Bringing back up this thread again to ask for your opinions. Could the problem be the brand filler rod? When I purchased the 4043 it was western alloy brand. A guy working at the welding supply I go to told me that Lincoln was a better quality. The welder he knows only uses that brand cause it was a...

Has anyone had any experience welding on aluminum that has been furnace brazed? I have been told that the radiators on dirtbikes are furnace brazed when the are built. But it's common to add some bracing or weld up the tanks on them. But it's a real pain in the ass and very difficult to have a good ...

Righton - I will keep working on the 4043 and try to improve! Thanks again for all the help and suggestions!

That's the same thing.

Well is didnt know exactly why it was listed like this in your post -

Filler metal type MIL-4043, ER4043, or 4043

please excuse my ignorance.

Tell me if this is correct- you are using ER-4043 filler metal? My shop has one qualified process using this filler. The parameters are as follows: Aluminum/aluminum based alloys, similar base metals (or base metal repair) Base material type Aluminum castings thickness range 0.060" - 0.500&quo...

For what it's worth, I've seen a lot of parts ( pressings and machined pieces ) in Europe welded with 4043 that have the surface appearance the OP is questioning. And these are welded by guys who are full time welder /fabricators. I'm wondering if it's in the rods, as here the 5356 also finishes cl...

Ahhh righton. Its set on square wave now. Balance 60 Freq 200 amperage 110 for the 1/8th material. Forgive me for not letting the initial puddle "clean" enough and when I went to add filler it doo doo'd up on me. The last pass I made sure I waited longer. (working on building up the end so...

You know whats weird, some times its purple, sometimes, gold, sometimes silver. Seems the lower amperage it doesn't get as hot. And soon as I lay a bead on the 1/8th material and bump up the amperage it changes colors. Is it possible for it to go back to silver after its been purple already on it ow...

Here are some pics of a few passes this morning. Balance is set to 65 Freq 120, Amp 110 - material is 1/8th thick 6063 square tubing Bottom two settings were before I checked my machine's user settings. The base setting for my tungsten size was not set to 3/32 and thats what I am using. So I fixed t...

For limited aluminum experience I'd say you were doing really well - don't judge your weld against perfection created by a welder that welds aluminum all day everyday ! Observations on bead appearance ( & I don't do enough to be happy with my own ! ) - all your settings sound about right or at ...

I have been searching the internet high and low for anything that can be causing my problem. I have had no luck! I have some 6063 square tubing, and some 5052 plate. I have been getting seat time on some of those two types of material I have laying around. I have very little experience welding alumi...
