Re: [MW:15903] Titanium Dished End Forming

Sir,

I totally agree with you that titanium should be welded with Tig preferbably. But currently we are trying to develope Mig for titanium . Also we have welded groove joint with Mig without any discoloration of the weld with almost nil spatter. Totally silvery shiny appearance.

Wanted some help in getting information regarding Black colour soot formation on sides of weld after MIG welding is completed.

Awaiting your reply sir.

Regards,

Hrushikesh H Sangamnerkar

Hi! Most of the time It is always better to use TIG process rather than MIG for welding of Titanium components Regards   Hegde P.B. +918805593046 --- On Wed, 7/11/12, Hrushikesh Sangamnerkar <hrushi612@gmail.com> wrote: From: Hrushikesh Sangamnerkar <hrushi612@gmail.com> Subject: Re: [MW:15870] Titanium Dished End Forming To: materials-welding@googlegroups.com Date: Wednesday, 7 November, 2012, 8:30 PM Dear Zakar Ali, Wanted some info regarding Mig welding for Titanium...i am currently facing problem of black colour soot formation during welding..if u have sm information regarding the same then pl share.

Precauions:   1) Cut edges should be free from oxides/any other impurity. 2) While forming use SS liner in between the die & base metal. 3) Use more no of strokes while pressing because Ti has high spring back action. 4) If any crack occured, repair it by welding, no issue   Do not go for hot forming.
