spotweld

1.The effect of the mesh density, the change of dynamic plasticity property of mild steel with strain rate and the spotweld mechanical property on the simulation results is analyzed.

分析了网格密度、身低碳材料塑性特性随应变率变化及焊点力学特性因素对仿真结果影响。

2.To solve the problems of low quality, low efficiency and high cost of steel mesh reinforcement used in the mines, one kind of special spotwelder was developed.

摘要为解决矿山筋网架生产过程中出现产品质量差、效率低、成本高等问题，研制出一种专筋网架焊机。
