RE: Re: [MW:9691] Re: WPS is 4G.. Can i qualify welder in 3G?

Once again, the enquirer has not provided sufficient information to properly reply.

 

There is one exception in the ASME IX that will not allow use of the WPS.  If impact testing is required, then supplementary essential variable, QW-405.2 would apply and the WPS would not be qualified for the vertical position by a PQR welded in the 4G (overhead) position.

 

Note that QW-301.2 states in part that,  “. . . The performance qualification test shall be welded in accordance with qualified Welding Procedure Specifications . . . except . . . preheat or postweld heat treatment . . . may be omitted.  . . .”     Thus if the WPS states that welding shall be performed in the overhead (4G) position only, then the WPS will have to be amended to at least include welding in the vertical (3G) position.

 

Also, a minor comment.  The G, F,and S designations {QW-461.3 through QW-461.8} are qualification test position designators.  The production welding positions qualified to be stated on the WPS are:  flat, horizontal, vertical, overhead, all, or special per QW-461.9.  These qualified positions are limited per QW-461.1 or QW-461.2.   Those with intimate Section IX knowledge are aware of this distinction and only put the G, F, or S designator on the PQR, and not on the WPS.  Their WPS will state Flat (F), Horizontal (H), Vertical (V), overhead (O), all or special (S).

Hi,
QW-461.9 is for PERFORMANCE QUALIFICATION — POSITION AND DIAMETER LIMITATIONS. i.e,If a welder Qualifies with the position specified in the Qualification test column,will be qualified for the columns specified in the right side.

Now the question raised by Mr.Srinivas is As per ASME Sec.IX,If a WPS qualified with 4G position can be used for 3G welder Qualification or not? For this answer is yes.he can use that WPS for 3G or any position welder qualifications.(with all other essential variables are met)

QW461.9 doesn't restrict for WPS qualification.Change in Position is not an Essential Variable for WPS as Per QW252 to 265.

Thanks & Regards,

NO.

Please refer Table 461.9 of ASME sec ix .

When
ever you want an answer you have to say complete details then only

you will get the correct answer.



You have to mention what is the code your supporting PQR u can not

change the code of your PQR qualified. according to that u have to

confirm. Ok even as per section IX also you can not qualify the welder.

Re: [MW:34105] SA266 GR4N 4 Cycle SPWHT

Hi,  You are correct, Minimum refers to the one cycle for which this part will expose until final work shop PWHT. hence mill test certificate shall include this.  Max. SPWHT, refers to additional cycles of heat treatment that are reserved for future repairs during equipment lifetime.  Again, these simulated no. Of cycles shall be specified in MTC.  The idea is we need to make sure that steel mechanical properties are not compromised upon exposure to multiple repairs (i e 4 cycles in your case).  One could say, if steel is subjected to 4 cycles and is ok, then it should by defacto be good for one cycle, yet, this is wrong assumption cause mechanical problems and microstructure of materials varies accordingly based on no. Of cycles for which material will expose. This is apparent in alloy steel and especially for impact test values as an example.  In your case, this forged CS with properties before PWHT can be understood to be " as forged" condition (i.e. Wit...

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...
