什么是卡套接头的脆化现象

[导读]: 卡套式接头指两个或两个以上零件要用焊接组合的焊接点。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。

什么是卡套接头的脆化现象,为何卡套接头会出现脆化现象,面对这种现象,我们要如何避免,接下来,针对这些问题,小编为您进一步介绍,关于什么是卡套接头的脆化现象的相关内容,希望对您有所帮助。

What is the embrittlement phenomenon of the bayonet joint? Why does the bayonet joint appear embrittlement? How can we avoid this phenomenon?

卡套式接头指两个或两个以上零件要用焊接组合的焊接点。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。

Bayonet joint refers to the welding point of two or more parts to be combined by welding. Or refers to two or more parts of the joint with the method of bayonet, including the weld, fusion zone and heat affected zone. The area where the jacket melts and solidifies is called a weld and consists of a molten base metal and a filler metal.

那么什么是卡套接头的脆化现象: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。

Then what is the brittle phenomenon of the bayonet joint: the strength of the bayonet joint is not low, but sometimes in the use of less than a few months will be along the weld or near the seam brittle fracture, this phenomenon is more prone to occur in the extreme temperature environment. As the welding seam of stainless steel is heated at high temperature for a period of time, the phenomenon of impact toughness decline is called embrittlement.

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。

The bayonet type joint has great strength, but if used in high temperature environment, then the bayonet type joint will appear embrittlement phenomenon, in order to avoid this phenomenon, we need to try to avoid the use of bayonet type joint in high temperature environment.
