Hi Kiran, For SAW the wire flux classification is important than filler metal alone. Sec-IX,QW-404.9 addresses this issue. A change from EH14 (1.8% Mn) to EL8( less than 1% Mn) would cause significant reduction in weld metal mechanical properties. Hence this change may not be allowed unless a new PQR is qualified. Thanks. Welding & Metallurgical Specialist Ontario , Canada . Email-pgoswami@sympatico.ca, pgoswami@quickclic.net
Dear Sir Can we weld with Filler wire EL8 with supporting PQR EH 14 Filler wire (having same F no:6) Material IS 2062 Construction code -BPVC Section IX Process-SAW Process. Thanking you CH.V.V.N.KIRANKUMAR +91 7898905072 --
