I agree with those welds appearing cold. Turn up the amperage, or turn down the wire speed. And I'd also grind a larger bevel in the joint to ensure 100% penetration. Don't be afraid to make a couple passes too.

How thick is the wall thickness of those tubes? What welder are you using? Sorry if you've already stated - I couldn't find it.

The thickness is 1/4 I will try will add more bevel and slow the speed down and try it again that's why I cut that piece to practice on I'm a noob at welding so I wanted to get some practice before the real things it's a harbor freight 125 flux core welder the heat is all the way up. I'm a little concerned it's not gonna be enough welder for this job but I'm gonna give it a try! Thanks alot guys for your advice I truly appreciate it!
