Consumable Impact test requirement
Consumable Impact test requirement
(OP)
Dear Sir,
1) Is it required carry impact test (prior to production )for the consumables while we are using WPS with impact tested ? If it is yes, what temperature we need to conduct and who is responsible to carry out?

RE: Consumable Impact test requirement
ASME codes has a provision of production weld coupons, which is far stringent in European Codes. Failures of any production coupons could hold up all the remaining production welds and production schedule. Should such requirements in design contract,then it's strongly advisable to procure impact tested welding consumables.
Also if the impact test temperature is too low, say -50 Deg or -75/-100 Deg for C.S and few grades of low alloy steels(say 2.5% or 3.5% Nickel Steel), then its advisable to have consumables impact tested in the highest heat input condition, 3G upwards as additional safety.
Thanks.

We are not used any impact tested consumables while qualifying PQR (SMAW/GTAW/SAW/GMAW),however coupon is qualified with impact test for the temp -25 deg C and prepared WPS(for impact test) and this WPS is used for the temperature -15 deg C(MDMT) while production so is it consumables used in production required to be impact tested( ie manufacture certificate with impact test for -15 deg C).
RE: Consumable Impact test requirement
What're the types of materials you're dealing with C.S,LAS?? What're the AWS specifications of applicable welding consumables?? Could you be specific?
Appreciate your response.
Thanks.

RE: Consumable Impact test requirement
Yes, you need to qualify the Welding consumables as per ASME sec-II part C.

RE: Consumable Impact test requirement
therefore, when you select the consumable, you must select the consumable with the impact test which had been done by the consumable manufacture.
BUT related to the impact test preformed by the fabricator depending on the fabricator's quality control system,the ASME CODE don't provision this issue. IF the quality control system describes the material which used in fabrication of production must re-test by the fabricator itself. then impact test and other tests must be done prior to production.
