Welding & Cutting ǀ Oxyacetylene (Oxy-Fuel) ǀ Process Tools & Types

Welding Malaysia

Welding is a technique that involves the joining together of two or more metallic pieces into one single piece of metal through heating, whilst the cutting process involves the separation of metal through heating. The metallic piece turns to a molten state after intense heating. There are several types of welding and cutting processes, such as gas welding, arc welding, forge welding, resistance welding, spot welding, oxyacetylene welding, electron-beam welding, friction welding, cold welding, laser welding, etc. In terms of the weldability of metals, carbon and low alloy steel are the materials used most widely in welding. Besides, aluminium, copper, nickel, and refractory metals such as zirconium, niobium, and tungsten can be welded by using the right welding process.

Arc Welding

Arc welding is a process of welding that uses an electric arc to produce strong heat to melt metal. The arc is formed between the metal and an electrode which carries current, melts, and transfers the filler metal to the joint. The temperature the arc produces melts the metal and the electrode, which turns the metal into a molten state. There are a few types of arc welding. The common types are such as shielded metal arc welding, gas metal arc welding, gas tungsten arc welding, and plasma arc welding.
