3.1  SYNERGIC  WELDING  AND  WORKPOINTS

Prior to using 

Wave Designer

it is important to have a good understanding of the concepts of

synergic welding and workpoints. Synergic welding is basically “one knob control” of a welding
process; all other variables of the process are adjusted by the power source based on the single
controlling variable. This single controlling variable is known as a workpoint. For example, in
synergic pulse welding (GMAW-P), the operator can adjust the wire feed speed (WFS). The
WFS is the workpoint. The synergic power source will then set all other GMAW-P variables
based on the WFS by “looking up” the other variables from a pre-programmed weld table. See
Figure 3-1.

Wave Designer

is a program that lets you develop a customized weld procedure by letting you

program each variable for multiple workpoints into a weld “look up” table.

Power Wave power sources go even a step further than simply “looking up” pre-programmed
variables from a weld table. If a selected WFS is between two pre-programmed workpoints, the
Power Wave will interpolate values for each of the welding variables. The result is a precise and
continuous range of welding control.

Refering to Figure 3-1, lets examine how this interpolation works by looking at one welding
variable — background amps. The operator selects a wire feed speed of 175 in/min. This value is
between the pre-programmed workpoints of 150 and 200 in/min. The Power Wave interpolates
between the pre-programmed background amp values of 80 and 60 and adjusts the background
amps to 70.
