电弧焊和电弧切割近几年来,电弧焊仍然是大多数国家机器制造、建筑、运输等部门采用的主要焊接方法。据报导,1968年苏联电弧焊在全部焊接工作量中约占63%,美国占48.8%。日本电弧焊占的比重也很大,从1958年到1968年的十年内,焊条消耗量增加了三倍。美、苏、英和加拿大等国,1966年电弧焊的电源设备和自动、半自动焊机,在焊接设备总数中,分别占50～70%和4～6%。
Arc Welding and Arc Cutting In recent years, arc welding is still the main method of welding used in most countries for machine building, construction and transportation. It is reported that in 1968 Soviet Union arc welding accounted for about 63% of the total welding workload, the United States accounted for 48.8%. Japan’s share of arc welding is also significant, from 1958 to 1968, ten years, the electrode consumption increased threefold. The United States, the Soviet Union, Britain and Canada and other countries, in 1966 arc welding power supply equipment and automatic, semi-automatic welding machine, welding equipment in the total, accounting for 50 to 70% and 4 to 6%.
