为什么冷作钣金加工要尽可能减少焊接呢？

冷作钣金加工的工件具有质轻、强度高、加工简单等特点，因此被广泛地应用，但在加工的过程中，冷作钣金要尽可能地减少焊接，这是什么呢？冷作钣金加工顾名思义，不需要加热处理，而焊接就是属于热加工。

Cold-working sheet metal parts have the characteristics of light weight, high strength and simple processing, so they are widely used. But in the process of processing, cold-working sheet metal should reduce welding as much as possible. What is this? Cold sheet metal processing, as the name suggests, does not require heat treatment, and welding is heat processing.

冷作的钣金材料在焊接后会引起变形，不仅焊接表面处理不美观，而且影响生产效率，所以就可以通过改变加工工艺来代替焊接，比如冲压。

Cold-working sheet metal material will cause deformation after welding, not only the welding surface treatment is not beautiful, but also affects the production efficiency, so can be changed by processing technology to replace welding, such as stamping.

钣金冲压出来的工件不仅美观，而且不易变形，但需要制作简易的模具。

The workpiece stamped out of the sheet metal is not only beautiful, but also difficult to deform, but it needs to make simple dies.

另外，对于受力较小或仅起链接作用的焊缝,可采用间接断焊代替连续焊；或者是利用铆接来替代焊接,省时又美观。

In addition, indirect break welding can be used instead of continuous welding for welds with less stress or only linking effect, or riveting can be used instead of welding, which is time-saving and beautiful.
