1, the operating temperature and the use of tools
1) Operating temperature: 420 ℃ ~ 480 ℃
2) the use of tools: oxygen acetylene Welding Wire China carbon liquefied petroleum gas welding resistance welding

2, parts cleaning:
Welded to the metal surface before the paint, oxide, oil, and so clean, in order to protect
Permit the welding quality. As paint, oil will be carbonized when heated, the metal surface to form a membrane
, While the solder layer in this membrane can not flow, as well as corrosion of the solder can not be in a form on the surface
Into the connection.

3, with the workpiece and the appropriate clearance:
Copper and aluminum brazing can be used the way lap, aluminum and aluminum brazing can be used lap or butt
The way. Typically, you can simply put a piece on top of another piece can be.
Metal to metal contact with the surface is required for brazing gap. If the component is more complex
, You can use special fixtures. Brazing must ensure that they are in the correct position,
But also to ensure that they are in the entire heating and cooling process is always able to maintain the correct position.

4, the workpiece welding:
When the fixed workpiece, the workpiece can be directly heated soldering temperature is about 420 ℃ ~ 480
℃, the metal components should be heated as evenly as possible, you need to do is carefully hand-held Welding Rod Supplier

Take the wire connections, the heated soldering temperatures will melt away as part of the component wires, and these
Melting of the wire is immediately adsorbed by capillary action and spread to the entire connection area. The flow of solder
Very strong, so you can easily get high-quality weld.
