Another way of Copper Electrode gas welding, manual carbon arc welding, manual arc welding and manual argon arc another way, the large-scale structure can also take the initiative welding.
(1) copper gas welding
Welding copper is most often used in the docking discussion, lapping discussion and discussion of T to take as little as possible. Welding can take two wires, one wire containing deoxy elements, such as wire 20, 202; another red copper and base metal cutting, take the gas agent 301 as flux. Welding copper to be taken to a neutral flame.
(2) copper manual arc welding
Taken in manual arc welding of copper 107 copper electrode welding core of copper (T2, T3), The edge of the weld should be cleaned before welding. Weldment thickness greater than 4 sister before the welding necessary to preheat, the preheat temperature is about 400 ~ 500 ℃. 107 electrode with Copper Electrodes, the power should be taken to the DCRP.
When they should be short-arc welding, the electrodes are not suitable for lateral oscillation. Electrode for exchanges between the straight-line activities can improve weld forming. Long weld should be taken to gradually retire welding method. Welding rate should be faster. Multi-pass welding, it is necessary to completely remove the slag layer.
Welding should be carried out in well-ventilated places, to provide protection against copper poisoning. The use of flat mallet percussion weld after Welding Electrode  to eliminate stress and improve weld quality.
