    Might as well tig it if you want that look. This jod looks like a lot of spot stitching.
    Look even though.

    Very nice. Is that spot stitch?

    It looks good, However you should have used 53/56 on 6061 tube.

    I agree it looks like you stitched it, I worry less about the nice ripple and more on the good fusion.

    Wow. Thanks the first 2 guys. Ok,it's not stitched,there is maybe two start/stops which are blended pretty well. Next,doing TIG on 1" to 1/2" would cost quite a bit more not counting the hours of extra welding. In a high production shop,that's just not feasible. Next,this is not tube it is 1" plate,1/2" plate and I-beam. I don't know why someone suggested 5356,this is a Boatlift and a brittle wire would make no sense. And no it's not pulsed MIG and no it's not too cold and yes we do destructive and non-destructive tests regularly. Always complete fusion and always passes.

    I thought 5356 was the go to wire for structural aluminum like 6061.....4043 I generally use on cast or repairs....

    We use 4043 instead of 5356 for several reasons; better looking welds (as all lifts have quite a few through bolts),we do occasionally weld 6061 to cast which 5356 can't do,more penetration(while not as strong as 5356,penetration is key when welding 1" plate without much of a bevel or chamfer),our winch heads have motors that get got and 5356 will corrode faster if it's past 150 degrees (I could be wrong on that),no hot cracking(in my experience),the list goes on.

    You should switch to 4943 then. Bridges the strength gap between 4043 and 5356 while retaining the fluidity of 4043. Maxal makes it.
