Tungsten Inert Gas (TIG) welding—more formally known as Gas Tungsten Arc Welding (GTAW)—is well-suited for welding aluminum. Although the process is significantly slower than GMAW (MIG), TIG welding offers unmatched control of weld penetration and profile. This level of control is enhanced by the features available on modern TIG welders.
When it is tough to bring the workpiece to a source of power, it is often necessary to bring the power source to the workpiece. By combining the capability of a welding power source with the functionality of a portable generator, the engine-driven welder generator often becomes one of the most versatile pieces of equipment on the jobsite.
Engine-driven welder generator rentals power all sorts of job sites. The “mobile welding rig”—a work truck outfitted with an “engine drive” welder— is a common sight alongside the spans of onshore pipelines, heavy equipment in need of repair, or structural and bridge construction sites. Of course, equipment trailers are a popular accessory for those who need to free up bed space.
A vast array of equipment power plants and feature sets ensure that both the home hobbyist and professional welding outfit can access the power and processes they need in the field. A home hobbyist unit may start out having a gasoline engine providing a 4.5 kW single-phase maximum output while some of the largest dual-operator units are diesel-powered and offer maximum three-phase outputs of approximately 25 kW.
Induction heating is a modern approach to supporting the welding process with preheat and post-weld heat treatment (PWHT) as well as other industrial tasks such as coating removal and placing or removing shrink-fit components. Although the conventional use of induction heating is limited to magnetic base materials, applications capable of using the process can reap significant operational savings and benefits compared to “conventional” heating processes such as flame/torch or even resistive heating. Could you be a good candidate for implementing induction heating into your welding or industrial maintenance processes? Shown here are just a few target use cases.
