Welding is a process whereby two pieces of material are joined together through the application of heat. Welding is predominantly used on metals, but some plastics - as well as wood - can also be used. It works by melting the workpieces and fusing them together, with filler material usually being melted alongside the workpieces to ensure a strong bond between the two.
There are various types of welding processes that are all suited to different types of materials. Arc welding relies on the creation of an electrical arc to melt the workpieces and fuse them together, whilst gas and lasers can also be used to heat the material. Metals that are suited to the welding process include aluminium, steel, stainless steel, titanium, cast iron, copper, magnesium alloy and brass.
