Laser welding is a melt welding process in which a laser beam is used as the energy source to impact on the weld joint.
Laser welding is a non-contact welding process that does not require pressure but requires the use of inert gas to prevent oxidation of the molten pool, which is occasionally used for filler metals.
Laser welding is capable of precise energy control, thus enabling the welding of precision micro devices, and it can be applied to many metals, especially for some difficult metals and dissimilar metals.
