What is the difference between laser welding technology and robot welding? With the continuous development of welding technology, various welding processes have begun to develop. Among them, laser welding technology is widely used in various fields. Laser welding has the advantages of high energy density, small deformation, and fast welding speed.

The Difference Between Laser Welding And Robot Welding

This article will take you to understand laser welding The difference between technology and robotic welding.

  • 1. The welding accuracy is different. The welding position of laser welding needs to be accurately welded, and the welding work needs to be carried out within the focus range of the laser beam, which can reach 0.1mm, the welding accuracy is very high, and some parts with small spacing can be welded; most of the robot welding is The way of teaching and reproducing requires setting the welding program, including welding speed, welding spot position, etc., and different programming is required for different welding seams.
  • 2. The specifications of welding materials are different. Laser welding is suitable for thin materials and thin wire welding. The thickness that can be welded is limited. It cannot weld workpieces over 19mm. Laser welding is not suitable for production lines. Robot welding does not require particularly high overall dimensions. The welding robot has deviation sensing and The arc tracking function in the welding process, so the workpiece with different thickness will be compensated during the welding process.
  • 3. Different welding methods. During laser welding, the welding torch does not need to use electrodes, there is no worry about electrode contamination and replacement of the welding torch, and non-contact welding can be used, and the wear and deformation of related parts can be reduced; the robot welding achieves contact welding, and the welding torch is required as a wearable part. Regular replacement, and the welding gun needs to be cleaned during work, which affects the work process.
  • 4. The welding environment is different. Both laser welding and robot welding can work in harsh environments. Laser welding can work in a vacuum environment; robot welding can be customized according to different use environments.
  • 5. The welding quality is different. Laser welding has a fast local heating speed, small impact on peripheral components, and small welding deformation. Robot welding is fixed with tooling fixtures, and certain measures need to be taken to reduce the deformation of the workpiece.
