RE: [MW:20380] RE: 20357] Re: Welder Qualification

QW-301.2, 2nd paragraph,  “The weldor or welding operator who prepares the WPS qualification test coupons meeting the requirements of QW-200 is also qualified within the limits of performance qualifications listed in QW-304 for welders and in QW-305 for welding operators.  He is qualified only within the limits for positions specified in QW-303.”

 

Obviously, in such case, the weldor/welding operator is not working to a qualified WPS.

Any reference that for the WQT of test plate doesn't require a WPS  ?

Only exception is for a weldor performing the procedure qualification test plate welding.  He would be qualified while welding without a qualified WPS in hand.

Is a WPS is required for conducting WQT  :ANS : YES, WPS is req during the WQT
can we use a preliminary WQT  : ANS : NO
The WPSs shall be identical for all the essential variables, except for the
preheat temperature and PWHT requirements. or has an SWPS
adopted in accordance with Article V,ASME SEC-IX

Gentle men,

 

My question is regarding to the welders qualification test, My client is insisting to use a qualified WPS for qualification of WQT, Is a WPS is required for conducting WQT? or can we use a preliminary WQT or just follow the essential varialbles list as per ASME Sec IX?

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...

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

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, ...
