Product Description: Copper-aluminum-stainless steel welding wire seam repair in Wuxi 1. Good welding effect: its welding effect is full and smooth! With the help of internal powder. It has a low melting point, good fluidity, hardness and toughness, and good sealing. No need to use other flux powder 2. Direct use: any flux is really needed, open the package for use! very convenient! Easy to solder. 3. Welding: first use sandpaper to polish the brass and aluminum pipe welding parts (the paint, oxide, oil, etc. on the metal surface must be cleaned), move the welding torch to evenly heat the welded parts, and then continue to use the welding rod to be welded when the temperature rises to At 360 degrees, the copper-aluminum electrode melts and evenly enters the joint.
