Corner Edge Welding
Welding corner edge of work pieces is
easy to raise undercut in its top or terminal
part. As corner edge work pieces dissipate
heat is small, the focus of arc heating is
different between plane welding and
corner welding. The heating center of
corner edge can be a little focus on
electrode, while use high heat electrode
fluid to melt the sharp corner edge in the
work pieces. So, the two parts will be
merged together, which avoid undercut of
the work pieces.
5.3 Interior Angle Welding
The interior angel is the inclined angle formed in two work pieces which is equal or
less than 90 degree. If use normal welding method to weld, some bottom parts can’t be
welded well, especially in welding small parts. You should grind tungsten needle into very
sharp shape (less than 20 degree). The distance between tungsten needle tip and bottom
angle, side profile is very small, and then the two sides’ materials will be melted together
into the center part, and form a welding spot. If no welding spot formed in the center,
please try to remove tungsten needle to near bottom position, or try to increase welding
current until a welding spot formed in the center.
Next step is remove the center of tungsten needle to 1/2 position between welding
spot and welding edge.
