[MW:30915] Re: Welding of Dissimilar Thickness & Dissimilar P number

By Materials & Welding
Dear Expert need your opinion.

I have WPS/PQR of dissimilar metal GTAW (F11 to SS316L) with Inconel Filler for high temperature application. Inconel filler selected according to API 582 guidelines..but our end user is not accepting Inconel filler because it doesn't have Moly content which is present in base metal.

Any document or write to prove correctness of Inconel filler?

Dear Expert,

Need your guidance,

I have PQR with P1 to P43 with 10 mm thickness,

Can i use this PQR for Joint with 10 mm (P1) & 45 mm (P43) under following clause?

Clause no QW 202.4.



Thank you

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

By Materials & Welding
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...
