Slag in welding refers to the hard layer created on the surface of a weld from non-metallic impurities that rise as the weld cools. Slag forms from flux used in the welding process combining with impurities and gases. While slag can protect the weld as it cools, it must be chipped away after to reveal … Read more
A Quick Answer for you: No, you cannot directly weld brass to steel due to their vastly different melting points. However, you can join brass and steel together using alternative techniques like brazing and soldering. Both methods involve melting a filler metal into the joint instead of melting the base metals. With proper preparation and … Read more
The best ways to prevent fogging in your welding helmet are to keep the helmet clean and dry, use anti-fog sprays or gels, ensure proper ventilation by keeping the vents open, adjust the helmet to fit snugly, and use a fan to direct air flow if possible. If fogging occurs, quick fixes include wiping the … Read more
Key Takeaways A Quick Answer for you The best way to get rid of welder’s eye is to see an eye doctor for a full assessment. They can provide prescription steroid/antibiotic eyedrops and recommend proper at-home care. For mild cases, you can try home remedies like cold compresses, cucumber slices and cold milk compresses to … Read more
Key Takeaways The choice between pushing or pulling the weld when MIG welding depends mainly on two factors – the need for strength versus aesthetics. Pulling the weld produces deeper penetration and results in a stronger weld joint. So for high stress applications, pulling is recommended. Pushing produces a wider, flatter, and better-looking weld bead. … Read more
You can solder without flux, but it’s not recommended. Flux plays an important role in cleaning and preparing the metal surfaces for soldering. Soldering without flux increases the risk of a cold solder joint, oxidization of the soldering iron tip, and inferior solder connections. The best options are to use flux-core solder wire or make … Read more
Welders often drink milk because there is a belief that it can help protect against metal fume fever, a flu-like illness that can occur from inhaling fumes when welding galvanized steel. The theory is that the calcium in milk binds to the heavy metals in the fumes, reducing their absorption. However, there is no scientific … Read more
The key tips for successfully welding an engine block are: 5 Tips to Successfully Weld an Engine Block Welding an engine block that has cracked or broken is a complex but achievable repair, if done properly. When faced with a damaged engine block, your first instinct may be to simply replace the entire thing. However, … Read more
Key Takeaways How to Weld Without Gas involves using a flux core MIG wire that allows you to weld without a shielding gas. For safety, wear fire retardant clothing, welding shield, eye protection, and respiratory protection. Prepare the metal by removing any contaminants. Set your welder to the proper amperage, wire speed, and wire feed … Read more
The right lens shade for TIG welding depends on the amperage used. For 50-150A, a shade 10 lens is recommended. For 150-500A, use a shade 12+ lens. Higher amperages require darker shades to protect eyes from intense UV radiation. Start with a shade 12 lens when in doubt. Adjust up or down based on puddle … Read more
