MIG, TIG, RESISTANCE, AND ROBOTIC WELDING
Metal Inert Gas (MIG) welding is a gas metal arc welding (GMAW) process that uses a continuous solid wire electrode which is heated and fed into the weld pool from a welding gun (or torch). The two base materials are then melted together, causing them to join. The welding gun also feeds an inert shielding gas alongside the wire electrode, which helps protect the process from airborne contaminants.
MIG welding provides a uniform, slag-free weld bead and can be used in all positions. It requires less operator skill than TIG welding and needs very little cleanup.
MIG welding is a high productivity welding process as the wire (electrode/filler metal) is continuously fed, allowing long welds to be made without starts and stops. It can be done manually or automated via robotics.
MIG welding can be used on aluminum, stainless steel, and carbon steel, from 24-gauge sheet metal up to heavy-duty structural plates and shapes. It is common for Staub to use MIG welding for fabricating frames, mounts, arms, brackets, and carts.
Tungsten inert gas (TIG) welding is a gas tungsten arc welding (GTAW) process that uses a non-consumable tungsten electrode that delivers the current to the welding arc. In TIG welding, an arc is formed between a non-consumable tungsten electrode and the metal being welded. Gas is fed through the torch to shield the electrode and the molten weld pool. If filler wire is used, it is added to the weld pool separately.
TIG welding produces a sound, slag-free weld bead. It allows for a large amount of control, making it a good weld process for highly-detailed projects. Because of its relatively small arc, it is well suited for welding thin sheet metal, producing low distortion and no spatter.
TIG welding can be used on aluminum, stainless steel, and carbon steel from 24-gauge sheet metal up to 1/8” thick sheet and structurals. It is common for Staub to use TIG welding on light-gauge sheet metal brackets, custom electrical enclosures and intricate welded assemblies.
Resistance welding is the process of joining metals by applying pressure and passing a current through the materials to be joined. This procedure is very cost-effective because it is fast and requires no additional (filler) materials to create the bond.
The two types of resistance welding Staub Manufacturing provides are:
Spot Welding: Spot Welding utilizes the faces of opposing electrodes (typically made of a copper alloy) to apply force to overlapping sheet metal surfaces and focus the current at the desired weld location. A weld nugget will form after sufficient resistance (heat) is generated, and the materials combine. Spot welding is a fast, reliable way to construct sheet metal products such as custom electrical enclosures, frames, mounts and various multi-part assemblies.
Projection Welding: Like Spot Welding, Projection Welding also uses heat generated by resistance. Instead of focusing the current at one location, Projection Welding welds at predetermined points by using projections, embossments, or intersections, along with heat generation at the point of contact. When sufficient heat is generated, the projections collapse, forming a weld nugget. This process is used by Staub to efficiently attach weld fasteners such as nuts, bolts, pins, and studs to a variety of sheet metal products.
