焊接英语简介

In 1953 Lyubavskia and Novoshilov announced the use of welding with consumable electrodes in an atmosphere of CO2 gas. The CO2 welding process immediately gained favor since it utilized equipment developed for inert gas metal arc welding but could now be used for economically welding steels.the co2 arc is a hot ace and the larger electrode wires required fairly high current.efforts were made to make the process more acceptable for the welder and this in turn led to smaller diameter electrode wires and refined power supplies.the outcome of this development was the short circuit arc variation which was known as Micro-wire,short arc,and dip transfer welding,all of which appeared late in 1958 and early in 1959.this variation of the process allowed all-position welding on thin material.it soon became the most popular of the gas metal arc welding process variations.

Lyubavskia宣布在1953年和Novoshilov焊接的应用与耗材电极在大气层的二氧化碳。CO2焊接过程得到支持,因为它立刻使用惰性气体设备研制金属电弧焊接但现在能够被用于经济焊接钢。电弧是一个热的co2空间和较大的电极导线要求较高的电流。努力使这个过程更可接受的对焊机,这也导致电极导线较小直径和雅致的电力供应。结果,这次的发展就是短路电弧变异,这被称为Micro-wire、短弧,短路过度焊接,晚些时候发表在1958年和1959年初。这个变化过程的全位置焊接允许对薄材料。它很快成为最热门的金属电弧焊接过程中气体的变化。

The electro-slag welding process was announced to the Western world by the Russians at the Brussels World's Fair in Belgium in 1958.it had been used in the Soviet Union since 195lbut was based on work done in the U.S.A.by R.J.Hopkins,who was granted patents in 1938 and 1940.the process and its variation,using a consumable guide tube,have become popular and are widely used for welding thicker materials.electro-slag uses equipment similar to submerged arc welding but there is no arc after start up.

焊接过程的electro-slag西方世界宣布俄国在布鲁塞尔世界博览会在1958年比利时。它已经被应用于苏联lbut是基于自195年以来所做的工作在U.S.A.by国立霍普金斯,谁被授予专利在1938年和1940年。过程及其变化,使用一个消费品引导管,已经成为流行,广泛用于焊接较厚的材料。electro-slag用埋弧焊设备相似但没有弧后开始运行。
