Re: [MW:29502] Aluminium Bronze welding

You can maintain flow rate of argon gas @ 15 LPM.

Hi....Prem 

Hereafter considering below points as per you, Plz share with us what was flow rate l/min for Argon gas ?

Use 99.995% pure argon

Preheat 150 – 180 ˚C

Inter pass temperature @200 ˚C

Inter run cleaning is very important to remove surface oxides 

Thanks & Regards,
