Aluminum TIG weld cracking

This is the bottom haul of a boat, have cleaned the area, using 4043 filler
and
an Aerowave machine at 55% electrode positive, shielding gas is argon.
Cracking along the edge of the weld, length wise.
TIA

I think that for marine applications 5000 series alloys are more common. Try switching filler? Stitch the weld instead of one long hot bead.

Marine aluminum is usually 5052 and is welded using 5356 filler to maintain salt water corrosion resistance.
It sounds like you are welding too hot.

Yeah, maybe too hot, or not adding enough filler rod to the weld. (or there were other cracks not yet visible until welding......)

Used 5356 filler and passed die penetrant test, thanks for the advice.
