The metal channel letters are made of stainless steel, brass, tinplate, galvanized sheet, cold rolled sheet and other metal plates. The traditional welding methods of metal channel letters include electric welding, gas welding, argon arc welding, etc. because the traditional welding machine is easy to produce burn marks on the reverse side when welding thinner metal, and it is obviously deformed after burn, the use of thick metal plates is costly and heavy, It increases the difficulty of outdoor installation. The use of laser welding is different. The laser welding machine welding channel letters has little thermal impact on the material, will not deform the material, and the welding effect is also very beautiful.
As a new type of laser equipment in the advertising industry, laser welding machine has gradually replaced the traditional welding process by relying on its advantages of simple operation, good welding effect and low consumables.
Laser welding machine has high aspect ratio, small weld seam width, small heat affected zone, small deformation and fast welding speed; The weld is flat and beautiful, and there is no need for treatment or simple treatment process after welding; It has the advantages of high weld quality, no pores, reduction and optimization of base metal impurities, refinement of microstructure after welding, high weld strength and toughness.
It is precisely because the laser welding machine has good welding effect and simple operation. Compared with the traditional welding, it eliminates a manual grinding procedure. In addition, its products are more high-end and many other factors have established its position in the advertising identification industry.
