Arc Welding

Arc Welding is the process of joining metal to metal using an Electric Arc.

The Electric Arc creates intense localised heat between the workpiece and the metal electrode. When the arc is initiated it almost instantly melts both the workpiece and electrode.

The metal from the electrode mixes with the molten metal of the workpiece, as the electrode moves the bead of molten melt cools creating a strong homogenous weld.

The arc itself forms a protective shield over the weld preventing oxidisation and the production of nitrides. Chemical cleansing agents are often present in the electrode to remove impurities from the weld, resulting in a stronger, purer weld.

Arc Welding is one of the most common welding processes in the world. It is highly skilled but produces high quality welds and is widely used in automotive, construction, marine and aerospace industries to name a few.

The process of Arc Welding can be broken down into these sub categories:

• Metal Inert Gas Welding

• Tungsten Inert Gas Welding

• Manual Metal Arc Welding

• Submerged Arc Welding

• Plasma Arc Welding
