Hot and fast is key to minimizing distortion. Here’s a .035 bead with wire feed speed turned up as fast as my machine will go.

I’ve never welded a day in my life, but that looks like great penetration in the weld!

WOW those are some impressive welds for sure. My favorite part is that you wrote your dope down on each coupon, very smart.

I’m just curious how much said product is going to weigh !!!
Not sure what you’re referring to?
The hull your welding !!
Scroll up to July 25th, there’s a spreadsheet.
Experimented with .030 and .045 wire and it looks like .035 is the sweet spot. Measured the actual wire speed for my spool gun, it’s about half of what is indicated (i.e. the 512 ipm I have dialed in is actually closer to 250 ipm). Now that the middle of beads look good I’m going to work on starts and stops to reduce the amount of work to blend them together.

Next we need some “break strength” tests!!
My old instructor would put our work in a vise and beat the devil of it.. Not sure how scientific that was, but when the vise broke before the weld, that was a guaranteed A..

Not too shabby for a “rookie!”

Very impressive bend test!

I spent the last week or so focused on the start of my welds, getting better coordination between arc detection and motion. I started out with 350ms (over a quarter of a second) of delay between arc detection and motion start. I was able to reduce it to a little over 1us (one millionth of a second). I’ll coordinate the end of motion with the arc next, then put the new capabilities to work.

Very cool to see all these DIY skiff builds mature!
