Welding

After the fabrication process shapes the metal, it is then fused together through various techniques and methods. One common welding method is Arc welding, where a power source generates an electric arc between the electrode on the welding rod and the material, producing intense heat that melts the base material.

Common welding processes include:

• Shielded Metal Arc Welding (SMAW) - also known as manual metal arc (MMA), SMAW is one of the most common arc welding processes. Using a consumable flux-coated electrode that protects the weld area from oxidation and contamination, SMAW produces carbon dioxide gas during the welding process.
• Gas Metal Arc Welding (GMAW) - an automatic, or semi-automatic, process that uses a continuous wire feed. Since the electrode here in continuous, welding speeds are a lot greater with GMAW when compared to SMAW.
• Gas Tungsten Arc Welding (TIG) – TIG uses a semi-inert gas mixture in order to provide a welding process that uses a non-consumable tungsten electrode, an inert or semi-inert gas mixture and a separate filler material. This welding process often requires high levels of skill from the operator and is especially useful when welding thin materials. Though the process can be slow, it produces high quality welds.
• Flux-Cored Arc Welding (FCAW) – FCAW uses a wire consisting of a steel electrode surrounding a powder fill material. This wire if more expensive than standard solid wires and it can also generate fumes. However, it permits a high welding speed and great metal penetration.
