[MW:4957] Comparision between ISO15614 Part 1 and AWS D1.1 PQR requirements

By Materials & Welding
You can't write a WPS based on the ISO 15614 PQR. however you may use both WPS/PQR from other standards, provided the designer takes the responsibility based on the specific structure or service conditions or both (refer para 4.1.1.2 of AWS D1.1). alternatively you can use SWPS provided in AWS D1.1 as prequalified procedures.

Hi Raghu,

 

Could you please advise on “comparison between ISO15614 Part 1 and AWS D1.1 PQR requirements”.

Also can a WPS be as per AWS D1.1 and PQR be as per ISO15614 Part 1?

 

Am not able to post this on blog.

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...
