I've done welds like the last picture, did have some help from a welding robot though
Totally agree..but to achieve a pretty weld like this do you think you could run the tig as fast as all the tacky weavy miggy stuff here?If mig isn't at least 6-8 times faster than Tig on a mig application then something is not right.

"On Aluminium a slight back weave can in some cases help with the weld integrity as apposed to being detrimental. It can agitate the pool more and increase the degassing time which can lead to reduced porosity levels"
Ooh I say.
That actually makes sense even to me.
My point exactly! there must be a pause in there somewhere!The set of photos in the first post look like separate welds on top of each other, in Matts process above it looks like a continual process.
If you read through ZTFAB"sDescription of his technique, His welds are done continuously, Not stop start pulsing with the trigger, Other forum members have seen him weld and verify thats true.Also not a weave but a whip back and forth using a pull direction.
When you weave with MIG the danger is that you do not get decent fusion at the root
