焊接自动化和焊接机器人能提供稳定的焊接质量，减轻工人的劳动强度，提高生产率，降低成本，是若干年来人类干方百计追求的目标。日本早在70年代就已将点焊机器人引进生产线，而弧焊机器人由于其复杂性，在生产中的应用要比前者晚得多。但到了80年代，日本弧焊机器人的使用开 Welding automation and welding robots can provide stable welding quality, reduce the labor intensity of workers, increase productivity and reduce costs, which is the goal pursued by human beings in the past few years. Japan introduced spot welding robots into production lines as early as the 1970s, and arc welding robots are much later in production due to their complexity. But by the 1980s, Japan’s use of arc welding robots was on
