    Default Tig welding 5052 Aluminum. which filler ?

    guys,
    we have a small project at work we will be tig welding which is made from .125" thick sheet metal, the alloy is 5052 aluminum.
    i searched the internet and see its safe to use 4043 or 5356 filler, which we already have in the shop.
    do you guys agree with this ?
    and is there anything special i should look out for when welding this type of aluminum ?
    thanks for any input, since i have never welded 5052 before.

    Either filler is good unless you are anodising it then go for 5356.
    4043 will be more ductile and less likely to crack but on the other hand 5356 is a stronger material but tends to crack if you don't cap the weld properly.

    5052 is also used a lot in marine applications. if it was going to be exposed to the elements i would use 5356. But as stated before either will work.

    thanks for the help guys.
    since it wont be getting anodized, i will go with the 4043 to stay away from the cracking...
    again, thanks much

    It would help to know what the project is. If it is something that is going to experience high temperatures, 4043 would probably be better. If it is something that needs maximum strength, 5356 would probably be better.

    5356 is actually more ductile, whereas 4043 may be a little softer, but will fatigue much faster than 5356 or 5183. I would never use 4043 on a seam that experiences vibration or variable loads.

    If you are welding 5052 sheet into a tank, you are much better of with the stronger filler. Personally I choose 5356 every time unless elevated service temps are experienced.

    Lately I have been using Maxal's 4943. Lightning fast for tig work, and bridges the gap in the strength area. Wets like no tomorrow.

    So there are some people using 4943. Shovelon have you been using it for just tig or mig also? Also what type of application? I've talked to my lws about bring some in for use on 6061-t4&6 plate for making race snowmobile engine mounts. From what I've talked to maxal it should be the cats a$$ after post weld tempering.

    I haven't seen the 4943 on the AlcoTec Filler Alloy Chart, what alloys is it most compatable with? Going to have to do some research on this filler.

    4943 is a Maxal product. You won't see it from anyone else. It is compatible with any alloy you would use 4043. Maxal's website has a lot of data for it's use.
