卡套式接头具有较大的强度,但是如果在高温的环境中使用,那么卡套式接头就会出现脆化现象,为了避免这个现象的发生,我们在使用卡套式接头时需要尽量避免在高温环境中使用。

    卡套式接头指两个或两个以上零件要用焊接组合的接点。或指两个或两个以上零件用卡套方法连接的接头,包括焊缝、熔合区和热影响区。在卡套发生熔化凝固的区域称为焊缝,它由熔化的母材和填充金属组成。

卡套式接头

    卡套式接头的脆化现象,卡套式接头的强度并不低,但是有时在使用不到几个月就会延焊缝或近缝区发生脆断,这种现象在极端温度环境下更易出现。由于不锈钢的焊缝在高温加热一段时间后,出现冲击韧性下降的现象称为脆化。

青海快3The sleeve joint has great strength, but if it is used in the high-temperature environment, the sleeve joint will appear embrittlement. In order to avoid this phenomenon, we need to avoid using the sleeve joint in the high-temperature environment as much as possible.

A bayonet joint is a contact where two or more parts are to be welded together。 Or of two or more parts connected by a bayonet, including welds, fusion zones and heat affected zones。 The area where the sleeve is melted and solidified is called the weld, which consists of the molten base material and the filler metal。

Bayonet joint

The embrittlement of the sleeve joint is not low in strength, but sometimes it will occur in the weld or near seam area within a few months after use, which is more likely to occur in extreme temperature environment. Because the weld of stainless steel in high temperature heating for a period of time, the impact toughness decline phenomenon called embrittlement.
