Re: [MW:12121] Repair procedure on severely punctured root

It's better to apply PWHT after completion of the weld.

Yes you can do weld buildup on the punctured rootface by ER70S-2 (TIG) till you get a uniform root gap of @3mm.
Then weld the root run with ER70S-2 and complete the joint with E7018 provided you have a WPS / PQR for the same.

Dear All,

Material : ASTM A106 Gr. B

Thickness : 12.70 mm

Welding Process : SMAW

Electrodes used as per approved WPS : SFA 5.1, E6010 (Root)+ SFA 5.1, E7018(Fill&Cap)

During through thickness repair, by mistake root pass has been punctured badly(5-8cm in length after complete removal).Unfortunately,now the root gap is almost 10-12 mm wide and it is difficult to weld root again with E6010.In this case what is the better option other than cut and bevel the joint.Is there any problem to build root with GTAW by using ER 70S2 and fill remaining thickness with 7018?




Regards,

Limesh
