Re: [MW:16381] Filler wire for Aluminium to CS TIG welding

Hi   Such type of joint i.e Aluminium # CS is not possible by TIG welding in Heat exchanger.    In automobile industry, Aluminium # CS joints are being done by Friction welding and Friction Stir Welding. However in such type of joints there are formation of intermetallic phases like FeAl3 which can make the joint brittle and reduce ductility.   Hence such type of joint is not suitable in pressure vessels.   You have to look for alternate design change.   Regards   Prem Nautiyal --- On Mon, 12/24/12, Ashok Shende <shendeashok08@rediffmail.com> wrote: From: Ashok Shende <shendeashok08@rediffmail.com> Subject: [MW:16315] Filler wire for Aluminium to CS TIG welding To: materials-welding@googlegroups.com Date: Monday, December 24, 2012, 9:32 AM Dear experts we are having a project of aluminium heat exchangers with tube side MOC as aluminium SB 209. Here I want to make confirm the suitable filler wires for TIG welding of Aluminium to SA 516 GR 60/70. Thanks in advance.
