The forging process is most often used when working with hard-to-weld materials such as
aluminum. The weld is usually made at the normal force, followed by the application of a
higher force during weld or hold time. This action may refine the weld zone, and provide a
more homogeneous weld nugget.
Timing of the application of forging force is critical. If applied too soon, the welding current
may be insufficient for the higher force. If applied too late, the weld will have solidified and
the forging force will not do any good.
Forge delay is defined as the delay from the beginning of the weld and the activation of the
forging solenoid valve. To accomplish a FORGE DELAY operation on EN1000 series
controls, it is necessary to chain together 2 or more SCHEDULES as outlined below.
1.
Program the first SCHEDULE with the amount of WELD time desired before the
activation of the forging valve. Use any one of the 3 solenoid valve outputs.
2.
For FORGE during weld, program the second SCHEDULE with remaining WELD
time and program an unused solenoid valve output. This second valve output is the
forging valve.
NOTE:
For continuous current from the first SCHEDULE to the second schedule, do not
program any HOLD time into the first SCHEDULE or SQUEEZE time into the
second SCHEDULE.
3.
For Forge after weld, program the number of cycles of time between WELD time
and the activation of the FORGE valve into HOLD time of the first SCHEDULE
or into SQUEEZE time of the second SCHEDULE.
