GENERAL DESCRIPTION
FIGURE 1 ROTOWELD 3.0 WORKSTATION
The
ROTOWELD 3.0 WORKSTATION
is illustrated in figure 1 page 10. The
two major components are a positioner and a welding carriage, linked by a
flexible cable conduit. The carriage moves on rails parallel to the positioner's
axis allowing several welds along a single pipe spool to be performed in
sequence. The spool is supported by a set of idler rolls also guided by rails to
keep them aligned with the positioner's axis.
In the case of a Twin Workstation, there is an additional positioner mounted
on the same rail system therefore providing two independent workstations
sharing the same welding carriage. This allows off-line loading/unloading of
spools in the alternate work bay without interruption of the welding process,
thus maximizing arc-time.
The welding carriage consists of a base and a column on which a control
pendant, a monitor with the computer in the back, a torch manipulator with
oscillator and welding torches support (GMAW or SAW depending on the
model). The camera is incorporated just below the oscillator. In the base is
located the cooling water circulator. For SAW welding, a pressure flux system
(SAW fill model) is added at the back of the base carriage. The column
houses various controls, electronics, the wire feeder(s), the gas valves, the
flow meters, and the wirer spool(s).
The main positioners consist of a self-centering chuck and a face plate
