as per the standard the Aluminum is not preheated and the maximum interpass temperature is 120 degree C.
but do I need to preheat it before welding as the weather is +5 degree C maximum here.
best regards and many thanks
Elshan.

Hello Elshan ,
You may try the following:--
Ø Change the filler wire to 4043 ,as the filler contains slightly more Silicon, it would help in the weld puddle, with good fluidity and wetting.
Ø Use the correct mandrel diameter for bending Aluminum, check with ASME Sec-IX-, QW-466.1 for the correct mandrel diameters. As this alloy (6082-T-651) is aged after solution treatment , ductility is generally at the lower end(poor).
Ø If you can get alloys with lower iron content ( Fe typically 0.5 max) it would help. Iron generally reduces ductility, through formation of second phase ,such as intermetallic phases (see the attached document FYI)
I hope the solutions mentioned above would help you. Feel free to share your further experiences on this issue .
Thanks

Dear friends,
I need to run the new WPS in Aluminium steel plate using the attached grade of Aluminum plate.
How many times I have tried but I can not get the acceptable results from bend test.
It is broken after slight bending.
Can you help me please how to weld it to get the acceptable results from bending?
The wire I am using is ER5356 which is recommended for this type of AL.
Best regards,
