在我国,没有一个工業部門不在为着排斥手工焊接,以及以現代化的自动与半自动弧焊机的工作來代替繁重的生产率低的手焊工人的劳动,而进行着尖銳的斗爭。这个斗爭已取得了显著的成就。在应用熔剂層下自动焊接的規模和技术水平方面,苏联在欧洲是占第一位的。而熔剂層下焊接目前已成为許多重工業部門、运輸工業和建筑工業技术进展上的有力的工具。我国在世界上第一个創造并在生产上推广了新的厚金屬的电渣焊方法,并發展了金屬和合金的气—电焊接的各种工艺方法。在新的、利用环形变压器的接 In our country none of the industrial sectors is struggling sharply to exclude manual welding and to replace the laborious manual labor of low-productivity hand-welders with the work of modern automatic and semi-automatic arc welders. This struggle has made remarkable achievements. The Soviet Union ranks first in Europe in terms of the size and technical level of automatic welding under the flux layer. Welding under the flux layer has now become a powerful tool for technical progress in many heavy industries, transport and construction industries. In the world, our country was the first to create and promote a new electroslag welding method for thick metal in production and to develop various gas-electric welding processes for metals and alloys. In the new, use toroidal transformer connection
