Regarding WPS

[Sanjay Kharwar]

Dear All,

Can anyone suggest me, I have a WPS in Sec.IX for Material IS 2062 E250  BR  , so can i use this WPS for IS 2062 E 450 BR also.

No never n cant. Really u know mean of wps. wps is a written guidline to welder to how to do welding with ranger of variables. Suppose u take material A so u select all the parameters according to chemical , mechanical prop of material A.
But now u want to do welding of material B ie mechanical prop chemical prop are diff u have to guide ur welder on diff ranges diff parameter of variable so parameter n ranges are diff for both material A and B ie u have to make separate wps for both material.
Generally if prop are similar but name of material is diff than also u have to make diff wps.
But u are using diff process ie smaw welding for root saw for 1st layer gtaw for 2nd layer and so on for that u have to memtion that all on same wps for each material A and B

And one more thing E250 with quality u r using A B0 BR C and which one for E 450.. sr make ur basics clear on mild steel material because if u work on asme material than its very complicated. and

Yes, you can use the same wps for E 450

[Er Sourav Bohray]

No way !! If thickness is diff , if welding process is diff,, if consumable is diff..

nd chemical composition is diff n tensile strength is also diff ...

Guys

 You cannot use E250 wps for E450, As per AWS D1.1, E250 is falling under group 1and E450 is under group 4, matching filler to the basement were also different.  Refer tables given in Aws D1.1.

A...)P1 to p1 single wps

P2 to p2 single wps 

P1 to p2 single wps

N its common sense diff material diff wps. Open challange to you show me a single wps on which material used is of two diff kind.

But one condition if u are making one weld coupon using two diff grade material than u have to use single wps by mention pno this to p no this.

Eg - pno 1 grp 1 to p no 4 grp 2
