Re: [MW:29124] Re: Welding consumables certification

By Materials & Welding
This is contractual agreement before procurement.

So, owner already requested for 3.1 and you procurred 2.2? or owner requirements are same as your procurement?

Check the root cause and make correction, if its your correction then ask for the same heat from manufacturer which they shall have the tracebility but anyhow you have to provide AI representative, as for as 2.2 to is an non specific inspection requirements.

If owners correction then no need to provide anything so check what was in bidding stage prior to procurement for actual requirements.

Thanks.

Subject: [MW:29117] Re: Welding consumables certification
The certification requirements are laid down in  ISO 14344. The manufacturer is responsible for the compliance to the certificate and the manufacturer specify the quality requirements in their QMS. Now:
The welding consumable manufacturers provide filler wire with 3.1 for chemical i.e. actual results of the chemistry performed for each lot.

2.2 For mechanical properties which are typical values i.e. the stated minimum mechanical properties by the manufacturer.

In your case, you can ask the manufacturer to provide you 3.1 for chemical and mechanical both although it gonna cost to higher due to added cost to the manufacturer. Also it depends on your total requirements as for small qty. manufacturer may not entertain the requirements.


Thanks & regards

Dear Friends
 
As per our client specification for all welding consumables has to be minimum of EN10204 3.1 certification is required.
we are submitted EN10204 3.1 Chemical composition and for mechanical properties EN10204 2.2.
But Client not accepting that certificate due to mechanical properties has to be certified as per EN10204 3.1
 
let me know what is the difference between EN10204 3.1 and EN10204 2.2

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...
