RE: [MW:26872] Welder qualification

By Materials & Welding

Hi,

 

As per QW 403.18 / QW 423. 1 – if you take qualification on P no 1 to P no 1, then the welder will be qualified for p no 1 to P. no 15F, 34, and 41 to 49

You can take the qualification on P no 1- no problem, it is acceptable.

 

However for P no 1 base material,  your consumable should be F43 for welder qualification, and if any F No changes then you have to see the QW 430 for the same for the permissible…

 

Hope it is clear to you.

 

Thanks & Regards,

Dear Gentlemen,

 

I have to qualify welder with base material in my hand is P-1 to P-1, but but actual WPS done on P-1 to P-43 base material. May i proceed to qualify the welder based on this WPS?

 

Thanks in advance.

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...
