Copper busbar is a kind of conductive, thermal, corrosion resistance, excellent ductility of metal, its strength performance is also very good. Copper busbar is generally known as copper elemental, its texture is tough, soft, has good extension, with rose red metallic luster, after the formation of oxide film, the surface appears purple, Copper busbar is one of them. The welding methods include gas welding, arc welding, hand argon arc welding, hand carbon arc welding and so on.

Gas welded copper busbar

In violet exhaust welding, the commonly used welding method is the joint, and as little as possible to use lap and T-shaped welding. There ARE two different kinds of welding wire to choose from, one is a deoxidized wire, the other is a common copper wire or base wire cutting machine. Adopt neutral flame to carry on copper exhaust welding, use gas agent 301 as flux.

Bar arc welded to copper busbar.

When the copper parts are welded by arc welding, if the thickness of the welded parts is greater than 4 mm, it must be preheated. The adding temperature is usually between 400 and 500℃.  When using short arc welding, the electrode should be moved in a straight line in order to improve the weld forming effect. It is not suitable for lateral swing. If the weld length is large, step back welding method should be adopted to make the welding speed as fast as possible. In the case of multi-layer welding, the slag on the surface of the previous layer must be completely removed before welding the new layer.

Manual argon-arc welding of copper busbar.

When argon arc welding is carried out manually with red Copper busbar, the welding way of welding wire is the same as gas welding, and red copper wire can be used in addition. Before manual argon arc welding, the workpiece edge and wire surface oxide film, oil and other impurities must be thoroughly cleaned mechanically or chemically. If not cleaned up, it will form pores, slag and other defects on the weld.

Manual carbon arc welded copper busbar.

Manual carbon arc welding Copper busbar electrodes have carbon electrode or graphite electrode. The welding wire used for carbon arc welding is the same as that used for gas welding and manual argon arc welding, and the base metal shear strip can also be used, and the flux used is the same as that used for gas welding.
