Compare with traditional argon arc welding machine, the laser welding machine is more economical, more convenient, and has better welding results. Laser welding has narrower welding seam and higher precision. It is more durable and more efficient with no need for secondary processing. It is also free from the rusting problem of argon arc welding on stainless steel material. One can do stitch welding, butt welding,and welding between different materials with the laser welding machine.
