While one of the most widely used and accessible methods of welding, gas metal arc welding (GMAW) is actually a balancing act of many important variables that greatly affect the quality of the weld. Commonly known as MIG welding (short for “metal inert gas”), this method utilizes a consumable metal as an electrode like shielded metal arc welding in the form of a wire. The wire is fed semi-automatically or automatically through a gun that supplies the shielding gas necessary for protecting the weld pool from exposure to the atmosphere.

Chemical heat exchangers, dealing with volatile chemicals at high temperatures, are prone to corrosion. Fortunately, tantalum is one of the most corrosion resistant metals on earth. AT&F Advanced Metals has experience with many specialty metals, including tantalum, and have manufactured many tantalum heat exchangers, lined pressure vessels, and other specialty application components that make use of the metal’s properties.

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?

As he was interviewing for his current position as business unit leader of AT&F Wisconsin about two years ago, Joe Girard noticed a small saying at the bottom of a job description he was perusing: “The company is in its fourth generation of family leadership. While the values of the organization are similar to those found in family-run firms, the company is sophisticated and professional without being pretentious.”
