Re: [MW:31915] Welding of Trunnions Brackets Assembly Q355C & 42CrMo

By Materials & Welding
42CrMo H+T (EN 19)  to  Q355C (S355)  - This is welding between Tool steel and   Structural steel.

WPS of S355  to  API X52 can not be used for above combination of Tool steel and   Structural steel. 

You can do following - 
Weld  a  @ 300 mm fillet joint  of  42CrMo H+T (EN 19)  to S 355  using E8018-B2  with pre heating @200 Deg C  and cool under insulation.
Do Macro test - 5nos

Dear Experts 

 

we had design one Bracket assembly for holding one Hammer trunnion 

 

the Pin is grade 42CrMo H+T (EN 19) and bracket plates are grade Q355C (S355) 

 

Project is asking for WPS/PQR for these 2 materials welding together? and we have only WPS/PQRs for S355 and API X52 

 

You feedback with references will be highly appreciated

 

Regards,

HA

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, ...
