Copper Zinc Filler Metal Brass Brazing Rod Alloys Length As
Brass welding rod refers to the application of brass welding
materials , suitable for oxygen-acetylene , TIG , MIG welding ,
widely used in automotive , shipbuilding , electrical and other
manufacturing industries . Sultable for gas welding and carbon arc
welding of brass , also braze welding of copper,steel and cast iron
The welding of brass brazing rod is more difficult than that of
steel, and it is prone to defects such as metal oxidation, metal
element evaporation, porosity, cracks and deformation, so attention
should be paid when welding .
Internationally used grades are SW221 , HS221 , BCu60ZnSn(Si),
regular diameter size are 2.0mm ,5.0mm , and so on . Length are
500mm , 1000mm. brass brazing alloy is composed of copper-zinc
Precautions for welding :
1 . The thermal expansion coefficient of copper is large , and a
large shrinkage stress occurs during solidification , which causes
cracks and deformation . Therefore , the assembly gap should be
wide , and the bevel angle should be large . Multiple temporary
spot welding can also be used . In order to obtain a good weld, the
oxides , grease and other dirt on the edges to be welded should be
removed before welding .
2 . Due to the particularly high thermal conductivity of copper and
copper alloys , it is necessary to preheat and weld with a larger
3 . When brazing brass to brass welding operations should be
performed in a place with air circulation or artificial ventilation
to prevent copper poisoning . Welding quality After welding , a
flat-head hammer is used to hammer the weld to eliminate stress and
refine the grain .
|Brass Welding Rod Advantages|
brazing copper to brass hvac brazing rod has good fluidity and
brass welding wire has good plasticity and corrosion preventive
brass to copper soldering has high purity , less impurities
brass solder wire has low temperature, good fluidity.
Brass filler rod has best quality and factory price
|It can reduce melting point, improve plasticity of brazing alloy
and wettability of copper, as well as improve brazing alloy’s
strength and toughness.|
