為什么冷作鈑金加工要盡可能減少焊接呢？

冷作鈑金加工的工件具有質(zhì)輕、強度高、加工簡單等特點，因此被廣泛地應用，但在加工的過程中，冷作鈑金要盡可能地減少焊接，這是什么呢？冷作鈑金加工顧名思義，不需要加熱處理，而焊接就是屬于熱加工。

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.

冷作的鈑金材料在焊接后會引起變形，不僅焊接表面處理不美觀，而且影響生產(chǎn)效率，所以就可以通過改變加工工藝來代替焊接，比如沖壓。

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.

鈑金沖壓出來的工件不僅美觀，而且不易變形，但需要制作簡易的模具。

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，對于受力較小或僅起鏈接作用的焊縫,可采用間接斷焊代替連續(xù)焊；或者是利用鉚接來替代焊接,省時又美觀。

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.
