Welding Characteristics

It is a fusion welding method, which uses a laser beam as energy and impacts the weld joint.
The laser beam can be guided by a flat optical element (such as a mirror), and then projected onto the weld by a reflective focusing element or lens.
Laser welding is a non-contact welding method, and the operation process does not require pressurization, but an inert gas is required to prevent oxidation of the molten pool, and filler metal is occasionally used.
Laser welding can be combined with MIG welding to form laser MIG composite welding, achieving deep penetration welding, while the heat input is greatly reduced compared to MIG welding.
