The results show that beam offset can greatly affect the macro performance of Laser tailor-welded weld , then affect the cuppingTest value and tensile strength unconspicuous.
结果表明，光束偏移量对激光焊缝宏观形貌有很大的影响，而对焊缝杯突值及抗拉强度无明显影响。

According to GB4156-84 "the method of metal cuppingtest", develop the cupping grips that can be used in servo universal testing machine and computer control pressure testing machine.
Using statistical backward elimination method, the mathematic model was established for the relativity between cuppingtest value (ie) and mechanical properties of 9 kinds of steel sheet.
