Re: [MW:31415] Unlisted Material AWS D1.1

Dear ,

We are the one who need to prepare WPS/PQR.

We Tried with 7018 Electrode (Under Matching strength of Base Metal).

Tensile: ~630Mpa.
Bend:~ Cracks on weld area.
HT on Weld~200 HBW

How do we make PQR based on this Data ? Means based on Under matching clause of AWS D1.1 in explanation.

Dear Gents,

I got one WPS for  hardox 450 

(https://www.mtladv.com/wp-content/uploads/2016/01/168_HARDOX_450_UK_Data-Sheet.pdf)

Required Code: AWS D1.1

Plate Thk: 25mm

My concern is that as per given Data sheet there is not specified Tensile Strength ,on what basis we can accept Report of Tensile Test?

This is my first experience with unlisted material.

Thanks & Regards
