Weld Process
Overview
Synergic Welding
– Computer control of the welding arc based on a single user-defined characteristic (wire-
feed speed, material thickness, amps, etc.)
– Changing the wire-feed speed will automatically adjust the voltage necessary for the
filler metal and gas being used. This is done through the use of a digital signal
processor and a synergic line
– Provides an extremely high level of repeatability and precision
– The synergic line can be modified slightly to account for environmental differences
between laboratory testing and production
Synergic Line
– An arc-characteristic curve that links a number of welding parameters together giving
the most ‘ideal’ values for a specific filler metal, wire diameter, shielding gas, and
operating mode
– This line is created through a complex set of measurements taken while welding with
the specified settings
– A standard line can be chosen/programmed in a matter of seconds with the simple
selection of a few base parameters
TransSynergic and TransPulseSynergic
– Standard MIG power sources available from Fronius
– Both have the ability to do standard (conventional “2 dial”) welding and synergic welding
(one dial)
– The TransPulse Synergic power source has the added ability to perform pulse-synergic
welding
