| TIG Welding 101 |
A welder once told me"Welding is like sex, it is all about using your
rod to achieve maximum penetration."
Penetration is the key to a good weld, if the metal just lays on the surface it will not
be as strong as one with deep penetration.
The first photo shows the top of 2 beads, one on the surface and the other on a seam.
The base metal should be melted on both sides of the weld and the filler applied to the
puddle. The weld should look smooth and even with a minimum of undercutting at the
edges.
The second photo shows the bottom of the welds, notice the metal has been melted
through. The seam could have used a little more heat and filler. if you have a wide gap
to fill back it with copper to keep air from the weld.
Now go practice!!!!!

With some practice you can lay down beads like
this. The welds look good enough you don't
need to grind them.
