[MW:3282] Re: [MW:/] Re: application of SS Flux cored wire for GTAW, SFA 5.22

By Materials & Welding
Sir,

May I know the thickness of the pipe and of grade of SS? 

I do not have any idea of Kobelco or Metrode product. In my opinion, Magna 39FC TIG will be able to do your job without Back Purging. The product is expensive but it is designed for jobs which cannot be back-purged or even sometimes even to eliminate back-purging setup. It will leave a very fine Slag in the inside of the pipe  which will easily come off with a little tapping after welding. And offcourse the slag can be easily drained off with water. The weld will pass X-ray.

Its best for the root, rest of the fill-cap can be done with any wire. 

If you are interested, contact me, i should be having its literature OR you can check www.magnagroup.com

Regards

Since purging option is ruled out due to space constraint. that is the reason for switching to flux cored wire

Hi,

I have tried in the past for mock up using Kobelco and Metrode GTAW Flux Cored wires. At site it depends upon accessbility of weld joint and welder skill .

If possible , purge the joint with argon / nitrogen and weld with GTAW flux cored wire .

Regards,
Alagu

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

By Materials & Welding
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

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...
