Welcome to the X3M TIG channel.
So, what do you think, is this cap?
Or maybe not?
In this video, I will show you how to weld with Hi-Lo
and have some fun with 3D outcome effects.
OK, let's dive into the details
I'm welding on 16" Sch.150 carbon pipe
After root pass is done, still have hot, fill and cap to finish.
But the little problem is here, we have Hi-Lo all around
Hi-Lo also called misalignment,
refers to the mismatch in height between two pipes lined up for welding.
On this side, we got more than 7 mm in height difference.
After Hot pass is done,
I will put a second pass, focusing on filling the Lower side,
Up to the edge of the bevel.
For my 3rd filler pass, I will fill to flush
to be completely level.
Filling to flush will help me to put a cover pass easily
and reduce that visible sloping.
Still, I got some inclined appearance.
But I also discovered a system, playing with my camera angle
that adds a three-dimensional appearance to the visual image
So If you guessed that was a cap in the beginning, well you were wrong.
Now I'm going to put a heavier cap on that filler pass.
Try to hold your filler wire on the upper side of the bevel
It helps when you trying to reduce that sloping.
It builds up the lower side by lifting up a little bit of your cover pass bead.
