[MW:28829] As per B31.3 2012 & Section IX

By Materials & Welding
Dear All,

Welding Process -GTAW+SMAW
PQR Thickens is 25.4mm
And Material is A106 Gr.B My query is as below -

1) For Sour Service what are the test we required and what is the minimum and  maximum thickness qualification for WPS.
 
 a) What is the Base metal thickness Range and  Deposited weld metal range as per B31.3 for GTAW & B31.4 for SMAW.

 b) As Per ARAMCO & Sec IX- AWS No(Class) ER 70S-2 / 3 can we use in WPS . but in PQR they have used only ER70S-6

Please looking your favorable reply on my query with  standards. 

Thanks and Regards
Kiran

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...
