RE: [MW:20713] ASME SEC IX QW202.1

Attached is a copy of 2013 ScIX QW-202.1. The following is my interpretation of the requirements.

Three conditions are set up in the case of a specimen failure:

1) (2^nd paragraph) Failure was caused by something unrelated to the welding conditions. This could be a failure of the grips, a nick in the specimen, an error in machining, power failure during the test, etc. In this case one for one replacement of the specimen from the original PQR coupon or a new test coupon welded with the same parameters/conditions may be made and the additional specimen tested.

2) (4^th paragraph) If the failure was caused by a problem that requires a change in essential or supplementary essential variables to correct the problem, then a new PQR test plate must be welded and all tests repeated. Personally, I don’t see how the original PQR test(s) would be valid if the essential (or supplementary essential) variables have changed.

3) (5^th paragraph) If the failure was caused by a problem related to welding but that requires a change not affecting the original essential or supplementary essential variables, then a new coupon can be welded and the failed test repeated. The changes made to the non-essential variables or other parameters to obtain the acceptable test(s) must be addressed on the WPS. In this case it is one for one replacement.

Typically a failure of a PQR test will be the result of condition 2) above. In my experience, use of condition 3) is rare.

Just my opinion along with a strong belief that a short cut isn’t necessarily the quickest route to anywhere. Good luck.

Dear Dilinates,
There is no problem if something added or deleted to the main topic in the next para. in any standard or technical documents and with some new conditions. Those are exactly exceptions.

I disagree
Please read carefully: It is written in the 1st paragraph of QW 202.1 "If any test specimen required by QW-451 fails to meet the applicable acceptance criteria, the test coupon shall be considered as failed"

Thanks for the info,

Please note that QW202.1 also allows for retesting ( after considering all ifs & buts in the code/ QW153) from the same test coupon. Now my question is, if one tensile specimen fails, how many additional test specimens shall be tested.

Dear friend,

If any specimen fails to meet the requirements, the test coupon consider to be failed and a new test coupon shall prepare. (It could be with the same parameters or changed parameters)

Friends,

Good Morning,

With reference to ASME Sec IX:

1. If one tensile specimen failed the requirement of QW153
2. How many additional specimens are to be tested QW202.1

Tulasi Ram

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change. Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...
