Re: [MW:15383] Aluminium Bronze welding

Hi   I feel that you should maintain a preheat and interpass temp of @ 180/200 degrees Celcius. Inter-run cleaning is very very important to remove the surface oxides so that better fusion takes place in the next run. You have to control your welding parameters very accurately during welding.   Regards   Prem Nautiyal --- On Mon, 9/24/12, bo gyi <aungbomyint@gmail.com> wrote: From: bo gyi <aungbomyint@gmail.com> Subject: Re: [MW:15374] Aluminium Bronze welding To: materials-welding@googlegroups.com Cc: prem_nautiyal26@yahoo.com Date: Monday, September 24, 2012, 5:29 AM Hi  Base material is B171 C61400 & 99.9995% argon is used.  Regards, On Friday, September 21, 2012 10:01:11 PM UTC+8, prem nautiyal wrote: Hi   Its not an easy task to weld Al bronze.

Can anyone advice?
