Problems solved by technology

At present, in the spot welding evaluation process of the plate test, the plate material sheets are overlapped and then welded in a hand-held manner. In this way, the plate material sheets must be pre-fixed before welding, which not only has potential safety hazards and low efficiency, but also The centering of the solder joint position is also difficult to control, which affects the welding quality of the plate, and ultimately affects the spot welding weldability evaluation results of the plate sample

Abstract

The invention belongs to the technical field of plate spot welding weldability evaluation auxiliary testing equipment, and provides a plate sample spot welding clamping and positioning device. A device body (1) of the plate sample spot welding clamping and positioning device is provided with a plate sample groove (2).

Description

technical field [0001] The invention belongs to the technical field of auxiliary test equipment for plate spot welding weldability evaluation, and more specifically relates to a plate sample spot welding clamping and positioning device. Background technique [0002] Spot welding is the main connection method in automobile manufacturing, and it is the key to the safety guarantee of automobile structure. Therefore, in order to meet the mature application requirements of advanced high-strength steel sheet materials in automobiles, it is inevitable to study the spot welding process and performance of sheet materials. The spot welding weldability evaluation of sheet materials is an important part of the sheet material evaluation system. part. In the spot welding weldability evaluation of plate materials, the spot weldability range, shear tensile performance, cross tensile performance and solder joint fatigue performance tests are carried out after the plate material sheets are l...
