Was looking on youtube for tig videos and came across this one.
Can somebody explain to me what the heck is going on? If it wasn't for the arc I would have assumed that he had dipped the tungsten into the puddle and was trying to break it free.

 

where's is the link?

 

Ehhhhhhhhhh. I give it one minute and then I lock it.

 

oh crap, sorry, i'm finding it again

uh walking the cup? im guessin

 

^ yup.

 

what the hell...I watched all that and he cant even show us the weld. for all i know that was all show and he magicaly turned the pipe into a terd

 

I totally agree should of showed the weld.. it looked like he was rooting it with the torch..yeah walking the cup.

 

now i don't know what he was building, but why did it take so damn long?

Walking the cup due to impropper fitment?

 

I'd like to see some pic's of that weld, he was moving back and fourth way to fast to be walking the cup.

 

Well that explains why I didn't know what he was doing. I've been tig welding for the past couple years and still have no idea what "walking the cup" is. I have heard it mentioned many times but never bothered to look into it and the proper technique.

 

i understand the concept but i can't see why its used or needed, i too have been welding for a while now and i don't get it...it seems like i have only seen asain folks welding like that, i was watching some show on discovery and they were welding like that too ...i tried doing it that fast one day and couldn't get it to pool it just looked like what he was doing and produced nothing, but i can't say i knew what i was doing either

 

I walk the line, and drink from the cup, does that count lol

 

In my experience, it is used to avoid fatigue on thicker, v-groove pipe welds.
Never seen it used on a root, or without filler.
It's usually a smoother motion also. That was just weird...

If you do it the way pictured above, it looks like an aggressive herringbone weave.
I prefer the crescent weave technique myself.
Learn something new everyday!

I don't get why you would walk the cup on a fusion weld. Never seen that before!

i was thinking the same thing. I looks like sanitary pipe which is usually .065 most people free hand that shitt.

Walking the cup is usually way faster and more consistent for welding on heavier wall pipe. Any time im welding carbon steel or something bigger then sch. 10. stainless pipe im walking the cup.

 

ok what exactly is walking the cup? just welding in a zig zag movement is what im getting from this thread. anybody?............. and whats the point? bridging gaps? more weld surface?

Pretty much zig zagging, search on google you will see steps. As for the point, many people will say it does not help, but everyone has there own methods and feels what is stronger and what not.

Walking the cup is resting the cup on the base metal and twisting it back and forth to make it walk up the pipe. Its hard to explain unless you can get a good look at it.
The point is its usually way faster and more consistent when you welding a heavy walled pipe. Personally i would rather walk the cup because i can get a more consistent bead vs. free handing. But ive seen some amazing welders in the feild who have a steady hand and would rather free hand it. On H-T you wont see it that much if at all (excluding RC whos shitt looks real good) because nothing has a wall thickness bigger then sch. 40.

 

Well said, and thanks for the compliment. I free hand on thinner stuff, I just feel walking the cup provides a thicker bead and helps spread out the stress on that joint.

 

RCautoworks, when your walking the cup like that, are you adding filler?, and are your amperage settings different if you were welding the same piece walking the cup vs. freehand?
