4.5 Joint--tracking
The joint--tracking equipment can be set for different types of joint--tracking. It can be
set for joint--tracking with edge control and for joint--tracking with groove control. The
setting is made both on the control box and on the sensor.
4.5.1 Joint--tracking with edge control
The following functions are set on the control box, or depending on whether
right of left--hand control is required. The two stop screws on the sensor should be
screwed in to the stop point. See the illustration below. This means that the fuses are
spring--loaded laterally and edge control is allowed. Joint--tracking with edge control
is used for welding fillet welds and similar joints, see also the joint table on page 98.
The stop screws are tightened to the stop point.
4.5.2 Joint--tracking with groove control
The following functions are set on the control box, or depending on whether
both vertical and lateral control or just vertical control are required. The stop screws
on the sensor must be screwed out at least two turns or to the stop point, see the
illustration below. This releases the spring loading for the search fingers laterally and
enables groove control. If the stop screws are not screwed out then there is a risk
that the search fingers start to ”climb” up the joint walls in shallow V and U--joints.
See also on page 98 for selection of setting.
The stop screws screwed out 2 turns
