Re: [MW:23085] CRACK IN ANGLES , An interesting topic and more interesting issue!

By Materials & Welding
Dear Mr. shokri

Thank you for your reply . I prepared the repair procedure according to En 10163 but because of high volume of surface cracks ( in all over the angle surface )  its not possible to use it.

Is it possible to welding a reinforcing bare in such a surface condition without removing of cracks  ?
According to aws d1.1 Engineer can permit it ?

Please see EN 10025-2, 7.5.3. It will refer you to the EN 10163-1 to 3 for permissible surface discontinuity and repair modes.

Dear expert,

I'm recently working in a structural project as welding qc . During fabrication inspection, surface crack was found in angles material used in project ( as bracing ) so i reviewed the mechanical examination reports ( the tests are done according to En iso 10025-2 ) but absolutely mechanical properties and chemical analysis is ok! and that is so interesting to me  .



And after that according to the material examination reports, welding of a reinforcing bare is permitted by the engineer and its more interesting issue for me!

However my question is according to any fabrication standard is it possible to welding on a cracked surface material like that ?
(the depth of cracks are 3 mm in both sides and in all over the angles surface area .) 

Thank you.

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, ...
