Re: [MW:15433] Aluminium Bronze welding

Also preheat is must.   Regards   Prem Nautiyal --- On Sun, 9/30/12, kannayeram gnanapandithan <kgpandithan@gmail.com> wrote: From: kannayeram gnanapandithan <kgpandithan@gmail.com> Subject: Re: [MW:15374] Aluminium Bronze welding To: materials-welding@googlegroups.com Cc: prem_nautiyal26@yahoo.com Date: Sunday, September 30, 2012, 1:13 PM use helium+argon mixture need not preheat clean properly pandithan In-charge/wt Cethar On 9/24/12, bo gyi <aungbomyint@gmail.com> wrote: > 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. >> What is your base material grade ? >> Clean base metal and filler wire before welding. >> Use 99.995% pure argon. >> •Preheat 150 – 180 ˚C >> •Inter pass temperature @200 ˚C. >> •Inter run cleaning is very important to remove surface oxides >> >> Regards >> >> Prem Nautiyal >> Cell: 9769316004 >> >> --- On *Fri, 9/21/12, bo gyi <aungb...@gmail.com <javascript:>>* wrote: >> >> >> From: bo gyi <aungb...@gmail.com <javascript:>> >> Subject: [MW:15353] Aluminium Bronze welding >> To: material...@googlegroups.com <javascript:> >> Date: Friday, September 21, 2012, 7:46 AM >> >> Hi Sirs, >> >> Currently, I am doing procedure for Aluminium Bronze (61400) using GTAW ( >> >> ERCuAl-A2) process by Argon shielding gas but found that fusion of filler >> >> metal & base metal is not nice. >> >> Can anyone advice? >> >> Thanks and regards, >> >> Bo >> -- >> To post to this group, send email to >> material...@googlegroups.com<javascript:> >> To unsubscribe from this group, send email to >> materials-weld...@googlegroups.com <javascript:> >> For more options, visit this group's bolg at >> http://materials-welding.blogspot.com/ >> >> http://www.linkedin.com/groups/MaterialsWelding-122787?home=&gid=122787&trk=anet_ug_hm >> >> The views expressed/exchnaged in this group are members personel views and >> >> meant for educational purposes only, Users must take their own decisions >> w.r.t. applicable code/standard/contract documents. >> >> >> >> > > -- > To post to this group, send email to materials-welding@googlegroups.com > To unsubscribe from this group, send email to > materials-welding+unsubscribe@googlegroups.com > For more options, visit this group's bolg at > http://materials-welding.blogspot.com/ > http://www.linkedin.com/groups/MaterialsWelding-122787?home=&gid=122787&trk=anet_ug_hm > > The views expressed/exchnaged in this group are members personel views and > meant for educational purposes only, Users must take their own decisions > w.r.t. applicable code/standard/contract documents. > > >
