Re: [MW:3923] WPS & PQR clarification

By Materials & Welding
Dear Mahendra,
If you are running WPS for the first time then follow what other friends (
Daniek & Sukamal)suggested. Start with draft WPS , run PQR and finalize
WPS.
If you have many PQR`s in records from previous jobs/project within the
required specs and parameters, then you can issue a WPS based on the
existing one (s) and no need for a fresh PQR.
Regards

Fereidoun

Dear Group

Good day,
--------------------------------------------------------------------------------------------------------------------------------
Still I have confusion on WPS and PQR terms.

1. WPS to be created first , with respect to selection of process,
electrode and current etc.
2. PQR is developed after WPS ,by entering the the actual variation
relevant to the WPS.

|Corresponding reference numbers are to be entered in each other.

This is the information from ASME IX codes.

--------------------------------------------------------------------------------------------------------------------------
But there is a controvercial statement from some of our colleques, PQR to
be developed first and Supporiting PQR reference number is to be entered
in the WPS.

Please clarify this confusion .

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...
