Gas Tungsten Arc Welding
Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert shielding gas (argon or helium).

Plasma Arch Welding
Plasma arc welding (PAW) is an arc welding process very similar to TIG welding as the arc is formed between a pointed tungsten electrode and the workpiece.Plasma arc welding is an advanced form of tungsten inert gas (TIG) welding.

Submerged Metal arc
Submerged Arc Welding (SAW) is a joining process that involves the formation of an electric arc between a continuously fed electrode and the workpiece to be welded. A blanket of powdered flux surrounds and covers the arc and, when molten, provides electrical conduction between the metal to be joined and the electrode.

Plasma Transfered Arch
Plasma transferred arc (PTA) surface welding is a thermal process used to protect surfaces of metallic materials from wear and corrosion. Plasma transferred arc is a surface welding method, which enables a metallurgical bonding with the base material. It is versatile as it can be used on most alloys.
