Re: [MW:19372] Re: SEC-IX RT acceptance

Hai
Noted the responses from all and thanks..but still if project spec. Is silent and sec.ix doesnt have any ruling on other defects (porosity, sla g , under cuts, uf,etc..then a welder on test making 2mm u/c in test but then he passed and send to asme b 31.3 project where 1mm is the maximum u/c...that itself is contradicting...I feel sec.ix criterias must be strong where in most cases we rely on welders (random ndt)...please share ur opinions
Thanks in advance,
Kumar

Dear Kumar,

Nothing mentioned in ASME Section IX regarding undercuts, under-fill etc.

Because ASME is based on manufacturers responsibility it would be the responsibility of the manufacturer to determine it's own requirements for this kind of defects, this can be classified as Good Workmanship.

In my opinion this should be discussed in front before start of production at a manufacturers workshop (for example during a kick-off meeting) in order to avoid any discussions afterwards.

Dear All,

When conducting  WPQT(welder performance qualification test), the
acceptance criteria for both visual & RT is SEC.IX, but the these are
seemed to be much short & liberal. like,

Visual- complete fusion & penetration only required for visual, then
what about undercuts, underfill, re-inforcement height etc ?
RT- only chart given is for porosity comparison (attached herewith).
what about slags and other defects?

If anybody has more details of the above part of  SEC.IX, please share.
due to these reasons some times we find difficulty to judge sub-con
welder performances.
could we refert the construction code of the intended project in that case?
Appreciating your valuable feedbacks.
Thanks in advance,
Kumar
