Spot welding


Dawson’s highly skilled craftspeople use one-of-four of the latest, and trusted, welding techniques in our manufacturing process, to fuse your project’s custom pieces.

Dawson has numerous spot welding machines suitable for welding various materials.  Our newest spot welding machine is the Amada ID40IV HP NT.  The ID40IV HP NT features the latest inverter spot welding technology that is capable of consistently producing high-quality sparkless welding. Vertical press type welding combines the power of inverter technology with the accuracy of a microcomputer controller. The integrated AMNC PC touchscreen control provides storage and editing capabilities of welding programs and conditions.

AWS Certification

Many of our welders are AWS (American Welding Society) certified.  Being AWS certified indicates that the welder has completed a welder performance qualification test.  Dawson uses an AWS CWI (Certified Welding Inspector) to produce documentation, welding procedures and to qualify welders.


  • Metal Inert Gas (MIG) Welding

    A quick, semi-automated arc welding technique, joins two base materials together. The mechanism involves a continuous solid wire electrode, being fed through a welding gun and into the weld pool. Simultaneously, a shielding gas is also sent through the welding gun, protecting the weld pool from contamination.

  • Tungsten Inert Gas (TIG) Welding

    Requiring a higher skill level, this manual arc welding process uses the heat of an electric arc between a tungsten electrode and the base metal; a unique mechanism that sets this method apart from the rest. A separate welding filler rod is fed the molten base metal, if needed, and a shielding gas flows around the arc to keep air away, and other impurities.

  • Robot MIG Welding

    A fully automated technology, this welding technique involves an ARC Msate 120iB robot within Dawson’s Robotic Weld Cell. This technique requires our skilled welders to load, and unload fixtures and inspect product through to completion. The Weld Cell is set up with two weld tables containing a series of holes that allow for modular fixturing.

  • Spot Welding

    Efficient, safe, clean, and environmentally conscious, this welding technique is a reliable mechanism for the formation of an electro-mechanical joint. Dawson’s facilities house many spot welding machines suitable for welding various materials, such as steel, stainless steel, aluminum and brass.

Common spot welded materials:

  • Steel (CRS, HRPO & Galvannealed)

  • Stainless Steel

  • Aluminum

  • Brass

Spot welding process advantages:

  • Very short process time

  • No consumables, such as brazing materials, solder, or welding rods

  • Operator safety because of low voltage

  • Clean and environmentally friendly

  • A reliable electro-mechanical joint is formed
