A new qualification was made with BS3100 Gr A2 to SS304 pipe welding in 6G position. Hardness value of Weld while testing was found to be 415 and 418 HV10, while in other areas of HAZ, Body where within the range of 175-198 HV10.
Kindly give your suggestion on why this drastic change in hardness and the acceptance of it.
