Recently I came across an issue of High Ferrite no. in the weld metal.
Parent Metal : A 304L
Weld Metal : 308L
Welding Process : GTAW
The affected area is only a quarter portion (3'o clock to 6'o clock position) of the 30" pipe where ferrite no has been observed as over 21 FN. and PMI has shown 1.57% of Mo.
Please give your valuable comments and rectification measures for this. Refer the attached photos for clarity.
Thanks and Regards
Harikrishnan
