Is a Colored Weld a Good or Bad Thing?

While welders work hard to clean their metal work pieces, stack up their welds, and minimize spatter when laying beads, contaminated welds can sometimes happen. On occasions these contaminated welds will change colors. Sometimes a weld changes colors but isn’t necessarily contaminated. And sometimes welders

Why Welders Are Purging Pipes and Tubes Before Welding

Creating a strong, long-lasting weld requires a clean joint on your metal workpiece. When it comes to TIG welding uniquely shaped materials or pipe welding jobs, purging the metal of oxygen with an inert gas can keep the weld fully protected from oxidation that could

Tips for TIG Welding Aluminum at Your Home Shop

TIG welding aluminum often proves to be one of the most challenging welding processes for new and weekend hobby welders. Aluminum heats up faster than steel and most other metals in welding shops, and it becomes particularly brittle and prone to cracking if you aren’t

How to Choose A Shielding Gas for TIG Welding

You can’t cut corners in TIG welding–or at least you shouldn’t if you want to get repeat business or you want your welds to look good. While it seems like the standard plan for TIG welding is to always go with Argon as your shielding

How and When to Use Scratch Start TIG Welding

Tips for TIG Welding Aluminum on DC Power

Every welder knows that you’ll get a much cleaner weld that is more likely to pass inspection if you use AC power when TIG welding aluminum. There’s no debate there for the most part. However, you will find a far more spirited debate online about
