Re: [MW:35083] WPS concern

Dear Nilesh,

No, you cannot use the same WPS for IS 2062 E250 material if it was qualified for IS 2062 E350 material. According to AWS D1.1, WPS qualifications are specific to the tensile strength of the material, and IS 2062 E250 and IS 2062 E350 have different tensile strengths (410 MPa vs. 490 MPa). A new WPS qualification is required for IS 2062 E250.  

Regards,

AB

as IS 2062 E250 - Tensile strength - 410 MPA & 

IS2062 E350 - Tensile strength - 490 MPA

Please suggest your views.. Urgent.
