4047 Aluminum TIG Welding Rod

Current Position :HOME/Welding Wire/4047 Aluminum TIG Welding Rod

ER4047 aluminum TIG welding  rod
 
ER4047 is a eutectic Al Si alloy with 12% silicon, low melting point, good fluidity, and has good corrosion
resistance. But it is anodized after the color is black.



 
Application:
suitable for Al Si, Al Si mg, Al Si Cu mg wrought aluminum and aluminum (>7%Si) argon arc
welding. More widely used for pure aluminum, aluminum manganese, aluminum silicon magnesium alloy.

Performance & Usage
 
This type containing 12% silicon,which can be adapted in welding all kinds of 
forging and casting or extruded shape aluminium alloys.And it has advantages
 of low melting point and good fluidity which avoids the distortion after welding.
Usage:jointing or overlay light alloy processing.
Shielding gas Argon, Helium, or Argon/Helium—mixtures.

Note :
 
1. Al Si Rod although there are strong crack resistance, but plastic is poor, so after welding need plastic
deformation joints, should avoid using aluminum silicon Rod.
 
2. The oxide and oil stain on the edge of the workpiece must be removed before welding.
 
3. Welding can be used when the plate holding molten metal, to ensure weld forming.
