目前,国外普遍采用的闪光焊机,具有焊接速度快、焊缝质量好、生产效率高等特点,是机械液压电器和自动控制的综合产品,已成为锅炉管子焊接中不可缺少的关键设备。然而,在我国锅炉行业中,大多数仍采用苏联五十年代的闪光焊机对管子进行焊接,由于这种焊机使用年限过长,调整机构刚性差、焊缝错边超差严重、调整时劳动强度过大等缺点,严重影响着焊接质量。为此,我们借鉴国 At present, flash welding machines commonly used abroad have the characteristics of fast welding speed, good weld quality, and high production efficiency. They are mechanical hydraulics and automatic control products. They have become indispensable for welding boiler tubes. However, in China’s boiler industry, most of the flash welding machines of the Soviet Union in the 1950s still used to weld the pipes. Due to the long service life of the welding machine, the rigidity of the adjustment mechanism is poor, and the misalignment of the welding seam is severe. The disadvantages such as excessive labor intensity seriously affect the quality of welding. To this end, we learn from
