Silicon Bronze: Mig Welding Process (GMAW)

Application
Use for welding of Silicon Bronze Copper, or Aluminum Bronze of low aluminum content. It can also be used for brazing malleable iron and light gauge steel.

Deposited Chemical Composition % (Typical)
Dependent on weld process

(Nominal) All Weld Metal Properties Requirements
Tensile Strength                                          50,000 psi

Preheat / Interpass Recommendations
Preheating copper – base alloys is frequently unnecessary provided section thicknesses are not unusually heavy.
Preheat and Interpass temperatures will vary depending on section thickness, selected weld process and other variables.

ALLOY DESCRIPTION AND APPLICATION,

Nickel-Aluminum Bronze filler metal is used
for MIG and TIG welding of cast and wrought nickel-aluminum bronze parts such as ship
propellers, where high resistance to corrosion, erosion and cavitations in salt or brackish water
is required. Nickel-Aluminum Bronze is a very popular filler metal in offshore technology for
such items as sea-water desalting, shipbuilding and repair. Also used in the power plant and
chemical industry for pumps and tube systems. Helium may be preferred when TIG welding on
Al-bronzes that has 300°F maximum interpass recommendations.
