[MW:5136] FW: 5105- ESSC

By Materials & Welding
 
Dear Mr. Singh,
 
Mr Prem Nautiyal had provided  very detailed guidelines on ESSC. The following documents definitely would be of interest to you. From my past experiences in application of ESSC, I have noted that it works extremely well with Magnetic oscillation especially with wider ( 5 inch) strips. The same may not be true with smaller strips, however would definitely be worth considering.  
 
 The last article is a good description on various pros and cons of this process.
 
Thanks.

Dear Mr.Amarjit Singh

I am assuming that you are using ESW (2 layers ) and not ESW(single layer ) OR ESW (high speed).

I strongly recommend that you use Soudokay consumables for ESSC.
Please visit www.soudokay.com for more details and in India you can get these consumables from Bohler Welding group.

The type of strip for 347 deposit is Soudotape 21.11 LNB and flux Record EST122.

Now coming to welding parameters for ESSC of 60 X 0.5mm strip :

1) current =1250A ( DCEP)
2) 24V ( voltage is governed by flux used and must be maintained within +/- 1V ).
3) Travel speed = 170mm/min
4) Bead thickness = 5mm ( less bead thickness will give poor bead shape and high dilution, while higher thickness greater than 5.5mm will give LOF at the overlaps )
5) Dilution % = 8-10%
6) Stickout = 25-30mm ( distance between strip end to contact shoe)Note that dilution reduces with increased stickout.
7) Bead overlap : 5-10mm.


Regards

Prem Nautiyal

>dear friends,
 
I have to carry out ESSC of SS 347 on CS with 60mm wide strips. Please suggest
 
1) suitable consumable combination
2) parameter for welding

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...
