Question Proper Technique for Welding On Bullet Hinges

This is in regard to welding on bullet (lift-off, slip) style hinges that allow a ramp or gate to be lowered on a utility trailer. I have seen them welded in various fashions. With the questionable quality of the welds seen.....I thought I would as how they should properly be welded on.

Pics show the shapes of the hinges I wanted to see how y'all would position the hinge on the gate and trailer, itself, and where to place the bead. And, I guess I am asking Proper Orientation of the Flat/Triangular Surfaces of the Hinges

Thanks for the help.
ps-I think I got the photo rules. If not, let me know.

I don't know what the textbook way of doing it is, but if it were me i'd put the point of the triangle/bevels against the door/frame. That would stand the hinge out so you could run a filet weld down each side and get full, or almost full penetration.

I agree with Matt. Those hinges are designed so that you can weld them on and still maintain some clearance so that the gate (or door) will open w/out rubbing. On a trailer gate I'd position the gate where I wanted it, then put the hinges on with the elongated sides touching the gate and the frame. Weld on both sides if possible. The elongated sides are just to take up space and don't necessarily have to be in any certain position. Just put them however they will work.

Ditto Matt. Also, if you are putting one on in the opposite direction, so it is not a lift off type set up, then grease 'em good first with anti sieze.

If I am using them in a non removal aplication I drill the end and install a zerk.
All i do is insure adaquate clearance for operation and don't weld both parts to the same side of the opening. I have had several jobs to correct this problem the installer just leeps on welding

There are three ways to properly weld the bullet hinges on. Heiti looks to have covered the best way (in the link he posted with the pics) to weld them on. Just make sure you have them turned opposite ways so the lift gate cant fall off. Get some with a grease Zerk. And make sure they are load rated for your application ( I known the American made ones will say the load capacity, but the Chinese ones do not).
