Re: [MW:32032] Welder qualification

1. CuNi - 12.7 mm thickness  -  Not permitted 
    Reason - 
    F NO  34 - Welder qualified up to 11.08  mm only .
    Maximum metal qualified  is qualified using F NO 6  filler wire  and NOT with F NO 34 

2. CS - 1" OD -  Not permitted
    Reason - 
     Welder qualified  from   OD 73 mm   and above  with F NO 6 .
      So P NO 1  + 1 "  OD  using F NO 6  filler wire is not permitted 

  F NO of one qualification  and   diameter  of other qualifications can not be  considered for production welding.

Hi gentlemen 

I have doughty in welder qualification. 


The welder having two jcc.

1. GTAW - OD - 1inch, Thickness- 11.08mm, P no. 34, F no 34

2. GTAW+SMAW - OD - 2 7/8 Inch, Thickness - unmimited, P No. 1, F no. 6.


Now my doubt is 

The welder can weld ?

1. CuNi - 12.7 mm thickness 

2. CS - 1" OD

How? If not why?

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

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...
