Laser welding machine application on stainless steel door handle

The door handle is the most common tool in our life. From ordinary padlocks to various types of advanced locks, the anti-theft door locks can be divided into pin tumbler locks, flat tumbler locks, magnetic locks, IC card locks, and fingerprint locks. The quality of the lock is related to not only the safety of everyone's property, but also the safety of life. Therefore, a good lock has great importance.

Nowadays, the most mainstream stainless steel door handle is the product with strong appearance. Therefore, the appearance of its outer surface must have no dents after welding and be seamless after polishing. The traditional welding technology has large weld seams and is easy to cause deformation. However, the Laser welding machine has small welding deformation, and the weld seam is smooth and beautiful, which perfectly solves the shortage of the traditional welding.

Shenzhen Sun Laser's YAG laser welding machine uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the material through heat conduction, and the material is melted to form a specific molten pool. It is mainly for the welding of thin-walled materials and precision parts, it can implement spot welding, butt welding, stitch  welding, sealing welding, etc. It has high depth-width ratio, small weld seam, little heat affected zone and deformation, fast welding speed, smooth and beautiful weld seam, no need further treatment after welding or only simple processing is needed, high weld quality, no air holes, precise control, small focus spot, high positioning accuracy, easy for automation.
