Among them, the restraint frame includes a first horizontal portion, a first vertical portion and a second vertical portion located on both sides of the first horizontal portion, a second horizontal portion connected to the first vertical portion, and a third horizontal portion connected to the second vertical portion. One side of the first horizontal portion is attached to the fixture base plate, and the other side is attached to the toothed pad. And a gap of a preset width is provided between the second horizontal portion and the third horizontal portion. The first vertical portion is provided with a first bolt assembly, the second vertical portion is provided with a second bolt assembly, the second horizontal portion is provided with a third bolt assembly, and the third horizontal portion is provided with a fourth bolt assembly. The first to fourth bolt assemblies are used to fix the workpieces to be welded.

[0003] In the process of implementing the above embodiments, it is found that there are at least the following problems in the related art:

[0004] The clamping effect of the first bolt assembly and the second bolt assembly on the restraint frame is used to subject the workpiece to be welded to a high degree of clamping force, thereby completing the welding cold crack test of the tailor-welded plate. However, the distance between the first bolt assemblies on both sides and the second bolt assemblies on both sides cannot be controlled, so only plates of a specific size can be clamped. When the size of the plate is small or too large, the plate cannot be clamped.
