Detailed Product Description: | Foshan Yihong Welding Co., Ltd. to provide you with a Cu-Al solder, the copper and aluminum welding filler metal mainly for copper and aluminum brazing (welding). The copper and aluminum welding filler metal with a built-flux; fluidity; brazing temperature is low; welding high strength characteristics. The copper and aluminum welding filler metal has been used in air conditioning refrigeration copper and aluminum between the brass and aluminum welding, refrigerator between brass and copper and aluminum welding aluminum, copper transformer between the copper and aluminum and aluminum welding the motor industry, copper and aluminum wire and aluminum welding between the aluminum industry has been changed so copper mature application. (Air conditioning copper and aluminum welding, copper and aluminum welding refrigerators, transformers, copper and aluminum welding, electrical copper and aluminum welding, copper and aluminum welding transformer, the two devices copper and aluminum welding, copper and aluminum welding) Contact: Miss Yang. Tel:. Copper and aluminum welding joint guidance of professional operation In addition, I also specifically provide you with professional methods of operation One, materials and tools: Copper and aluminum electrodes (private), welding tools, wet towels, 600 # emery cloth. Second, the operation process: 1, the preparation of materials and tools. 2, the welded joint clean and polished with 600 # emery cloth. 3, the refrigeration evaporator back into the freezer evaporator tube connecting tube of about 8-10mm. 4, the freezer may be baked into the bile around the fire place where the wet towel. 5, lit torch, the flame adjusted to Wei Huo, uniform heating at the solder joints (such as: copper and aluminum welding, solder joints can not be directly heated, the first heat from the solder joint 3CM Department brass, the use of the heat transfer of copper tubes heating, heated to solder copper pipe at the reddish, you can even add solder; such as: aluminum to aluminum welding, heating the first end-to-whitish thick tubes can even add additional solder.) 6, welding has been completed, the system filled 8MPA nitrogen leak, leakage, after confirming that no welding, taking the time to let go of nitrogen perfusion, detection test machine. Third, pay attention: 1, the torch flame can not be too long and must be heated by Wei Huo, or easily melt aluminum. 2, the liner must be placed wet towels to protect the place, because the weld is very narrow space, so be sure to pay attention to the protection of the refrigerator. 3, one-time successful welding better, due to low melting point tubes, the second re-heating, the tubes easily deformed. 4, the welding time can not be too long, too long because of low melting point, easily lead to melting or thinning of the tube wall to suppress easily leak. 5, the welding is completed, we have to wait two or three minutes before contact with the cooling tubes, or leaky joints If you have any of the unknown, as possible call:, Miss Yang. |
