电渣堆焊技术堆焊层的增碳作用极小,由于堆焊时无电弧,母材熔深较浅,减少了因低合金钢母材熔化引起的堆焊层增碳作用,可以显著提高堆焊层的耐腐蚀性能;同时,由于电渣焊剂的碱度高,氧化性小,并在焊剂组分中加入某些成分改善熔池冶金物理化学反应,有利于防止某些与氧亲和力强的合金元素的烧损。本文通过对单层带极电渣堆焊用钢带、焊剂及有关工艺的试验研究,进行了冷高压分离器的焊制。
Electroslag surfacing technology surfacing layer carbon addition effect is minimal, due to no arc surfacing, base material penetration shallow, reducing the melting of low alloy steel base metal melting caused by the role of carbon layer can be significantly increased Surfacing layer corrosion resistance; the same time, due to the high basicity of electroslag flux, low oxidation, and add some components in the flux component to improve the physical and chemical reaction of molten pool metallurgy, help to prevent some of the strong affinity with oxygen Alloying elements of the burning. In this paper, a single layer with electroslag welding with a strip of steel, flux and related experimental research, conducted a cold high pressure separator welding.
