[MW:19984] Re: Calculation of weld metal deposit

By Materials & Welding
Dear Vinit

You need to first calculate the total area of the weld deposit as per joint configuration.
e.g. from your sketch,its seems to a partial penetration weld, however it does not include complete weld details, such as weld size as a additional run.

considering the weld configuration shown in your sketch first figure, it will be a triangle, the area can be calculated using the formula 1/2*a*b*density of material, and accordingly convert the units.

For 2nd figure use a combination of Triangle and arc. Try to divide the area into different forms upto max extent.
After the complete calculation, you need to add the filler material wastage factor (Stub lose in SMAW, spatters excess penetration etc.) which vary according to different processes.
Hope it will help you.

Dear Experts,

We are working on a Alloys Steel header ,size-18" x Sch-160 , with 16 nos of weldolet(size -18 " x 4 ") is to be welded on 18" pipe (SA 335 P22) , i have to calculate the weld metal deposit while welding the weldolet . Please suggest the correct method to calculate the amount of weld metal deposit.( i have attached the welding detail of weldolet)

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, ...
