Abstract

The invention relates to a kind of bipolar latent arc welding method with large heat capacity which is best used for single face, signal channel welding in corner connector welding for steel with thickness more than 50 mm and without increasing the welding power. The diameter of wire solder of advanced electrode is around 4.8 mm to 5.6 mm. The current density of advanced electrode is set to 80 to 100 A/mm<SP>2</SP> and the voltage of advanced electrode is set to 42V to 55V. The distance between the advanced electrode and after electrode is set to 50 mm to 90 mm as the welding conditions. Furthermore, the welding flux employs the SiO2 of 10 to 30% by weight; MgO of 5 to 30%; Al2O3 of 2 to 20%; CaO of 2 to 10%; metal iron powder of 10 to 40%; metal component selected from more than one of silicon, manganese, titanium and aluminum, etc. as total weight of 1 to 10%; as a better welding flux.
