高生產率的自動焊接方法,已逐漸開始在我国应用。研究薄板的熔剂层下自動焊接的方法,乃是目前許多工業部門中所等待解决的問題。現在介紹近年來苏联焊接工作者在这方面工作的成果。苏联学者很早就从事於薄熔剂层下自動焊的研究。远的1946～1947年,柏統院士在实验室中研究了用4公厘粗的焊絲,在熔剂压下自動焊接厚度为2～3公厘的鋼板的規范,但很少獲得令人滿意的結果,僅僅只有緊貼着銅垫与焊藥垫的薄板的焊接,才得到較为令人滿意的結果。过去对於薄板的焊接,多半採用在有焊藥垫的电磁平台上、在銅垫或焊藥垫上、以及在永久襯垫上進行單面自動焊。这些方法無論在生產率上或設 High productivity of automatic welding methods, has gradually begun to apply in our country. Research on the automatic welding of sheets under the flux layer is a problem awaiting solution in many industrial sectors. Now I will introduce the achievements of Soviet welding workers in this field in recent years. Soviet scholars have long been involved in the study of automatic welding under thin flux layers. Far from 1946 to 1947, academicians in the laboratory studied the use of 4-mm thick wire in the laboratory, automatic welding of flux at a thickness of 2 to 3 mm thick steel plate specifications, but rarely get satisfactory As a result, only a close contact with the copper pads and welding pads sheet welding, get more satisfactory results. In the past, welding of thin plates was mostly done on a soldered electromagnetic platform, on a copper pad or flux pad, and on a permanent pad. These methods are in terms of productivity or set
