Brazing metal hose connector structure has the following characteristics

Brazing metal hose connector structure has the following characteristics:
Brazing seam wall shape is more complex. A corrugated thin steel net. Shown in Figure l . In order to ensure the tightness of brazed joints and carrying capacity , for brazing high quality requirements , and in the production of sufficient stability. Because corrugated hose and fine steel mesh thin thin, fast flame with oxygen B manual Hydraulic pipe fittings cause overheating. Bitter than 830C is generated stability of chromium and titanium oxides is difficult to remove , the solder is almost impossible , so the required soldering process to prevent oxidation. In the welding production practice . Due to its special structure and unfavorable factors, using oxygen B brazing often difficult to achieve faster design and process requirements. In order to properly solve this problem. We use Arc Brazing new technology. That is carried out under an inert gas protection pull arc melting brazing , MIG arc in the workpiece and is surrounded by protective gas .hydraulic hose assemblysaterial as the arc electrode . Continuously fed from the torch brazing zone , forming the weld brazing filler metal . Cast arc melting brazing material is characterized by a low melting point solder ( 2 silver solder melting point of 860 ~ 900 "C), high mechanical strength , the weld heat affected zone is small brazing without the use of solder may not have a corrosive effect . Welding not after cleaning . device operation side cartridges. cartridges in automated.
