Does we need UT for fillet welds ? could you tell me more as per client
spec or Code req. ?

Subject: [MW:9054] UT of Fillet weld

Dear All,
During UT inspection of fillet weld, Does we need both angle probe and
normal or TR probe?

Thanks & Regards,
Mohd. Sadique Sheikh

You can not UT a fillet weld. RT could serve you but, you would need an experienced film reader who could recognize the difference between a crack and the root it self. You could use the DC mode with MT unit that is effective to about 1/4 inch in depth. Forget PT that is only applicable for surface defects. My question would be is there a reason why you think there might be cracking. Did you have failure of the welds? If you established you weld procedure in accordance with AWS D1.1 there in not a need to investigate the root of a fillet weld unless, there are indication of cracking in the weld. If that is the case you have to establish why is it cracking. To investigate roots of fillets on fear is not pratical nor reasonable or required unless established by supplication specification.

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...
