[MW:18211] RE: 18208] AWS D1.1 Welder Qualification Base Metal range

Dear Ehran,

If base material is covered in AWS D1.1 this is not an essential variable for Welder Qualification.

This means a test weld executed on a material covered by any of the materials groups covers all other material groups (I, II and III).

In case of unassigned material companies engineer can check mechanical properties and if material can be considered to be similar to a listed material (for example S355 material is almost similar to EH 36 which is covered) he may classify the material in to the same group as the listed material in that case it will cover also all materials listed. If material is not similar to one of the listed materials the qualification will only covers the unassigned material in case.

Met vriendelijke groeten / Best Regards,

Dear All,

I couldn't find any base metal range for welder qualification.

Do you think same and what is the reason for this?

If so what shall we write to Base Metal - Qualification Range row on the certificate?

Thanks in advance

Regards,

Erhan Turgut

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...
