WeldingWelded Sheet Metal Specialty Company employs all of the common welding techniques to create permanent, durable welds for a variety of metalwork projects. We take great care to evaluate your project and select the most appropriate welding technique accordingly.


Types of Welding at Welded Sheet Metal Specialty Company

MIG Welding

Metal Inert Gas (MIG) welding—also known as Gas Metal Arc Welding (GMAW)—involves running shielded gas along a continuously fed wire electrode to melt and join two pieces of metal. While MIG welding is widely considered the most common and versatile technique, it is best suited for materials of lighter gauges. This method requires a reliable DC power source.

At Welded Sheet Metal Specialty Co., we use a Lincoln Electric 300 amp welder for optimal performance.

MIG welding offers a number of benefits over other techniques:

  • Fast, efficient production of high-quality welds
  • Produces very little weld splatter, minimizing loss of alloying elements
  • No possibility of slag entrapment, which may harm the quality of a finished weld


TIG Welding

Tungsten Inert Gas (TIG) welding—also referred to as Gas Tungsten Arc Welding (GTAW)—is a better alternative for materials of heavier gauges. The main difference between MIG and TIG welding is that TIG welding uses a non-consumable tungsten electrode to form the weld pool. We perform high-quality TIG welding with quality Miller 250 amperage equipment.

TIG welding carries its own set of unique benefits and use cases:

  • Creates strong, durable finishes on heavy-gauge materials
  • Minimizes flame, spark, and slag production
  • Requires little-to-no finishing work to achieve an aesthetically-pleasing joint
  • Generates very little distortion in the final product due to a reduced heat zone
  • Works with a wide range of materials and automation techniques


Steel Spot Welding

In contrast to TIG or MIG welding, Resistance Spot Welding (RSW) uses two copper alloy electrodes. Welded Sheet Metal Specialty Company can spot weld steel and stainless steel up to 0.125 inch thick.

Advantages of RSW include:

  • Generates a uniform weld pattern with little warping or distortion
  • Requires no edge preparation and can be performed in quick succession
  • Comparatively affordable


Advantages of Welding

Although each welding technique has its own set of pros and cons, they all share similar advantages. The primary reason to consider welding is that it creates extremely strong joints with the two pieces of metal eventually functioning as one. Compared to rivets or fasteners, a welded joint can withstand force more evenly and efficiently, increasing structural integrity.
