Tips:1.Grease, oxide and other dirt on the surface of the workpiece and solder must be strictly removed before brazing. The best clearance of brazing joint is 0.03~0.075mm
2.Silver phosphorus copper solder, attention to the rapid heating brazing as far as possible, so as to form beautiful brazing joint, if the heating time is too long, or brazing temperature is too high, it is possible to produce pores.
3.Silver phosphorus copper solder does not need welding powder (solder paste) for welding copper, but brazing brass can be matched with welding powder (solder paste), which makes the weld more beautiful after welding. The general weld seam into black after welding and bright gray after pickling.
4.Non-phosphorus solders are generally brass after normal brazing,cadmium-containing brazing solder seam color is red and white, with the increase of silver content, environmental protection solder seam color is more white.
5.Silver Welding Rod is usually used with silver welding powder (silver solder paste) as a flux to help the electrode better melting and penetration into the weld.
