9. Proper Welding Techniques – Drader Injectiweld – Fillet welds
Fillet Welds – Correct Alignment
Welding tip is in
correct alignment
when it is at a 45°
angle
Welding tip is in correct
alignment when it is at a
45° angle
Welding tip is in correct
alignment when it is flat
against both sides of the
parent plastic material
Welding tip is in correct
alignment when it is flat
against both sides of the
parent plastic material
When welding from one
side, leave a root gap of
0.8 to 1.5mm so that
welding rod can penetrate
to the other side
Welding rod should
penetrate to the root side
of the parent plastic
Fillet Welds – Incorrect Alignment
Welding tip is not incorrect
alignment when the fillet weld
tip is not at a 45o angle or
when it does not come into
contact with both sides of the
parent plastic material
Welding tip is not in correct
alignment when it does not
come into contact with both
sides of the parent plastic
material
Welding tip is not in
correct alignment when
the bottom edge is not flat
against the parent plastic
material
Welding tip is not in
correct alignment when
the bottom edge is not
flat against the parent
plastic material
Lack of penetration to
the root will result in a
poor weld
Since molten welding
rod did not penetrate
the root, a poor weld
will result
