Any welder welding on pressure part must be a qualified welder incl tacks. There is no concession given in code for tack welders. All are qualufied welders. Some may be less experienced. Those u can use for tacks. But qualified Yes. Unqualufied welders shd not even touch pr parts.Rgds Prakash Gotimukul AIS----Greetings,It is not the tack welder qualification for tack, or not even a fillet qualification for a tack in groove, but it is the qualification of welder and welding operators in groove welds who qualifies the tack as per trailing mail it is very clear that ASME B 31.3 interpretations are stirngent saying fillet qualified groove tacks also? its says no...So in your case same applies you dont need a tack qualified welder to tack a weld, but a qualified grooved welder.If i am in your place, i will choose the poor performance welder though are qualified, but still not consistent to get a qualified weld or a repair welder or a welder who is in revoking stages, if you quantify you will get a sum to accompay in your tack bay, this everything comes under planning and not leaving loop holes for TPIs, if you are following as per written documents.orIf your client or TPIs are bold or wise thinkers to know the consequences of flushed off tacks then it is not a big deal but take a verbal approval for non qualified welder, but you make sure they are good enough to make tacks.Hope its clear.SAES-W-0118 Welder and Welding Operator Qualification
8.1 All welders, welding operators, brazers, and brazing operators shall be qualified in accordance with the ASME SEC IX and SAEP-321, SAEP-322, SAEP-323, and SAEP-324,as applicable, for all welding, including tack, temporary, and repair welds.Regards,Mohamed Muneeb Mahaboob.
Ok noted but my tack welders are working at fitup section and welders are working at Welding area.my concern is that how I am sure that my tack welder is qualified tack welder.is there any test is required?--On Mon, 8 Oct 2018 at 7:41 AM, Mohamed Muneeb <muneebslsa@gmail.com> wrote:Also if SA company project then required.--On Sun, Oct 7, 2018, 5:02 PM Kannayeram Gnanapandithan <kgpandithan@gmail.com> wrote:What is the code of contruction.

I am working in fabrication company of piping.My company divided the the welders in two different area-(1) tack welders & (2) welders.Tack welders are working at fitup section & welders are working in welding area.Now my question is that-is it required to qualify the tack welders?If yes then why? If yes than how i will proceed & how to make the prolongation of tack welders?

Thanks for your guidance.
Still I am not clear with the concept
ASME Sec IX says all welding shall be done by a qualified welder, So
for tacking groove joint,
welder need to be qualified for groove joint.....?
Or if he qualified for fillet joint, he can allowed for tacking groove
joint (Tack either incorporated into the final weld or removed).....?
please reply
