[MW:14561] 5083 (tempere degree 321) Aluminium PQR matter

Dear welding experts


I need to hear about the PQR of Aluminium 5083 with tempere degree
321.

5083 aluminium with tempere degree 321 has tensile strentgh : min. 305
MPa
ER5183 (commonly used wire for 5083 aluminium) has tansile strentgh :
min. 290 Mpa
(Even you use ER5556 wire tensile strentgh is min.295 MPa)

So i mean that if we use 5083 (tempere degree 321) aluminium base
material, even you use ER5183 or ER5556 you can not reach the tensile
strength 305 MPa in the weldment. So always tansile strength specimens
rapture from weldment.

If i make a pqr like this how can i accept it in this condition? I
mean the tensile test will be raptured from weldment ? Normally this
is a cause for fail for PQR?


( note: If we use 5083 with tempere degree 111 there is no problem
because the tensile strenth of 5083 aluminiım with 111 temepre degree
is 295 MPa. )




Thank you.

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...
