Pump Impeller crack repair

[alexcalan...@gmail.com]

Dear Experts,

 

We have a pump impeller with crack for repair. The material specification for this impeller is Aluminum Bronze Casting (AlBC3 / ASTM C95800).

 

With this regards, what should be the appropriate welding filler or electrode to be used for this type of material?

 

Thanks in advance for your support.

 

Best regards,

Alex

Dear,

U can use ERCuAl-A2 

Take care if the pump working in heavy corrosive fluid , then impeller to be heat treated after welding repair

Best Regards ,
