The comprehensive laser welding robot process encompasses the following key steps:

  1. Preparation

Prior to welding, meticulous preparation takes place. This involves tasks such as deburring, grinding, and cleaning of the workpieces. Additionally, welding parameters and the welding program are meticulously set.

  • Welding Position Establishment

The robot employs a sophisticated coordinate system to accurately determine the precise location of the workpieces to be welded.

  • Welding Head Alignment

The welding head is meticulously positioned by the robot in accordance with the preset welding program.

  • Welding Operation

The robot concentrates the laser beam onto the welding area, resulting in the surface of the workpiece being heated to the point of melting. This facilitates the bonding of the metals at the connection point. Throughout the welding process, the robot employs laser monitoring and tracking to ensure impeccable precision.

  • Cooling Phase

Upon cessation of laser irradiation, the robot initiates a cooling process. This swift cooling promotes the rapid stabilization of the welded area, ensuring a durable connection.

  • Finishing Touches

With welding concluded, the robot retreats from the welding head. Subsequent tasks, including cleaning the welding head and recording essential welding data, are carried out.


The laser welding robot’s prowess lies in its incorporation of a laser welding head. This equipment’s central principle revolves around utilizing laser beams to elevate the temperature of the welding area. The swift elevation in temperature leads the metal to reach its melting point promptly, resulting in successful welding. This amalgamation of high precision and efficiency marks the hallmark of the laser welding robot’s capabilities.
