Understood, and thanks for the clarification. For a nozzle joint welding in a boiler, third party
agencies allow SMAW process in general.

We have made SMAW+SAW WPS but now using that previous PQR we will qualify SMAW process for nozzle in Boilers we don't have approved WPS for GMAW/FCAW so that's why we need to make for SMAW.Best RegardsPankaj--On Tue, 12 Aug 2025 at 9:54 PM, sridhar cn <sridharcn305@gmail.com> wrote:One out of way query:Why use SMAW process for a 111 mm thick weld deposit? SAW is OK for balance 109 mm thickness.SMAW is inefficient compared to GMAW/FCAW processes. They have an efficiency of 85 to 90%compared to 30-40% in SMAW (due to use of E 7018) and will reduce your welding time and cost factor.Think for a better change!C Sridhar.On Tue, 12 Aug 2025 at 17:24, pankaj pachahara <pankajpachahara@gmail.com> wrote:Dear Welding Experts,
We have recently completed PQR qualification on a 220 mm thick joint using a combination of SMAW + SAW processes.
Material-SA 5160 GR.70
SMAW deposited thickness: 111 mm(E7018-1)
SAW deposited thickness: 109 mm(EH10K)
I now need to prepare a WPS for the SMAW process only. Could you please clarify up to what thickness this WPS will be qualified for based on the deposited SMAW thickness?
Best Regards
Pankaj
