Re: [MW:12952] How can welding in very high magnetic fields?

Dear friend,

If there is magnetic field, we have to create magnetic field to demagnetize the area, any way as you mention for plate, i donot know how was it shape, if it is section wise, we have to do section wise magnetic field, then those demagnetise, tack wled it, but sure before another piece , you have to sure demagnetize plate shall not re-magnetize again by coil, check with filler wire or any plate, if once re-magnetise again , it will not easy to demagnetise. i face so many time same this type of problem in my previous project..

if any query kindly contact.

Hi Madhu

Thanks for your attention
But there is not a pipe for welding, We have about 13000 succession (series) of plates that must be welded to a ring-shaped shell with about 5000 mm in diameter of shell and about 15000000 mm in diameter of ring.

make a coil around the pipe with dc supply with + or - polarity , it automatically demagnetise, then u can easily weld.

I was face same problem before in existing line.

Dear all
Hi,
We have a bed problem in my project.
The fact is that, we must welding CS plates in location that, there are a very very high magnetic field intensity.

This magnetic fields created by other equipment's that are the near of my CS plates.

Best Regards

Re: [MW:34105] SA266 GR4N 4 Cycle SPWHT

Hi, You are correct, Minimum refers to the one cycle for which this part will expose until final work shop PWHT. hence mill test certificate shall include this. Max. SPWHT, refers to additional cycles of heat treatment that are reserved for future repairs during equipment lifetime. Again, these simulated no. Of cycles shall be specified in MTC. The idea is we need to make sure that steel mechanical properties are not compromised upon exposure to multiple repairs (i e 4 cycles in your case). One could say, if steel is subjected to 4 cycles and is ok, then it should by defacto be good for one cycle, yet, this is wrong assumption cause mechanical problems and microstructure of materials varies accordingly based on no. Of cycles for which material will expose. This is apparent in alloy steel and especially for impact test values as an example. In your case, this forged CS with properties before PWHT can be understood to be " as forged" condition (i.e. Wit...

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...
