Subject: Request for technical paper

Dear friends,

I am glad to inform you that the Mumbai branch of the Indian Institute of Welding is organising the National Welding Seminar

(NWS),2009 from 4th to 6th February,2009 along with an exhibition ( WELD INDIA,2009) on welding, Cutting and its allied

products from 5th to 7th February,2009 in Mumbai.

The Seminar aims at discussing the Research & Developments in Welding Science and technology, introduction of high productivity welding processes , cost effective designs & reliable quality control methods along with the Mathematical Modelling and Simulation Related To Welding.

The core industries, viz. Coal, Steel, Power, Fertiliser, Mining, Railways, Oil & Gas, Cement, Fabrication, Capital Equipment, Petro-Chemical, Defence, Heavy Engineering along with supporting ancillary Small and Medium Scale Industries have been invited to participate in the Seminar as well as the Exhibition.

One copy of the brochure for the Seminar was sent to you long back. If you have not yet received the same, the same can be sent again if known.

I shall request you to kindly participate in the Seminar and present a technical paper in the seminar,. the subjects etc. of which are given in the brochure. The last date of receipt of the Abstract is 30th September,2008.

The abstracts may be sent by FAX , e-mail or post at the following address .

Mr. Dileep Kulkarni, The Chairman, Technical Sub-Committee,

The Indian Institute of Welding,B-101 Hill View Apartments,

L.B. Shashtri Marg, Vikhroli ( W ), Mumbai 400 083.

FAX : 022- 2579 4252 . e-mail : iiwmum@mtnl.net.in & dileep.kulkarni@hed.ltindia.com

Awaiting an early communication.

Thanking you.

Yours Truly,

N..K. Sarkar,

Organising Secretary, NWS 2009.

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...
