Section III. Welding Capabilities
Opposed Welding
With opposed welding, the top and bottom electrodes are used to hold
the parts and provide the current path. Weld current flows from one
electrode through both parts to the other electrode.
An opposed weld is preferred over other configurations because it is
easier to set up and the current path is more easily controlled. It should
be used whenever possible.
Dual-Opposed Welding
This method of welding uses two opposed welds being made on a
single part, using two separate weld energy power supplies. Weld
energy can be delivered in a simultaneous or alternate fashion,
depending on your manufacturing requirements. Opposed welding
provides maximum weld strength repeatability.
The Table Electrode, or a user supplied fixture, acts as a support for the
workpieces in step welding. If the Table is insulated from the
workpieces, there is no possibility of shunting current away from the
(-) electrode.
Series Welding
In series welding applications, both electrodes contact the same surface
of each workpiece. The weld current flows from one electrode through
the workpiece to the other electrode. This technique is used to weld
workpieces which have only one surface accessible.
The work surface, or a user supplied fixture, acts as a support for the
workpieces in series welding. If the Table is insulated from the
workpieces, there is no possibility of shunting current away from the
(-) electrode.
