ess, it is good to fix the workpiece with a
device. Avoid stiffening the welded structure
to prevent cracks in the weld. These pro-
blems can be avoided if there is a possibility
of turning the workpiece so that the weld
can be carried out in two passes running in
opposite directions.

Welds on the outer edge
The preparation for this is very simple.
V
However, it is no longer expedient for thicker
materials. In this case, it is better to prepare
a joint as shown below, in which the edge of
the plate is angled.
W
Fillet weld connections
A fillet weld is created if the workpieces are
perpendicular to each other. The weld should
be shaped like a triangle with sides of equal
length and a slight fillet.
Welds on an inner corner
The preparation for this weld joint is very
simply and is carried out for thicknesses of 5
mm. The dimension “d” needs to be reduced
to a minimum and should always be less
than 2 mm.
X
However, it is no longer expedient for thicker
materials. In this case, it is better to prepare
a joint as shown in Figure W, in which the
edge of the plate is angled.
Y
Overlap welds
The most common preparation is that with
the straight weld edges. The weld can be
released using a standard angle weld. Both
workpieces must be brought as close to each
other as possible.
