1·The results show that beam offset can greatly affect the macro performance of Laser tailor-welded weld , then affect the cupping Test 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。

2·According to GB4156-84 the method of metal cupping test, develop the cupping grips that can be used in servo universal testing machine and computer control pressure testing machine.

根据GB4156 - 84《金属杯突试验方法》，研制在伺服万能试验机或微机控制压力试验机上应用的杯突试验夹具。

3·Using statistical backward elimination method, the mathematic model was established for the relativity between cupping test value (ie) and mechanical properties of 9 kinds of steel sheet.

应用数理统计中“后向消去法”建立了九种板料杯突值ie与力学性能间的相关性数学模型。
