Hi,
The welder can be accept for 3F and 4F shall be retested.Code doesn't restrict to reject both.But in some Project specifications/Customer rejects both if you do qualification 2 or more positions quaified at the same time.

Thanks & Regards,

Dear experts,
 
              Good day for all. While qualifying performance qualification for the welder with
3F and 4F fillet welds, I had noticed lot of undercuts and poor weld profile so I have rejected 4F piece. But 3F weld somewhat ok and its accepted.
 
I have to qualify this welder as per section IX. As far as performance qualification is concerned if the one piece is failed the entire qualification test is failed.But our contractor insist me to accept 3F. Should I reject both pieces or reject only one which is failed.
 
Kindly someone correct me if i am wrong and if possibel refer the para in section IX or from
QW-300 of section IX.
 
Thanks and regards
Raja K

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...
