Dear C.R.Gandhi,

For
1) 2.95 mm. for TIG and 6.6 mm. for SMAW. and All Size for Fillets.

2) i am not sure but as per my understand QW-202.4 is for Dissimilar Base metal Thickness But, you have PQR for 6 mm(there is no dissimilar thickness).

Dear Experts,   Good day to all. I have 2 cases which are to be shared with you for my knowledge.   (1) I have qualified a WPS of 8.5 mm. Base metal Thk. of P-1 G-1 to G-2. Root Run TIG and subsequent SMAW. TIG weld deposit thk. 2.5 mm. and SMAW weld deposit thk. 6 mm. PWHT- Normalizing and Tempering with Impact test at MDMT (-45º C.)   As per my opinion, as per QW-403.6- Minm. T qualified shall be 1.5 mm. & Max. will be 9.35 mm. as per QW-407.4. As per QW 451.1 qualified deposited weld metal thk. range will be 2t (viz. 5 mm. for TIG and 12 mm. for SMAW.) for groove welding. and for Fillet- deposited weld metal thk. range will be all fillet size. Am I correct?   (2) I shall have to qualify a WPS of 6 mm. Base metal Thk. (T) of P No. 8 Group 1 to itself. Complete TIG.    As per my opinion, QW-202.4 (b) (1) and QW-451.1 Min Qualified T shall be 1.5 mm. and no limitation on Max. T qualified. As per QW 451.1 qualified deposited weld metal thk. range will be max. unlimited for groove welding. and for Fillet- deposited weld metal thk. range will be all fillet size.
