Here are some of the features and functions of a gantry-type multi-axis welding robot: Multi-axis degrees of freedom: Gantry-type multi-axis welding robots typically have multiple degrees of freedom, allowing them to move and rotate in three or more directions to achieve a variety of welding positions and angles.

[0003] Gantry multi-axis welding robot, also known as robot walking axis or robot 8th axis, is suitable for machine tool workpiece loading and unloading, welding, assembly, spraying, inspection, casting, forging, heat treatment, metal cutting, handling, palletizing and other tasks. A robot walking system can realize multi-station handling, and a robot can realize automated processing flow with multiple processing equipment.
