[MW:31295] Query - Regarding the Changes from Previous edition for Welding Procedure Qualifications in AWS D1.1

By Materials & Welding

Dear Experts,

 

Iam sandeep.Raghavan. Iam Writing this E-Mail in relation with the Confusion that I am Facing regarding the Changes in AWS D1.1: 2020 compared to 2015 Edition.

In AWS D1.1:2015, Table 4.5, Point No.27(General), It is mentioned as , A Change in position not qualified by Table 4.1 or 9.9 which are  range of qualifications for Welding position for Welding Procedure in Plates & Tubular Sections Respectively.

But as it Comes in AWS D1.1:2020, The table is replaced by Table 6.5 which mentions , A Change in position not qualified by Table 6.1 or 6.10. Again 6.1 is equivalent to 4.1. But 6.10 is for Welder & Welding operator Qualification Requirements. As per this clause, I feel  Contradictions.(For Eg: 3G  qualifies only Vertical as per 6.1 & Flat, Horizontal & Vertical as per Table 6.10). I believe this must be a Typo Error.

Also In AWS D1.1:2015, for CVN Requirements, 3G Vertical qualifies all position(Table 4.6, Point 6). But the same clause is missing in AWS D1.1:2020. 


Please clarify  my above  queries. 



Thanks in Advance,

Sandeep.P.Raghavan

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...
