[钢筋]焊接接头强度试验
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.
选用正交试验设计方法确定Fe-Mn-Si形状记忆合金激光双面焊接的最佳工艺参数,以焊接后试样的抗拉强度作为评定焊接性能的指标。
