利用建立的冷金属过渡(Cold Metal Transfer,CMT)焊接快速成形系统,建立焊道搭接和层间高度计算模型,并对相邻焊道最优搭接率和最优层间高度进行计算、验证及分析。结果表明:在理想状态下,当相邻焊道中心距(L)为熔宽(W)的2/π倍,层间高度h为余高H的2/π倍时,有利于提高成形零件的表面平整度;采用适应性的参数选择可以获得更为理想的成形效果。 The rapid lapping system of Cold Metal Transfer (CMT) was established to establish the model of lap lapping and inter-floor height calculation, and the optimal lap-overlap ratio and optimal inter-floor height of adjacent lap were calculated. Verification and analysis. The results show that when the center distance (L) of adjacent weld bead is 2 / π times of the weld width (W) and the height h of the ply is 2 / π times of the residual height H in the ideal state, the forming part The surface smoothness; using adaptive parameter selection can be more ideal forming effect.
