The SPM Laser Welding is used for different applications like welding SS stator and end rings in submersible pumps and lower rollers for conveyors. Further this welding machine can be easily installed and have less maintenance needs. Laser welding is a process used to join together metals or thermoplastics using a laser beam to form a weld. Simply put, laser welding is a process in which lasers are used to melt the material on the surface of a workpiece. SPM Laser Welding is very efficient.
