Subject: [MW:20621] RE: 20620] Temperature Measurement in Submerged arc welding

 

Dear Sir,

 

There is contact free infra-red equipment temperature measurement equipment available with which you can measure the temperature during welding on a certain location. For myself I have these equipment which I can connect to my HKS Weldscanner welding data logger (especially for determination t8/5 in high strength steels). With this system you can put in a threshold temperature from which measurement should start (for example 250 °C) and then start welding. As soon as the welding arc reached/passes the fixed measurement location and the temperature reach the threshold temperature measurement starts and stops afterwards when temperature drops below the threshold value. The system can automatically calculates the time it takes to cool down from one pre-set temperature to another pre-set temperature. You will also get a graphic available afterwards.

Unfortunately I only have a user manual in the German language which I included as attachment for your information.

 

Met vriendelijke groeten / Best Regards,

Anyone can provide the idea to get the cooling rate through temperature measurement in submerged arc welding?? i need this for welding research purpose.

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, ...
