Sliders not welded on right?

So previous owner had some sliders welded on. The were originally bolt on sliders..
Do they look right or do they need to be redone? There is a slight gap between the place where they are welded on and the frame.




This is the one closest to the bed. On both sides it is the only one where the top is welded but the bottom is bolted

Closer inspection.. It's pinch when jacked up

 

It would be generous to call those even tacked on.

 

I saw this pic and couldn't help but feel like mine were done wrong..

 

Fucc me.. There's always something

 

Nice work. I'd like doing those scab plates a little differently but it would be serious nitpicking.

 

Welded on? Didn't see a single weld.

As far as hitting the pinch weld, that's going to be common practice depending on brand. Some try to hug it as much as possible. Some people even pound it back.
