焊接环鏈(以下簡称錨鏈)在工业上用途很广。过去煤矿用的刮板运輸机一向沿用模鍛可拆卸式鏈。随着煤炭工业运輸机逐漸向运輸量增大及机身加长的方向发展,模鍛鏈已不能滿足要求,因此各工业先进国家已大量采用錨鰱来代替模鍛鏈。 錨鏈的制造工艺根据对焊方式不同而分为两类:閃光对焊和电阻对焊。閃光对焊时,每个鏈环由两个U形半环合成,用閃光对焊法一次焊完两个焊口,編成链条的过程也在焊接工序中逐个进行。而电阻对焊时,焊前
Welding chain (hereinafter referred to as anchor chain) is widely used in industry. In the past, scraper conveyors for coal mines had always used forged removable chains. With the coal industry transport aircraft gradually increased traffic and the body lengthened the direction of die forging chain has been unable to meet the requirements, so the advanced countries have adopted a large number of anchor silver carp instead of die forging chain. Anchor chain manufacturing process according to different butt welding methods are divided into two categories: flash butt welding and resistance butt welding. When flash butt welding, each link is composed of two U-shaped half-rings, one soldering two soldering joints with a flash butt welding method, and the process of composing the chain is also carried out one by one in the welding process. The resistance of the welding, welding before
