RE: [MW:3929] Welder Qualification

By Materials & Welding

Dear Roshan

As per Sex IX, QW306 Combination of Welding Processes

 

“Failure of any portion of a combination test  in a single test coupon constitutes failure of entire combination”

So if one welder out of two is failed, when the test is conducted in single test coupon then the entire test is considered as fail / fail to meet the requirements of Sec IX.

 

Thank you

Regards

Harikumar.

Subject: [MW:3928] Welder Qualification

 

Dear all,

 

Here we have a situation,

 

1) welder qualification conducted on 24" pipe as per Sec IX and client requirement(PDO SP-1096) with two welders welding from opposite sides( one welder welds the half portion and the other half by another welder).

2) RT accepted for 1st half of the portion, but the other half fails to meet the requirement.

 

Question: Whether the test coupon shall be sent for bend testing to qualify the welder who welded the first half?

 

 

NB:RT & Bend test required as per Client requirement.

 

Regards

 

Roshan

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...
