Hi, When combination WPS,Base metal range will not be limited for each process.But weld metal thickness is limited Thanks & Regards, (Karthik) Karthikeyan.S QA/QC Manager Getabec Energy Co.,Ltd. 379,Moo6,Soi8,Nikhomphatana, Rayong-21180, Thailand.

FCAW –  Fill and Cap. Base Metal thickness: 25.4mm / 10" Pipe Dia Code : AWS D1.1,2010. SAES-W-013.   Since SAES-W-013 Clause 5.4.2 is confirming that FCAW process shall not be used for Root and we have followed the same condition during the PQR qualification.     Our interpretations are as follows:   1.       As per the AWS D1.1, Table 4.2 - If we use the plate thickness of 25mm over, qualification range will be 10mm to unlimited. 2.       I have stated in the WPS that SMAW process is only for root and hot pass and FCAW for FILL &CAP. 3.       Based on the SAES-W-013 and AWS Table 4.2, the QUALFICATION range for the WPS is 10mm to unlimited or 0.5 to 1.5 of base metal thickness. 4.       For the combination of Welding Process ( SMAW+FCAW), The thickness limitations will not be applicable for each process since root and Hot Pass of SMAW is not for FILL & CAP 5.       SMAW WELD METAL is backing for FCAW. 6.       We always use the WPS as SMAW –ROOT /HOT Pass & FCAW – FILL&CAP.   Clarification required:   1.       For the combination of welding process, the thickness limitation will not be for each process. 2.       Base metal Qualification range will be considered for both the process. ( as below).       With Kind regards,   S.Elumalai. ****************************************************************************************** CONFIDENTIALITY NOTICE This e-mail and any attachment are confidential and may be privileged or otherwise protected from disclosure.
