Advantages of fully automatic laser welding process?

       Laser welding 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 to achieve the purpose of welding. It is a new type of welding method, mainly for the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, stitch welding, sealing welding, etc., with high aspect ratio, small weld width, and small heat affected zone. Small deformation, fast welding speed, smooth and beautiful welding seam, no need to handle or simple processing after welding, high welding seam quality, no air holes, precise control, small focus spot, high positioning accuracy, easy to realize automation.

       Laser welding has significant advantages that traditional welding methods cannot match: small heating range, narrow welding seam and heat-affected zone, excellent joint performance; small residual stress and welding distortion, high-precision welding can be achieved; high melting point, high thermal conductivity, Heat sensitive materials and non-metals are welded; the welding speed is fast, the productivity is high; and it is highly flexible.

       The fluorine side head of HZSS's new shell and tube heat exchanger uses laser welding instead of the traditional head bolt gasket for forced sealing; the pressure is high, and there is no risk of leakage on the fluorine side. And the penetration depth is large; the penetration rate is high; the heat affected zone is small, and the cooling is extremely fast.
