01]Set the flow of pure argon shielding gas to 16 to 18 cubic feet per hour (CFH) for aluminum that's up to 0.500 inch thick. A percentage of helium can be added for thicker aluminum parts to increase ...

Spatter can originate from rapidly expanding gas bubbles in the weld puddle or in the metal drops that transfer from the end of the electrode. Expanding gases can cause drops to explode like an ...

Friction stir welding (FSW) is not necessarily a new welding process, but the implementation of it was slowed significantly ...

Last month, we presented the basics on setting up a TIG welder as the groundwork for the next few write-ups on actually making things with TIG welding. These TIG welding techniques aren't difficult—it ...

Having trouble getting welds to look like you want them to look? Maybe it’s because you can’t see what you’re doing. Controlling the “puddle” of molten metal is key to good welds. Welders often assume ...

VRTE X 360 is a virtual-reality arc-welding training system that lets students improve their welding skills in a simulated environment, lowering costs and reducing material waste VRTE X 360 is a ...

After botching many welding jobs, I have established baselines for any weld I now attempt: 1. Clamp the pieces, then add more clamps. Professional welders can strategically spot weld pieces they are ...
