Internal corner joint
This joint is very simple to achieve, and is used for
materials with a maximum thickness of 10 mm.
The value of ‘d’ (see illustration) should be kept to
a minimum and should always be less than 2 mm.
Overlap joints
The most common preparation is with right angle
edges; the weld is completed with a standard
angle weld. The materials must be as close together
as possible.
Flat butt joints
The weld must be performed in a single operation
with sufficient penetration of the base material.
For this reason it is important to prepare well.
• The factors which affect the quality of the weld are
as follows: the current intensity, the distance between
the edges of the materials to be welded, the inclination
of the electrode and the diameter of the electrode.
• The electrode should be inclined at approximately
45° / 55° to the horizontal plane going through the
axis of the weld. Keep in mind that increasing the
inclination increases the penetration and vice versa.
• To prevent or reduce deformation which can arise
during solidification of the material it is advisable,
wherever possible, to fix the workpieces in a clamping
device or similar which exerts force in the opposite
direction of the expected contraction or deformation.
• Avoid stiffening of the welded structure to prevent
breakages in weld. These difficulties can be reduced,
if it is possible to rotate the workpiece so that the
structure can be welded in two opposite places. In this
case the electrode must be kept inclined at 50° / 70°
to the vertical axis going through the joint. Advance
steadily with a light cross oscillation.
