Manufacturing process application of aluminium alloy ladder laser welding machine

Ladders are a must-have tool in our daily work life. About a quarter of high falling accidents are caused by improper use of the ladder and unstable quality. These accidents often cause irreparable damage and injury.

The aluminum alloy ladder is made of high-strength aluminum alloy material, which is characterized by its light weight and high strength. It greatly facilitates the construction workers' work. At present, there are many manufacturers of aluminum alloy ladders, and the quality of the ladder is related to personal safety.

The traditional welding method is argon arc welding, because the heat affected zone of argon arc welding is large, the workpiece has defects like deformation, hardness reduction, sand hole, local annealing, cracking, pinhole, abrasion, scratch, undercut, or insufficient bonding force and internal stress damage etc. And argon arc welding also causes certain damage to human body.

Laser welding technology used for welding aluminum alloy ladders, it has smooth and beautiful weld seam, small width, small heat affected zone and little deformation. Compared with traditional argon arc welding, the molten pool is stirred constantly in the process of laser welding seam formation, the gas escapes, and the non-porous penetration weld is formed. The high cooling speed after welding tends to make the weld microstructure fine, and the weld strength, toughness and overall performance are high.

The aluminum alloy ladder Laser welding machine adopts non-contact processing welding, it has no physical contact with the workpiece, so there is no force on the workpiece, and the welding product will not be deformed. Due to high power density, the melting process is extremely fast, the workpiece input heat is very low, and the welding speed is fast.
The YAG laser welding machine developed by Shenzhen Sunlaser uses high-energy pulsed laser to weld the workpiece. Because of its small focusing spot, the welding can be positioned with high precision and can be applied to the welding of various metals and alloy materials such as alloy and steel.
