Re: [MW:23818] Welders Qualification Filletwelds.

By Materials & Welding
According to ASME IX:
 
 

QW-303 LIMITS OF QUALIFIED POSITIONS AND DIAMETERS (SEE QW-461)

QW-303.1 Groove Welds — General. Welders and welding operators who pass the required tests for groove welds in the test positions of Table QW-461.9 shall be qua­lified for the positions of groove welds and fillet welds shown in Table QW-461.9. In addition, welders and weld­ing operators who pass the required tests for groove welds shall also be qualified to make fillet welds in all thicknesses and pipe diameters of any size within the lim­its of the welding variables of QW-350 or QW-360, as applicable.

QW-303.2 Fillet Welds — General. Welders and welding operators who pass the required tests for fillet welds in the test positions of Table QW-461.9 shall be qua­lified for the positions of fillet welds shown in Table QW-461.9. Welders and welding operators who pass the tests for fillet welds shall be qualified to make fillet welds only in the thicknesses of material, sizes of fillet welds, and diameters of pipe and tube 27/8 in. (73 mm) O.D. and over, as shown in Table QW-452.5, within the applicable essential variables. Welders and welding opera­tors who make fillet welds on pipe or tube less than 27/8 in. (73 mm) O.D. must pass the pipe fillet weld test per Table QW-452.4 or the required mechanical tests in

QW-304 and QW-305 as applicable.

Goodmorning.

To qualify a welder who's weld a filletweld, you have to take 1 macroetch and 1 fracture test.
The question is : When it is not possible to break the fracture test or when the fracture test doesn't breaks, what is the possibility (according ASME IX) to qualify the welder.?

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, ...
