Laser welding is an advanced welding technology that combines modern and traditional techniques but has different characteristics than traditional arc welding. It has obvious advantages such as anti-electromagnetic interference, fine weld seam, narrow heat affected zone, beautiful and smooth welding surface, high welding strength, safe non-contact, no back-melting problem, and high processing accuracy.

Here we quote the video from Vico.com to illustrate the advantages and development history of laser welding.
