Continuing on AT&F’s tradition of close involvement with the U.S. Military and showcasing our respect for the men and women of our armed forces, AT&F has partnered with the Wounded Warriors Project to donate 40 trophies, laser cut and welded from stainless steel.

TIG Welding: Precision and Preparation
When a welding job requires precision, the obvious method to use is TIG welding. Gas tungsten arc welding (GTAW) is a welding method using tungsten as an electrode and argon or helium gas as a shielding agent. When GTAW was first introduced in 1941, it used exclusively helium as the shielding gas. This gave it its original name: Heli arc welding. It is now referred to as tungsten inert gas welding, or TIG for short. It is a slow and difficult method to master, but a trained welder can use TIG welding to produce very high quality welds. But what makes TIG welding so precision oriented? And why do TIG welders have to feed the wire by hand?
The History of Welding
For millennia, metals have been manipulated to man’s wants and needs. But from primitive hammers and anvils to high-tech robotic lasers, man’s methods of manipulation have changed and evolved drastically over time. The impact of advancements in welding has built skyscrapers, automobiles, and even nuclear reactors, but the genesis of welding looked nothing like the advanced technology we have at our disp
osal today. Paving the way for modern structures and safer machines, welding plays a crucial role in our daily lives.
