Re: [MW:32422] Solid Tube Built up WPS/PQR

By Materials & Welding
Dear Sir,

Thanks for your comment but my  question was for Test Coupon Size selection only not with Material, my client is not able to find 40mm plates to make Butt weld and make qualification for PQR and mechanical testing.

They want  us to Testing with Solid shaft on actual job but i m not sure this is way to do PQR specifically for ASME for Base Metal Buildup.

Thanks & Regards
Jaimin Patel

Mr.Jaimin Patel,
fyi,
build‐up of base metal (restoration of base metal thickness):
This is the application of a weld material to a base
metal so as to restore the design thickness and/or structural
integrity. This build‐up may be with a chemistry different
from the base metal chemistry which has been
qualified via a standard butt-welded test coupon. Also,
may be called base metal repair or buildup.

Dear Gents,

we have situation where client have some component like shaft/Tube Solid  of nickel Grade Material and on the surface they have some material loss.

They want to make grinding>welding>maching to restore the original configuration.

  1. Applicable Code ASME SEC. IX.
  2. Required welding max 5mm.
  3. Shaft Dia varies From 1" to 6"
  • Now as i see we can make WPS/PQR based on QW202.3.
  • But I m confused on selection of Base metal thickness and Grove what we need to suggest.
  • Client don't have metal sheets to make on PQR on that they have only Solid Tubes.

kindly give your value inputs on this regard's.
Thanks & Regards

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, ...
