Dear Mr. Shaikh,

If the PQR is qualified with E7018, you can use E7018-1 but need to prepare a new WPS with E7018-1 provided meeting the requirements of all other essential & supplementary essential variables.

Refer attached file of asme code interpretation.

Dear All

I have query about use of Electrode with change og classification 

We have WPS for SMAW welding process for P1 material with the E 7018 electrode in that case can we use in production E7018-1 electrode 

Please help me out in interpretation

QW 404.12 (e) from a classification that requires toughness testing
to the same classification which has a suffix which indicates
that toughness testing was performed at a lower
temperature or exhibited greater toughness at the required
temperature or both, as compared to the classification
which was used during procedure qualification (i.e., a
change from E7018 to E7018‐1)

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...
