But Why?

Rocky D in your post "Different Kinda Gate" why did you use a (for lack of a better term) spot or start stop TIG on the hinges?
You used this for the hinge only and the continuous welding on the other tig welds shown.
I saw a similar start/stop welding on an Orange County Chopper when welding a frame for a motorcycle.
When should one be used over the other technique?

I think you are referring to this hinge..this is a MIG weld not TIG, but if I had welded all the way down, the gate wouldn't open, because I would have welded both halves of the hinge. :eek:

I think your question is "when do you use a skip-weld technique?"

Good question...there are situations where a continuous weld can weaken the part or it is just not necessary, since it won't add any strength to the joint.
Weld placement is an acquired skill, and hard to describe in this manner here.
Skip welding call outs are like: 2 on 4 staggered...2 on 4 back to back and so on. This is where books come in...they will have a picture describing all of this. There is a lot to know about this stuff, and if I haven't answered your question, ask again and I will re-focus my answer.
Please don't use OCC as a teaching tool! :eek:

Thanks, you covered it. I will have to look for better welding technique publications, do you have any suggestions?

I haven't used a welding book, since the Army TM's in the '60s, but there is some good educational materials on the Miller website.
