Welding And Fabrication

At AAP, we use three main types of welding processes in our metal fabrication projects: MIG Welding, Spot Welding, and TIG welding. The type of welding process we choose for each project depends on several factors including the type of material, the thickness of the material and the desired results.

Metal inert gas welding (MIG)

The metal inert gas welding process uses a consumable electrode which can be in the form of copper-coated coiled wire. The same gas as TIG welding, argon is used to shield the weld from the atmosphere. As with TIG welding, a direct current is used but with the electrode (wire) being electrically positive and the sheet metal workpiece electrically negative to generate more heat therefore melting the electrode.

Spot Welding

Spot welding is one of the oldest methods of welding and fabrication. In this process, no filler material is used to weld the two pieces of metal together. Instead, pressure and heat are supplied to the weld area through two shaped copper alloy electrodes. The welding current is concentrated in a small spot; melting the materials and allowing the two parts to fuse.

This process is usually used for sheets of stainless steel or aluminium which are in the 0.5-3mm thickness range. Spot welding delivers a lot of energy to the weld area in a short amount of time, making this a very attractive process as it does not cause unnecessary heating to the rest of the metal sheet.

TIG welding

TIG welding, or Tungsten Inert Gas welding, is one of the most difficult welding processes to master.

In this process, the arc uses a non-consumable tungsten electrode, in contrast to the consumable electrode used in MIG welding. As the electrode in this scenario does not melt, a thin wire of filler metal is fed into the welding area, which then melts and joins the two parts together.

TIG welding is commonly used on stainless steel and aluminium, as well as magnesium and copper alloys like brass.

Although this process is difficult to master, it gives the welder considerably more control over the weld, creating stronger, high-quality welds. A disadvantage of this type of welding is that it is slower than other processes, however, this is outweighed by the benefits of a neat and tidy weld.
