Dear Experts,

As per Sec.IX. Table QW-442 (A Numbers) for A-No.1, Mn (Max %) is 1.60 , but one of our Kiswel SAW MTC is having 1.63 (wt. %) Mn in the chemical composition of the weld metal under PWHT Condition (602 Deg.C x 9 Hrs) - It can be considered under A No.1 - Please confirm

Thank You & Regards

In MTC , if Weld metal , Mn > 1.6 % , then A NO can not  be A NO - 1 

Pl; check and do needful accordingly

You can do the following - 

Hope what A no you mentioned above , have been qualified  with PQR brands , both SAW Wire and Flux.

Make A no as   ----

Address Brand names of PQR 'S SAW Wire and SAW flux in PQR and WPS both.

Ensure that CMTR is EN 10204 TYP 3.1 

Thanks
