Welding sequence of red copper pipe and problems needing attention Generally, 50%, 45%, 35% or 25% silver electrodes shall be used for the welding of copper pipes, which shall have good fluidity and the help of flux. The flux used shall be flexible mixture or powder, carbonization flame for copper pipe welding. Welding sequence of [...]
Air Conditioning Copper Pipe Welding Experience: Silver welding is generally used for copper pipe - copper pipe welding, and the silver content of silver electrode is 25%, 15% or 5%. Copper phosphorus series electrodes can also be used. They all have good fluidity and do not need flux. Copper pipe is an important raw material [...]
Copper strip degreasing methods include solvent degreasing, alkali degreasing, ultrasonic degreasing, high-pressure hot water degreasing, electrolytic degreasing, etc. 1. Solvent degreasing The degreasing solvent is used to dissolve the oil on the strip surface and collect it into a container. The volatile solvent is volatilized, collected and reused, and the pollutants are separated from the [...]
