enough strength to withstand harsh working conditions.

Things to Look for in the Best Welder Machine for Pipeline

Proper skills, experience, and knowledge may not make you the best pipeliner if you lack suitable equipment. Keep in mind that you’ll be welding too thick pipelines, mainly in harsh environments.

So, one of the basic necessities is a powerful welding machine. Opt for a machine that offers reliable power for a range of operations. How do you find if the machine meets all the requirements for the best results?

Well, there are a couple of factors you need to check in a welder. Let’s find out.

Power Output

Pipeline welding is unpredictable. Indeed, the varying thickness of the pipelines and working condition demands for more power in a welding machine. The power output of a welding machine denotes the power of the machine.

A welder with amps output of 120-140 amps will be enough for domestic purposes. However, a higher amps output is needed for more demanding projects. For outdoor pipeline projects, you’ll need a welder with 200- 300 amps power.

Moreover, it is good to buy an engine-driven welding machine that also works as a generator. So you can maintain operation for a day. Most pipeline welders come with an in-built generator.

Duty Cycle

Then comes another crucial factor which is the duty cycle. The duty cycle is the fraction of the period within which a welder can produce current without overheating. Let’s clear the definition with an example.

Say, a machine is rated 150A with a 70% duty cycle. It means you have to rest the machine for 3-minutes following 7-minutes of operation at 150A. Operating at lower amperage gives you a higher duty cycle.

Look for a welder that offers a higher duty cycle for specific power output. Most professional-quality welding machines provide a 100% duty cycle even for output 250A.

Gas Or Diesel Driven?

The engine of the welder may be gasoline-driven or diesel-driven. Check into the welding machine to learn what fuels the engine. Whichever type you prefer, make sure it is cost-saving. A gasoline-driven welder is the best pick if you are on a budget.

Power Source

If the machine is electric-powered, it is essential to the power source. The power source depends on the job site like most industries have a 230V/240V power outlet.

As a nomad pipeliner, you never know what power source you may need. It is wise to choose a machine that operates on both 110V and 230V power sources. Thus, you can plug it with any power outlet.


Safety comes first. While investing in a powerful machine, it is essential to check the safety features. Some pipeline welding machines include built-in surge protection. Those have a protection level of 20%-25%, which is the best level of security.


The materials and thickness of pipelines ask for using different welding techniques. The techniques used in pipeline welding are mostly MIG, TIG, Stick, flux-cored, and GTAW.  Only MIG or TIG or stick welder will not be sufficient.

You need a machine that works well with thicker pipelines using any techniques. Welding machines that are restricted by the scale or thickness of the pipelines will not do. Your pick should be the one that goes well with all types of welding techniques.


Pipeline welders are nomads; they need to go wherever they are called. They travel around along with their welding equipment. Keeping it in mind, you need a machine that is easy to carry around.


What is the best welding machine for pipeline?

The best welding machine is the one that fits varying thickness and materials of pipelines. Also, a machine that can perform all the welding techniques is the best. The machine engines that can produce 9500-11000W with less fuel consumption are the promising ones. They can generate up to 300A power output for your welding needs. Well, the Lincoln Electric Ranger 305 is one such example.

What kind of welder do pipeliner's use?

Mostly, the pipeliner's use MIG welders for pipeline welding. MIG welder utilizes an arc welding process where a wire feed is used through an electrode. The electrode remains inside a handheld welding gun.

Are pipeline welders in demand?

Absolutely, they are. Pipeline welding is one of the most in-demand jobs in the welding sector. This is the most challenging job, which requires extraordinary skills and knowledge. Being an expert in this field brings you lots of opportunities. Natural gas and oil industries are the largest employers of pipeliners. They offer exciting salaries and many other traveling opportunities.

How much do Pipeline welders make an hour?

As mentioned, pipeline welding is the highest paying gig in this sector. A pipeliner can make $57000 or more per year. They can make between $36-$52 per hour on arm pay and $15-$25 per hour for the truck pay. Also, a pipeliner can make between $100 and $200 for the per diem. The amount a welder receives is based on their skill and experience. As welders gain knowledge and experience, they get a higher amount per hour.

What is the salary for a pipeline welder?

A pipeliner gets a handsome salary for what they do. On average, a pipeliner is paid around $5000 - $6000 per month. They make around $70000 per year. The top earners, on the other hand, can get up to $100,000 per year.

Final Words

Pipeline welding is a cakewalk like other welding jobs. It requires expertise, experience, and most importantly, the best welder machine for pipeline. So, investing in the best machine is no brainer to remain competitive in this field.

Although we’ve sorted the list, so you don’t get confused. We want to repeat once again that the machine should have a standard output amp of 300A. Then, the engine should generate the highest power.

You can pick one from the machines mentioned above as they all meet these criteria. Good luck with your purchase.
