Re: [MW:33043] Fwd: WPS TO QUALIFY THE OF THE WELDER

By Materials & Welding
Sometimes it is unavoidable that some Nozzle welds overlap Circum seam or Longitudinal seam, in that case the circum seam or Longitudinal weld seam shall be flush grinded and RT performed before welding and after successful RT results the Nozzle weld may be welded over flush grinded seam and perform necessary NDT after welding.

I believe your question is Nozzle weld overlapping longitudinal seam.

Thanks & Regards

Dear experts , 

I need valuable guidance on following,

Overlapping of circumferential weld joint over longitudinal weld joint in pressure nozzle is acceptable ?  If yes , then as per which reference standard and clause

Thanks

Thanks Karthik but I'm sorry because the wording of my question was wrong.

Our WPS-XXX was qualified in 2012 = SMAW / Manual / P·No.: 1 Group No 1 y 2 a P-No: 34 Group No. N/A with 0.237" thickness in position 6G (SA-106 Gr. B to SB-466 ALLOY 706) with backing ring (SA-36) / Filler metal E-NiCu-7 of 3/32" and 1/8" / minimum preheat temperature 400° F and interpass temperature 600° F.

Nowadays in the year 2022 we need to qualify a welder in fillet welding according to the Figure QW-462.4(c) pipe to pipe of ASME IX using the WPS-XXX described above.

Question: Can we use the WPS-XXX to qualify the welder in fillet welding according to the Figure QW-462.4(c) pipe to pipe of ASME IX?

Thank very much

Can I use a WPS qualified with the SMAW process in position 6G on pipes Copper Nickel to Carbon Steel with a thickness of 0.237" and with backing ring to qualify the skill of the welder in fillet welding with the SMAW process in position 5F on pipes Copper Nickel ( O.D. 2 ½" thickness 0.280") to Carbon Steel (O.D. 3" schedule 160 in accordance ASME IX?

 

Thanks

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, ...
