Re: [MW:7408] Fwd: Welding of LTCS cast to SS 316 Plate

Hi,
According to EN15607-6.4 Qualification based on previous experience,Please refer qith EN15611 for the method of qualification reference to previous welding experience.
 
 
Since i dont have EN15611 i couldnot give you the suggestions based on EN15611.
 
Thanks & Regards,

Many thanks for answers.
 
Karthik,
 
According to EN ISO 15607, is it possible to waive the WPS? (Please see in below for EN ISO 15607)
My undrestanding for ASME codes, no way to accpet previous welding experiance. Please correct me if I am wrong.
 
Cheers,
 
"

In EN ISO 15607, one of the methods of welding procedure qualification is by relating to previous welding experience.

 

Many manufacturers have considerable experience in fabricating welded structures. Welded components and structures may have been supplied to end users/clients for variety of applications and have performed satisfactorily over a period of time in service. If this experience is traceable and documented this provides a route to welding procedure qualification based on this experience."

Hi there,
 
We have a situation, our Valve contractor want to weld jachket material which is plate stainless steel TP316 Eurpian standard to LTCS cast material ASTM A 352 LCB standard. The reference welding code will be Europian standard. We asked for WPS, and they provide us WPS for CS to CS material, & SS to SS material acomponied by PQR, but WPS for LTCS to SS material. We asked for LTCS to SS material WPS and PQR, and they replied that within Europian standard they never used such WPS. My quesion is, "Is this answer is acceptable?", what I know according to ASME Sec IX, for wach welding type we should have exact WPS and PQR, otherwise is not acceptable.
Could you please help me on this.
 
Thanks & Regards,
Parviz

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...
