怎样才能保障焊接冲压弯头的质量

Classification:Industry NewsPublished on:2021-11-30

上海若松金属制品有限公司终年自主出产直销弯头、有缝弯头,无缝弯头、国标弯头等系列产品,是一家大型的弯头批发厂家,河北孟村管件厂家者,我公司产品规格完全,质量确保,可依照需求定。


现在市场上的冲压弯头多为高压厚壁,中频无法推制的才会用冲压工艺。


冲压弯头的焊接与焊后:


冲压弯头进行焊接时,经过加热会开释出碳化物,受到重复加热析出碳化物,开释的碳化物会影响冲压弯头的功能,下降性和力学功能。以上是关于在运用冲压弯头时需求留意的事项,需求依照的方法和事项进行运用,确保其杰出的运用价值和功能。


冲压弯头焊后硬化性较大,容易产生裂纹,在焊接时选用不同的焊条进行焊接,确保焊接的冲压弯头的质量。若选用同类型的铬冲压弯头焊条焊接,进行300℃以上的预热和焊后700℃左右的缓冷处理。若焊件不能进行焊后热处理,则应选用铬镍冲压弯头。不同品种的焊条在运用中具有不同的功能和特点,在运用中依照相应的需求选用,保障焊接的冲压弯头的质量。
