[MW:25784] RE: 25779] Limits of E6013 in pressure vessel (sec viii div 1)

Hi,

It is either 6013 or 7018 - whatever it may be, you have to establish a WPS and then qualify the PQR -

If all the particulars (mechanical, chemical and etc.) are complying to the specifications and to client requirements in the established PQR - then there will not be any issue of using any consumable.

Or...

If your client specification has called for any specific requirement of the electrode (say E 7018) then u have to qualify the PQR with that only.

Or...

If you have any constrain in using any electrode (practical problem, approach, easiness in welding, weld metal deposition rates, any power source limitations, any specific NDT requirement and many more particulars) then also, you may opt for 7018 or any other grade to suit requirement -

But in and overall - you have to qualify the PQR with all the variables...

Hope u understand...

Thanks & Regards,
Lakshman Kumar B,
Project Manager.

Dear sir,

In fabrication of pressure vessel from 10mm thk plate, would we allow to use E6013 electrode.

Is any where given in code of sec viii div 1, about limits of E6013, or only E7018 is allow.

Regards
Prasad Rode

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...
