[MW:3448] Re: Qualification of cladded base metal

By Materials & Welding
Hi tong,
 
You have to qualify the procedure as the same configuration of production. For cladded and buttered configuration you have to make the same test coupon and weld. You have to confiy the chemistry also at the root.

Dear All,
 
I have one query regarding welding qualification of cladded base metal. Our first base metal is Stainless steel 316L to weld with second base metal P5A cladded with Stainless steel 316L. A layer of ENiCrMo-3 was buttered on bevel of second base metal by other. As i know a layer of ENiCrMo-3 act as barrier layer. The problem is how to qualify the welding procedure on stainless steel 316L to P5A cladded with Stainless steel 316L. Is it i need to qualify  P5A cladded with Stainless steel 316L or Stainless steel 316L to inconel ENiCrMo-3 or Stainless steel 316L to Stainless steel 316L procedure. I really need your advice and expertise. What is the best practice or code requirement on qualification of cladded base metal. Advance thank for your kind cooperation and really appreciated
Regards
Tong2je

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...
