Re: [MW:22978] PQR without impact test

specify ur impact requirement....

Two assumptions:  1)  the applicable Code is ASME Section IX and 2) you are using GTAW to run the root and/or hot pass.

 

If the above is true, unfortunately, the answer is no – you will have to perform a complete qualification test.

 

Once you have impact testing as a requirement, you must apply the supplementary essential variables for the process.  For GTAW, one of the supplementary essential variables is QW-404.12.  This variable states that requalification is required when there is,  "A change in the filler metal classification within an SFA . . ."  The exceptions, (a) through (f) do not apply to your situation.

 

Good luck – hope this helps.

Subject: [MW:22968] PQR without impact test

 

 Dear expert ;

 

we have a WPS and PQR for A333 Gr 6 welded with ER 70S-3 and E7018 , the mechanical test in the PQR are only tensile test and bend test.

 

Our client didn't accept the PQR because is missing impact test and he ask to repeat all the PQR with all mechanical test ( with ER70 S-6 for better impact test result ).

 

it's possible to keep the PQR and to make only the impact test ( we can weld a 6" pipe according the WPS but with ER 70 S-6 and take specimens for impact test ). ????

 

Regards

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...
