They were then loaded on a tensile machine ( Instron 1122) for slow-pulling, fast-pulling experiment and reciprocating fatigue test at 20N load peak value separately.

将其随机分成三组，在Instron1122拉力实验仪上分别进行慢拉、快拉和20N峰值负荷条件下的反复疲劳实验。

Orthogonal experiment design method is used to determine the optimum laser double-side welding parameters. The tensile strength of the retro-welding samples is used as the indicators of evaluating laser welding performance. The tensile and bending fatigue test are used to study the mechanical properties of welded joint.
