Welcome to the X3M TIG channel.
For this video, I'm using very bad, and low-quality equipment,
but that shouldn't be an excuse to have a bad performance if you have skills!
Gap is 5/32
I like to use a Flexi head body tig torch, especially for fieldwork.
Angle the torch so that the front of the cup is touching the pipe
with the tungsten just slightly above the edge of the groove
At 8 o'clock reposition your torch so that the back end of the cup
is touching pipe and with tungsten slightly at the edge of the bevel.
Hold your torch at the very bottom of the handle
At the top or from 11 to 12 o'clock, let your cup seat in the groove
and with your wrist motion, left to right, walk that cup.
Soft grip and a light touch when you holding your torch.
Holding the filler metal gently against the pipe
And constantly feeding your weld puddle.
Angle your cup so the Tungsten is very close to the puddle
But far enough to not get contaminated with melted filler wire.
Difference between freehand and walking the cup on the root
is that with walking the cup we got consistency in metal deposit
Walk the cup up to 8 o'clock with the lay wire technique.
Once you pass 8 o'clock and start claiming uphill
Pull your rod out and continue to hold slightly on the outside of the edge.
As you noticed at the beginning of the video I'm using scratch-start technology,
so grinding stop-start is a must.
115 amps
Usually the same amperage for sides and the top.
Make sure there are no obstacles in your groove
so you can easily wiggle your torch.
For the top part, I'll be using the dipping technique
And finish tie-in approximately one 1" further.
As you can here I'm dipping the rod into the puddle
While speeding up my move with a torch side to side.
That's how you prevent any "grapes" on the root
or even bigger gap opening.
Always pause on each side when you tie-in
Just to be sure you tie in properly.
For Hot pass same thing as for the root
With the front end of the cup, walk slowly up to 8 o'clock
After reaching 8 o'clock reposition your torch
You should be holding your torch at the bottom of your handle
The best time for practice is actually on the hot pass
Try to learn how to switch from the back-end to the front end of the cup.
While you welding
Mastering that skill will give you advantage
to finish any welding tasks way faster.
Hope you liked this video
and learn something new
