Flame brazing is to apply can light gas to heat

Flame brazing is to apply can burn gas (the model steam that includes liquid fuel) blow undertake heating with the blaze after air or pure oxygen light. Flame brazing because equipment brief, antecedents burning gas wide, flexibility is big, apply consequently very wide.
Flame brazing place uses solder fire but so general gas welding fire, also but so fire of solder of appropriative drill rod. The characteristic of fire of solder of special drill rod is blaze compares lax, heat meeting market rate is inferior, heat consequently evener. Drill rod solder compares great work or the fire of solder of special drill rod of much blaze nozzle can be used when mechanization flame brazing.
Place of solder of chaffy dish drill rod uses can burn gas but so benzine of acetylene, propane, petroleum gas, pulverization, gas etc. Support combustion gas is oxygen and constrictive gas. Heat scope is very broad, hundreds degrees of from alcohol blowtorch more than 3000 ℃ to oxygen acetylene blaze. Blaze has two structures, outer the coronal shape blaze of baby blue is oxidizing flame, burn complete, temperature is highest, oxygen boosting, excessive heat to make workpiece metal surface oxidizes simply: The blaze heart with blue-black lining is reductive blaze, temperature is inferior, anoxic, rich carbon monoxide, can safeguard a metal to avoid at oxidation. Can light gas to burn the product is CO2 and high temperature water vapour (oxyhydrogen blaze wants vapor only) , no matter be brazing flux,still be drill rod makings, abstain from high temperature water vapour should ponder over this one element.
Oxygen acetylene blaze is the most commonly used blaze, because blaze temperature is high, and temperature of drill rod solder is low much. Consequently the outer flame of commonly used blaze heats, the temperature as a result of this area blaze is low and volume is large, heat evener. Apply neuter blaze normally or subtle cross acetylene blaze.
Should heat temperature does not request too tall when, can replace oxygen with constrictive air, with propane, petroleum gas, pulverization benzine replaces acetylene. The temperature of these blaze is inferior, and need not the blaze of acetylene won't pollute brazing flux again, apply to drill rod solder to compare little work and aluminium and aluminium alloy.
When flame brazing, besmear brazing flux solution beforehand in contact apparently heat club of drill rod makings first probably, touch with brazing flux, take heated contact appearance again. Drill rod expects but beforehand device or craft send into. Shi Yingxian of drill rod solder heats workpiece equably temperature of drill rod solder, add drill rod makings again next, otherwise drill rod expects cannot even ground fill is interstitial. About beforehand the connect that buy drill rod expects, also should heat first workpiece, because blaze and drill rod makings are felt directly,prevent, make its fuse prematurely, when undertaking drill rod solder with solder, still can use blowtorch to heat.
