The first thing to know is what polarity is used to weld on aluminum with GTAW. A common misconception is that you need ...

After years of self taught point-n-shoot MIG welding around the home shop, I was finally offered the opportunity to get a bit of an actual welding education. A few weeks ago, Miller Electric ...

Welding gases and thermal process gases are especially formulated for welding, cutting or other high-temperature processing applications; either because they produce a large amount of heat or provide ...

Welding fumes are very small particles that are formed when the vaporized metal rapidly condenses in air. They are typically too small to be seen by the naked eye but collectively form a visible plume ...

Humans have been welding at least since the advent of the first horseshoes and wagon wheels. Back then, the village blacksmith didn't have screw threads or Cherry rivets, electricity or gas. For those ...

Welding alloys, also known as filler alloys, are consumables used during a welding process to fill in the gap between two edges being joined. The filler alloy melts into the weld pool along with a ...

Among the different varieties of welding techniques — which include gas (such as the oxyacetylene method), laser, ultrasonic, and others — the most common type today is electric arc welding. This ...

Although some engineers have had success in spot welding steel and aluminum together, it has largely been considered impossible to achieve reliable, continuous welds directly between the two ...
