Welcome to the X3M TIG channel.
So finally we have completed the milestone of 1000 subscribers on our youtube channel. 🤩
I would like to thank you all at this time. Thank you so much! 🙏
In the previous video, we had root pass in the 6G position.
I did the first pass or hot pass, and I will continue with filler passes and capping.
For the second pass, I'm using cup size #8 with 1/8 tungsten
I will wiggle the cup to do the second pass with side to side motion.
I'm running 150 amps on my second pass.
Filler passes are good timing to practice your welding to finish each pass without stopping!
It will help you later on a cap, for better looking, straight edge and uniform beads.
Don't know did I mention it, I'm using 1/8 filler tig rod ER70S-6
The second pass is done
and now I will put 3rd pass in.
I'm switching to cup size #10
Same thing as with the second pass
Wiggle your torch side to side motion.
Amperage is the same 150 amps
Now I got 3 passes in
Now is time to calculate your next step,
will you run through the middle one more time or start filling sides...
I choose to start filling sides, as it will take me less time to fill it to flush
Planning steps with multipass welding are a really important part of the welding process.
Time-consuming and fatigue, can impact your welding performance.
That's why I like to weld HOT and fast all the way to flush
Because capping is the cherry on the top and it takes lots of energy to do it well.
Now filling the other side
I fast forward a couple of passes.
Still filling sides to make it flush
This will be the 7th pass now, and it will be flush finally ;)
NOW
I will give you a Tip on what I like to do, REMELT your filler pass around NO ADDING WIRE!
This will give you a nice, even, and clean surface without impurities,
perfect base for capping, no impurities means, it is easier to push your puddle.
With the first pass, focus on having a straight edge.
At this point, the pipe is getting too hot, use a chain grip as it helps to place your arm, and have better control.
3rd pass is important same as the first pass, covers all imperfections on the second pass,
and straight edge makes a big cosmetic difference at the end.
3rd pass is more important than the first pass, as you got two edges to be a focus on.
It's cherry on the top
Capping is done
It's not perfect, I got a couple of spots that could be better, but an important thing is no undercuts.
