气电焊是一种高效率易于实现机械化自动化的焊接方法。它是在手工电弧焊、埋弧自动焊广泛应用的基础上发展起来的新工艺。从气电焊发展的趋势来看,在美、苏、日、西德等主要工业发达国家,气电焊发展的比例逐年增大,发展十分迅速。例如西德在1960年所完成的焊接工作量中,手工焊占95.6％,气电焊仅占2％;到1975年手工焊下降到56.7％,而气电焊上升为59.9％;预计1980年后手工焊比例将进一步下降,气电焊比例将进一步上
Gas welding is a high-efficiency and easy-to-mechanize automated welding method. It is in the manual arc welding, submerged arc welding widely used on the basis of the development of new technology. From the trend of the development of gas-electric welding, in the major industrialized countries such as the United States, the Soviet Union, Japan, West Germany and the like, the proportion of gas-electric welding development has been increasing year by year with a very rapid development. For example, in the amount of welding work done by West Germany in 1960, 95.6% of handwork was made by hand and only 2% by gas and electric welding; by 1975, 56% by hand, and by gas-electric welding by 59.9%; handwork was expected after 1980 Welding ratio will further decline, gas welding ratio will be further on
