Re: [MW:21709] Table 4.5 34) ---AWS D1.1

Hi,

Please find below my suggestions as marked in RED.

Question.
1.) Can i write WPS range qualify to backing gouging CJP double V or Single V butt joint.? - PQR with ceramic backing or with back gouging qualifies for with back gouging or backing only. For this question answer is qualify for CJP Double V only. not qualified for single V (without back gouging)
2.) And, if i have PQR qualified with back gouging, Can i write WPS range qualify with ceramic backing or not.? - Yes. with back gouging also qualify for with backing.

Thanks & Regards,

Hi,

It simply means that when you CANNOT take away backgouging/backing from a wps, but you are free to include backgouging/backing in your wps. When a procedure is qualified with backgouging/backing, your wps will always be with backgouging/backing either ceramic, or permanent. But when you have a PQR without backgouging/backing you are free to include this procedure in your wps.

Hope it clarifies.

Dear All

                  Please explain in table 4.5 34) The omission, but not inclusion, of backing or backgouging.

If i have PQR qualification test CJP single V butt joint with ceramic backing.
Question.
                     1.) Can i write WPS range qualify to backing gouging CJP double V or Single V butt joint.?
                     2.) And, if i have PQR qualified with back gouging, Can i write WPS range qualify with ceramic backing or not.?

Best regard.

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...
