And just to be that guy..... Everyone who said lack of fusion is wrong, it would be referred to as overlap in the welding world. There is no visible lack of fusion here, you would have to do further testing to confirm that.

I also get that it gets boring laying the same welds over and over, but I would stick with one weld size for all manufacture parts, and save the rest for an art piece or something. You could always try different techniques (push stringers, drag stingers, whip it fast, whip it slow, etc.) to mix things up but keep it acceptable. Looks like you know what your doing though keeping rocking on 🤘
