Welcome to the X3M TIG channel.
In a previous video, I showed the difference between TIG, and stick welding techniques.
And some Tips & Hacks That Work Extremely Well in the welding shop.

Today I will show you the difference between Stick and Flux core welding techniques.
We got two butt weld joints on a 4" carbon pipe
As I explained before, feather out all tacks, so we can weld root in one pass with no stopping.
Welding TIG on root pass with this technique will give us much-needed speed.
As you can see in this example grind tacks so you got both ends thin and thicker in the middle
This way it will help you to tie in smoothly and for uniform continuation on your root pass.
I'm using ER 70S-6 TIG rod and 140 amp
Start on the middle of the tack, "thicker part"
and when you tie in pause a little bit, to get that blend, smooth transition.
Very important to position your torch at 11 o'clock and be consistent
also good foot-hand coordination while in positioner roll welding
This part of the process is "crucial"
I will do hot and fill in one pass but leave a little groove, don't fill straight to the edge
I like to do the opposite as what I showed here, keep your torch at 10 o'clock
Positioning your torch at 12 o'clock is good for a quick hot pass
In this case, we need enough filler deposit that will handle 250 amps for stick
so we don't get any Burn-through
This is what you need, enough material and it's not flush with the pipe
When capping with stick technique
The inclination is important to reduce welding spatters.
Keep your rod at 12 o'clock with a 20-30 degree angle
If not sure about amps for welding, always a good thing to check is manufacturer recommendation
Slightly motion with your rod just enough to cover your edges
Keep an eye on your puddle behavior, so you can do little adjustments if needed
Like, inclination, speed, side to side motion, amps, ext.
I like to grind stop-start when stick welding, good habit especially if you not so experienced
Use a wire wheel to get rid of any spatters, it is easier when is still hot, no need for a grinder.
I like to grind tie-in or make a button, it's an old school way where you place your welder's stamp
Not allowed anymore, just markers for your weld ID
OK, now will do the Flux core welding here...
Position your torch at 12 o'clock
The advantage of flux core welding is speed.
and simplicity of using it.
I got a 10 mm stick-out, and NO side-to-side motion was needed.
Just watch your puddle as it spreads and covers both sides equally.
The important thing here is your positioner speed settings and foot coordination, and that's it.
Another thing tho, there is no need to grind the stop-start point, as you connect to your tie-in.
The flux core welding process is the fastest way for welding shop production.
Honestly, I'm not a big fan of flux core welding or being a part of the welding shop mentality.
I am a field welder, and TIG is my favorite procedure.
But to be a good welder, you have to be a complete welder, knowing all procedures and techniques.
So, the conclusion at the end. Flux Core welding is the fastest and easiest welding procedure out there.
