FB301S-2 braze powder

Preparation before welding: welding surface before welding should be clean, in the absence of surface oxides and grease braze welding can achieve the best results. Flame brazing, usually appropriate to neutral flame. Welding operations: the solder powder into a paste with hot water or heating after the first solder solder powder using glue. The operation should try to avoid direct flame heating solder and flux. After the welding process: glassy residue after welding. General mechanical polishing method to clean up. The most convenient way is: to be solidified hot solder into the water quenched. Jet burst effect by the vaporization of water molecules to make the slag quench cracking off, and while the soluble portion of the residue is dissolved happened. But when put into water weldment temperature is not too high to avoid deformation of the weldment cracking. Application: radiator, bicycles, fitness, refrigeration parts, auto parts, jewelry, electrical appliances, hardware tools. Storage storage: Store in a cool dry place. Use: with copper-based, nickel-based brazing copper and copper alloys, carbon steel, alloy steel, stainless steel, tungsten carbide and other materials. It can be used for furnace brazing, flame brazing, high-frequency brazing. Physical state: white powder, particle size ≤150μm, density: 1.2-1.3 g / cm3.
