Description

Technical Field

[0001] The utility model relates to the field of welding equipment, in particular to a five-axis welding machine. Background Art

[0002] At present, the welding between two or more pipe sets cannot be completed by the welding machines in the prior art. This is because the welding machines in the prior art have fewer degrees of freedom and cannot reach the areas where the two or more sleeve parts are joined, so they cannot be welded. In addition, the welding machines in the prior art can only fix and clamp the sleeve parts at a fixed angle or position, and then weld them through a welding gun with fewer degrees of freedom. On the one hand, such welding machines cannot weld some blind areas due to the fewer degrees of freedom; on the other hand, the sleeve parts are fixed at a certain position or angle, resulting in unstable welding and some welding areas being relatively weak.
