Welding 5083-H323 Aluminum

Date 02-06-2008 14:57

We just got a contract to build some parts that are made for 5083-H323 Aluminum. We have never welded on this type of material. We are used to T6 6061 Alm. I would like to know what the biggest difference in welding this material is? Filler rod suggestions, shielding gas, difficulties, recomendations, experience, etc. I was thinking 5356 rod and 100% Argon. We will be using GTAW at the material is .125 thick. Any help would be useful. Thanks

Yeah thats high strength marine grade weather resistent aluminum correct? We use it on our aerial booms. 5356 is a good choice of filler and 100% argon for .125 thickness will do just fine and if you can weld 6061 t6 then you can weld this stuff. Whats the application for?

While 5356 is metallurgically compatible with 5083, (i.e. it shouldn't hot crack), it is lower strength. If you need matching strength, use 5183, and if you get too much dilution &/or a low alloy content batch of wire, it can still come in under strength.

I have used mini spool gun with .035.. 4043 wire with pure argon on 6061 and 5086 for boats and have had no problems so far.. I would like to here if any body out there if they have had any long term problems with this wire used an stronger metals. I have had no problems with cracking or any other issues so far thank you
