在一般工业国家中,约有30%的钢材经过焊接加工制为成品,因而消耗大量电能。本文的目的在于系统地研究、分析占焊接工作量90%左右的交流手工电弧焊接、直流弧焊发电机手工焊接、弧焊整流器手工焊接、埋弧自动焊接、半自动二氧化碳气体保护焊接五种主要弧焊方法的耗能指标,从而有助于正确选择焊接方法,发展节能焊机,以达到节能的目的。 In the general industrialized countries, about 30% of steel is processed into finished products by welding, thus consuming a large amount of electric energy. The purpose of this paper is to systematically study and analyze five major arcs of AC manual arc welding, DC arc welding generator manual welding, arc welding rectifier manual welding, submerged arc automatic welding and semiautomatic carbon dioxide gas shielded welding which accounts for about 90% of the welding workload Welding method of energy consumption indicators, which will help the correct choice of welding methods, the development of energy-saving welding machine, in order to achieve energy-saving purposes.
