Help Welding a Welder Cart

Quote:Hi Rick,

I did ask, and I was referring to the drawing that Ed posted in post #36 the left hand drawing. There is always that "big gap"......... so I aim for the radius part and go from there.

Thanks Rick

Hello Dave
A good rule of thumb is to point the wire at whichever side of the weld has more mass/density, in this case it's the radiused corner as effectively there is twice as much metal there with two faces joining at the radius, the same is true when butt welding dissimilar thickness plates, point at the heavy plate.

Sorry Ed,
It makes more sense now though, but as you now know there is no weld prep required on that particular style of joint, the edge radius sort of provides the ideal weld prep, just as long as you aim toward the heavy side.
The radius is designed specifically with welding in mind, it is a sort of "happy compromise" between the radius required to form a good rectangle, that can also be formed in a tube bender and a weld prep shape, as 90% of stuff made from rectangular tube has that exact welded joint and probably the same percentage of under 1" square tube products uses the radius formed corner bends.

Anyway, it seems my post was helpful so mission accomplished.

Best regards
Rick
