What is the working principle of laser welding?

Laser welding is a process that uses a laser beam with a high energy density as a heat source to melt and connect the surfaces of two or more metals.

The laser beam concentrates the energy at a single point through the focusing lens, generating high temperature that melts the metal. Then, through cooling and solidification, a weld seam is formed.

Laser autogenous welding

It uses a laser beam to directly melt the base metal without the need to add solder, and is often used for the welding of thin plate materials without gaps.

Laser wire filling welding

A welding wire is added into the laser beam to realize wire filling during the welding process, which improves the strength and toughness of the weld seam and can adapt to relatively small assembly gaps.

Laser-arc hybrid welding

Combine laser welding with arc welding, making use of the advantages of both to achieve efficient and high-quality welding.

Handheld laser welding

It features simple operation and high flexibility, and is suitable for the manual assembly and welding of thin - plate components.

Platform laser welding

It has good stability and high welding precision, and is suitable for welding small workpieces.

Robot laser welding

It has a high degree of automation, a fast welding speed and stable welding quality, and is suitable for automated welding in mass production.
