How Does Welding Work?
Welding is a fabrication process in which metals and thermoplastics are joined together to produce and object or structure. These materials are commonly joined by the melting of a filler material (such as steel) at their boundary points, fusing them together. This coalescence is achieved with three main techniques: gas welding, arc welding and laser welding.
Gas welding is the most common type of welding and also the oldest. This process works through the combustion of acetylene in an oxygen stream, with the gas funnelled to a point of focus where it is ignited to produce a high-temperature flame.
Arc welding differs to gas welding significantly. This technique involves melting the work materials through an electrical arc. This is generated by attaching a grounding wire to the welding material and then placing another electrode lead against it, itself attached to an AC or DC power supply. When the electrode lead is drawn away from the materials it generates an electrical arc (an ongoing plasma discharge caused by the electrical breakdown of gas), which through its expelled heat, welds the materials at the welding tip. Unlike gas welding, arc welding produces a narrow and concentrated weld point.
Laser welding – which is one of the newest and most expensive forms of welding – utilises a high-energy laser beam to fuse work materials. As the laser beam has a high-energy density, this technique can achieve a deep penetration and incredibly focused weld, with little surrounding distortion.
