Introduction
Laser welding is an advanced welding technique that uses a highly focused laser beam as a heat source to join materials. The process is commonly used to weld metals by directing a laser beam into the joint area, causing the materials to melt and fuse. Laser welding is known for its precision, speed, and ability to produce high-quality, durable welds.
Laser welder machine offers advantages such as high welding speed, excellent weld quality, minimal deformation, little to no need for post-processing, and the ability to weld refractory materials. The laser welding technology can achieve welding operations on complex shapes and inaccessible areas by precisely controlling welding parameters, solving problems that are difficult to overcome with traditional welding methods.
This article explores the diverse applications of laser welding across industries.
