Re: [MW:10170] T & t conflicts?WPS is 1.5 to 14.22mm, can i qualify welder in T - 12.70 for 5 to 25.4mm ? is possible r not?

Dear all,

I have to qualify the welder as per section IX. The material is P1 and group1. I have qualified WPS with me. The thickness of the pipe is 7.11 and 6inch dia & position 6G.

Root/hot pass is TIG welding process with ER 70S-2 and filling capping SMAW with E7018.

The welder says he cant complete it before lunch. He goes for lunch and comes after

2hrs. As far I know the welder qualification should be continuous eventhough weler has completed root and hot pass. Shall I allow him to go? or what is the time lapse as per secIX?

Could you please some one can explain me how to use QW-353 ( SMAW-variables) &

QW-356(TIG-Variables).

Is it mandatory to check the heat input of WQT of all the passes? If yes, what will be the maximum heat input allowed? is it as per WPS or what?

Finally what are the main documents to be checked while qualifying welder qualification test?

thank for your answers.

regards

Ilan

Hi,
Case : 1 - You can use this WPS to for welder qualification up to the test specimen thickness of 14.22mm.But in production welding if you want to weld more than 14.22mm,you cannot use this wps.You have to use another WPS with the thickness qualified of 14.22 and more.

Case 2: Yes.But if you want to use this welder to weld less than 5mm,you have to use another WPS qualified for less than 5mm.

Thanks & Regards,

Dear all

As per ASME sec 9..
WPS in base metal T qualified is 1.5 to 14.22mm,
can i qualify a welder(WPQ) in T - 12.70 for 5 to 25.4mm ? is
possible r not?

& vice versa.
WPS is 5 to 25.4mm, can i qualify welder in 7.11 for 1.5 to 14.22mm.
is possible or not?

pl comment on above ?

Regards
Srinivas

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...
