WELDER QUALIFICATION

[gaurav mongia]

IF A WELDER IS QUALIFIED FOR P1 material and in code it is written
that he is qualified upto P11.

i wanna know what will be reason that a welder can do welding on all
material upto P11 instead he is only qualified in P1

[Muhammed Ibrahim]

 

 

Not only P11. Also P34 & P41 thru P49. The reason is, the skill of the welder required to weld any of these material is same. So he can proove it in any one P No. mentioned .

 

Regards,

Muhammed Ibrahim

This is correct that the welder can weld on all of these materials but do not ignore the other variables. For example the welder will be restricted to the Fnumber filler material he qualified with. An example is a SMAW qualification. When a welder qualifies on P1 material with a matching F4 SMAW filler he will be qualified to the base material range stated below and with F1-F4 carbon steel filler material. This will not qualify him to weld with F5 stainless steel filler material which is needed to weld with matching filler on P8 materials. The same concept will apply to various other P numberd materials. To fully understand this concept and the other variables that will restrict a welders qualifications, read article 3 and QW-416 in ASME Section 9 Regards, Dale Jones --- On Thu, 4/16/09, Muhammed Ibrahim <ibra...@gmail.com> wrote:

As you said to weld with F5 stainless steel filler material which is needed to weld with matching filler on P8 materials.I would like to add more...i.e. as per QW 423 Alternate Base Materials for welder qualification we can weld P1 materiel also with F5 SS Filler  in order to qualify welder for any particular P8 WPS.
This is economical as well as within limit of code.
Please correct me if my interpretation is wrong

Yes you can weld P8 to P8 with E309  and qualify for SS as per F no , In GTAW F no 6  qualifies for Cs and SS also

Dear all,

I would like to add a point here. So far as I understand, you need to use a
qualified procedure for welded qualification as well (Refer QW 301.2). In
this situation, you cannot use any hypothetical WPS (like, P1#P1/F5) unless
otherwise you qualify the same accordingly. I remember we had qualified
such procedure once and for all when I was WE at L&T Hazira Works.

Best regards,

Prasad

Provided you should have PQR qualified for combination mentioned in code and
it should be compatable

purpose of welder qualification is to check welding skill. welding skill is required more or less similar to weld metal groups from p1 to p11.
