Laser Junction’s welding unit consists of thirty qualified, skilled and experienced welders capable of MIG or TIG welding. The Company also undertakes precision and seamless robotic stainless steel welding. We are comfortable in large-scale sheet, spot or tube welding environments.
In this welding process, an electric arc is formed between a consumable wire electrode and the metal, which heats the metal, causing them to melt, and join together. MIG welding is ideal for welding thicker gauge material.
TIG welding is a process that uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an inert shielding gas (argon or helium), and a filler metal is applied. TIG welding is a slower and more specialised process than MIG welding and is best used for the welding of complex parts that require high quality finishes. It is also mainly used for the welding of stainless steel and aluminium components.
The robot welder uses the MIG welding process and this generates a consistent, high quality weld and is ideal for the fabrication of high volume parts. The robotic system consist of three work stations, each of which can accommodate several parts in a jig and while one workstation is being welded, the other work stations can be loaded / offloaded.
SPOT welding can be used for material from 0.5 to 3mm in thickness. The contacting metal surfaces are joined together by the heat obtained from the resistance to electric current – the process is applied using two shaped copper alloy electrodes that concentrate a welding current into a small “spot” and to simultaneously clamp the sheets together. Forcing a large current through the spot will melt the metal and form the weld.
