Welding multiple seams
The pin-filler distance should be about the filler diameter.
The filler should be put tightly against the privous seam.
Set Filler Function:
To get an even and flat welded
surface, we can pre-weld the
fillers, as shown in the left
picture.
There should be a distance about
the filler diameter, between two
neighboring fillers.
During TIG welding, the fillers
will melt and fill the spot
between two neighboring fillers.
Welding on Corners and Edges
The Start of a Corner
Welding on corners and edges is
a more difficult task than to
weld on a flat. The most
common problem is that there is
undercut (workpiece molt more
than welded on) at startup. We
shall give a few guidelines that
can be used.
