The optical fiber continuous automatic laser welding machine not only realizes the welding of various metals, but also with the more distinctive products that various industries want to create, and the widespread application of equipment, the entire market has become active, not only for enterprise manufacturing , more for our daily necessities DIY.

   Welding aluminum, copper, titanium alloys and other materials is essential for industrial processing, and the optical fiber continuous automatic laser welding machine can handle various metal welding, including low carbon steel and aluminum, copper, titanium alloys, etc., which is a must for industrial metal product marking. However, there are various technical difficulties in the welding of aluminum alloys by laser welding machines. 

Due to the rise time of the fiber laser pulse and the characteristics of high beam quality, the heat input is small and the heat source is concentrated. The energy density of laser welding aluminum, copper and titanium alloys is more concentrated, the laser wavelength is shorter, and the reflection is high. Improved, especially for metal welding.

In a given optical system, the size of the laser spot with higher output beam quality is smaller, so the processing efficiency can be improved. For most materials, through laser wire filling, laser-MIG hybrid welding, dual-spot laser welding and other processes, the forming effect of aluminum alloy welding can be significantly improved, the metal with rough surface has a high degree of sandblasting, light reflectivity and clean surface , thus marking less laser energy input and improved welding quality.

Welding process introduction

At present, the optical fiber continuous automatic laser welding machine mainly adopts conventional methods such as TIG welding and MIG welding to weld aluminum alloys. No matter what kind of welding method is used, the preparation work before welding of aluminum alloy is indispensable, which has a great influence on the welding quality of aluminum alloy.

●Before welding, wipe the surface of aluminum alloy parts with anhydrous alcohol or acetone to remove impurities such as water or oil adsorbed on the surface;

●To prevent the workpiece from being oxidized in the air, the workpiece needs to be mechanically polished or chemically treated and dried to complete the welding as soon as possible;

●In order to speed up the fluidity of the molten pool during welding of aluminum alloys, a copper pad can be added to the back of the aluminum alloy workpiece to improve the weld formation;

●When welding, use Ar gas protection to isolate the air and reduce the generation of pores.
