What Are The Welding Difficulties Of Copper And Brass Strip

What are the welding difficulties of copper and brass strip

What are the difficulties of copper and brass strip welding? Below, the staff of copper limited company to tell you a simple say!

1. The thermal conductivity of copper strip is much greater than that of steel. Welding heat is more likely to lose, more likely to cause excessive internal stress, resulting in welding deformation and other welding problems. Therefore, welding requires heat concentration. Welding methods include tungsten argon arc welding and plasma welding. In addition, proper preheating should be carried out before welding. Small amounts of brazing should not be preheated as long as they are not less than zero.

2. No matter what kind of copper and brass strip, white smoke will be produced during the welding process, that is to say, although zinc is not a heavy metal, if the welding site is poorly ventilated, white smoke will irritate the respiratory system, especially the lungs, or if you do not wear a mask, you will fall down after 30 minutes of work.

3, is the welding material, the material should be the same as the base material. If only ordinary welding, you can use φ2.5-φ4 ordinary copper alloy wire.

4, the liquid surface tension coefficient of copper strip is only 70% of iron. It is easy to roll the molten pool during welding, and the roots will not melt. To solve this problem, you must start with the same welding method and then finish. At the beginning of welding, the welding Angle (10°-30°) is not appropriate, but only this Angle can solve the melting problem of tungsten argon arc welding.

5. If you want to obtain high quality welding, you are not afraid of spending money. It is recommended to use very inert gas shielded flux cored wire, which has a very good effect, but the cost is very high.

In short, copper strip busbar welding is a high heat, small Angle and high protection job.
