我厂在制造厚板結构产品时,因只有5毫米LlM-7粗焊条,而大部分电焊机功率都很小,造成焊接困难和質量不好。后來采用双把焊方法解决了这一关鍵。双把焊接法就是用两台10仟伏安小功率电焊机,焊工双手各拿一把焊钳进行焊接。电焊机二次空载电压要相同,焊接电流相差不得太大,否則造成浪费。把綫和地綫極性应相同。接綫方法 I plant in the manufacture of heavy plate products, because only 5 mm thick LlM-7 electrode, and most of the welding power is very small, resulting in difficult welding and poor quality. Later, double-soldering method to solve this key. Double welding method is to use two 10 kVA low-power welder, welder hands holding a welding clamp for welding. Welding voltage to the same secondary load, the welding current difference should not be too large, otherwise resulting in waste. The polarity of the line and ground should be the same. Wiring method
