Hi, you can build up to the required root gap by GTAW with suitable WPS and confirm by PT before start Root welding by SMAW.
Thanks & Regards,

Subject: [MW:12110] Repair procedure on severely punctured root
To: "Materials & Welding" <materials-welding@googlegroups.com>

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?
