Re: [MW:34486] ER70S-2 and ER70S-6 (GTAW Process) - A number

it means  need not test weldmetal again while doing PQR.

just to update
ASME Boiler & Pressure Vessel Code 2023 Edition Significant changes include:
-Added an optional supplemental "A" designator to indicate that an ER70S-6A electrode or R70S-6A rod has met the chemical composition requirements of A-No. 1 (SFA-5.18/SFA-5.18M).
-Added optional supplemental designators to indicate ranges of shielding gases for which an electrode meets the requirements for classification, including any optional, supplemental designators. This resolves major issues previously associated with determining the A-No. for these filler metals.

ER70S-6 chemical composition does not allow A-No allocation.

Please refer QW-404.12 (f) for code restriction.

Code doesn't restrict but u will not get it in cut to length. Hardness will also increase due to more Mn, Si. It is better to add ER 70S3

Dear All,

My PQR is qualified with ER70S-2.

Can I use ( Mention) ER70S-6 in WPS.

Regards
Kiran

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...

Re: [MW:10788] ON PLOT PIPING & OFF PLOT PIPING

By Materials & Welding
Piping systems involved for the flow lines and gathering lines from the well head isolation valve to the production facility or processing plant isolation valve are determined as OFF PLOT. ON PLOT defines piping system in the processing plant and production platform. ANSI/ASME B31.4 applies for off plot piping system. B31.4 allows the use of either API 1104 or ASME section IX (as appropriate). However, occasionally, a very small system such as piping within 500 feet of a processing plant (some client also said 400 feet) may be declared B31.3 rather than B31.4. When B31.3 is invoked, only ASME Section IX is used. before you decide which code to use for welding procedure and/or welder qualification for pipe welding, you have to know the design and construction code applicable to the system. Please read far enough into scope and diagram illustrating the application of either B31.3 and B31.4 hope this helps rgds 2011/4/21 pradip kumar sil < pradipsil@gmail.com > Dear all, ...
