Mechanized Welding Station
A mechanized station is used when the
work can more easily be brought to the welding station or where a
great deal of repetitive welding justifies
special fixtures. Arc travel is automatic and controlled by the fixture
travel speed. Weld speed is usually
increased and weld quality improved. As
shown in Fig. 2-3,
the welding equipment in a mechanized fixture is much the same as in a manual
station except:
1) The welding torch
is usually mounted directly under the wire feed motor, eliminating the need for
a wire conduit.
2) The welding control
is mounted away from the wire feed motor. Remote control boxes can be used.
3) In addition, other
equipment is used to provide automatic fixture travel. Examples of this equipment
are side-beam carriages and turning
fixtures. The
welding control also coordinates carriage travel with the weld start and stop.
