Go ahead per 452.6-Table-IX-ASME...Thanks...MuneebFrom: Rejoy ThomasDate: 2019-08-13 22:35Subject: [MW:29950] Regarding Fillet weld WPS (for less than 5mm thk)--Dear all,Can I weld a socket/fillet joint, where the thickness of base metal (pipe to half coupling) is less than 5mm, by using a WPS which is qualified for 5-50mm thickness (GTAW+SMAW, P1 to P1), since there is no groove/base metal thickness involved in fillet welds!! Kindly refer the clause during reply. Your earliest response would be highly appreciated!!Thanks & RegardsRejoy Thomas

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...
