Description
HZ-QJ301 Copper brazing flux paste
1. Description
Fluxes are chemical compounds applied to the joint surfaces before brazing.
Their use is essential in the soldering/brazing processes. Heating a metal surface accelerates the formation of oxides, the result of chemical combination between the hot metal and oxygen in the air. This oxide layer has to be removed before brazing, and the formation of a new oxide layer has to be prevented or they will inhibit the filler metal from wetting and bonding to the surfaces.
Function:
1.Melting, covering, isolating, preventing oxidation
2.clean the surface of weld
3.Participation in flow brazing/puddle welding
Notice:
(1) Clean oils, oxides and other contaminants of brazing components and solder surface .
(2) Before welding,Workpiece must be preheated to about 500 degrees, Electrode coated with an appropriate amount of brazing flux .
(3) After welding, Cleaning welds, prevent corrosion of residues solder flux.
(4) It should be stored in a dry place, against damp.
Welding operation:
Mix the welding powder with pure water to paste, apply paste to the mouth of welding workpiece, or pre-heating the brazing and soldering alloy first, use the brazing and soldering alloy stick with the welding powder, the welding gap could not too big, it is normally 0.01-0.05mm.
In the flame brazing, usually to use neutral welding, in the operation, should to avoid to use the flame to heat the brazing & soldering alloy and the welding powder
Advantage:
1. low melting temperature.
2.good fluidity
3. little deformation for parent material
