Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser processing technology. Laser welding can be realized by continuous or pulsed laser beam. The principle of laser welding can be divided into heat conduction welding and laser deep penetration welding. So how does a laser welding machine weld a perfect high-quality weld? This post provides some references for you on how to improve the welding effect.

 

Choose the right laser welder and safety aids

Choose the right laser welding machine according to the actual needs of the welding process to best match the process to the application. Factors that should be considered are: type of welding material, material thickness, welding location, type of welding power source and amount of current available, and time requirements. The first thing to consider before getting started with a laser welding machine is making sure you have the correct safety equipment. This includes gloves and laser goggles.

 

Keep the correct distance and make sure the material is clean

When laser welding, it is important to maintain the correct distance from the laser welding gun to the workpiece. Too close, the tip will wear too much; too far, the energy value will be reduced, which will lead to poor soldering. Any oil, rust, paint or scale can cause contamination and cause poor welds. Before starting the welding process, remove contamination from the surface of the material to ensure all material is clean.

 

The laser beam of the laser welding machine can be focused on a small area, can weld small and closely spaced parts, can weld a wide range of materials, and can also bond various dissimilar materials to each other. By welding the right way, you can get a perfect weld.
