Appendix A A-3 PULSE W A VE SHAPING PRINCIPLES WAVE DESIGNER • From time T1 to T2: Background current maintains an arc, and a weld bead starts to form.
A.3 AD APTIVE AND NON-AD APTIVE MODE To proficiently develop welding procedures using Wave Designer , the key concept of Adaptive versus Non-Adaptive welding must be understood. Wave Designer allows the user to set the machine into either adaptive or non-adaptive mode.
A.4 PULSE W A VE DESIGN PROCESS The Wave Designer software interfaces with the welding machine controller to permit real time communication of pulse wave design changes. Refer to paragraph 2.3 for equipment interface connections. Use the following wave design process to customize a standard wave shape.
A.4.1 SELECTING A ST ARTING W A VE SHAPE When customizing a waveform for a specific welding application, we recommend that you use a waveform in an existing weld file. An existing weld file can be selected from the systemWeldFiles folder in the Wave Designer directory as follows: a.
NOTE: You can edit one or more workpoints to values other than the defaults. However, the listing of wire feed speeds displayed must be the same or increasing from top to bottom. All twelve wire feed speeds must be assigned values, but multiple workpoints can share the same value.
2. Open the Adaptive Loop / Find the Optimal Ar c Characteristics Use the following weld trials and adjustment sequence to tune the selected waveform for your weld application at the designated workpoint (wire feed speed).
3. Close the Adaptive Loop / Adjust the P eak V oltage a. If the adaptive stickout window is not open, click on the button to open the window. Select the adaptive option to close the adaptive loop.
5. Adjust the Start Control P arameters (Optional) The start control parameters can be adjusted to define how the welding machine will respond when the arc is struck. To view the start control window, click on the button on the Waveform Editor screen.
6. Adjust the Shorting Control P arameters (Optional) The shorting control parameters can be adjusted to define how the welding machine will respond when the arc shorts to the weld puddle. To view the shorting control window, click on the button on the Waveform Editor screen.
7. Adjust the End Condition P arameters (Optional) The end condition parameters can be adjusted to define how the welding machine will respond at the end of a weld application. To view the end condition window, click on the button on the Waveform Editor screen.
8. “Go Figure” / Make the W avef orm Synergic Weld synergy is established by shaping the 2nd and all subsequent workpoints. Being synergic, the waveform parameters automatically adjust to programmed data table values. The data table values are unique for selected wire feed speeds.
A.5 PRIMAR Y PULSE W A VEFORM COMPONENTS The following paragraphs describe how peak current, peak time, frequency, and background current effect weld droplet transfer. A.5.1 PEAK CURRENT AND PEAK TIME A combination of peak current and peak time, Figure A-6, applies a force to detach the weld droplet from the electrode and propel it across the arc.
A.5.2 FREQUENCY Frequency, Figure A-7, is the number of pulses per second or, in theory, the number of weld droplets per second. Since increasing the frequency generates more pulses in a given time period, higher frequencies generate higher average current levels.
A.6 SECOND AR Y W A VEFORM P ARAMETERS A.6.1 RAMP-UP RA TE The ramp-up rate is the speed of current climb from the background current level to the peak current level. Faster ramp-up rates tend to produce a plasma plume that quickly surrounds the end of the next droplet.
A.7 APPLICA TION EXERCISE This application exercise steps the user through the development of a basic PowerWave welding program using Wave Designer . Your application most likely will vary from this example but the concepts outlined are recommended for all development work.
Our Experiment: We found multiple droplet detachment with an arc length that was too long at these waveform settings. To attain the proper droplet detachment, we reduced the peak current value to 250 amps and found improved weld droplet transfer. But reducing the peak current also caused the arc to be shorter.
7. Click on the button to display the WorkPoint Editor window. Check only those wire feed speed points that have been developed (only 150 in/min. at this point). The WorkPoint Editor can also be used to change the wire feed speed value of a workpoint.
A-20 Appendix A PULSE W A VE SHAPING PRINCIPLES WAVE DESIGNER 8. For a second workpoint we went to 300 in/min. Select the 300 in/min. wire feed speed from the pulldown menu in Waveform Editor window. Reset the PowerFeed for 300 in/min. with a 1.00 trim.
Appendix A A-21 PULSE W A VE SHAPING PRINCIPLES WAVE DESIGNER 12. Open the “Edit” screen and select only those workpoints that have been developed (150 and 300 in/min.). Select the button to interpolate the remaining workpoints. The function gives a estimation of the values needed for the other wire feed speeds.

WELD DROPLET TRANSFER. • From time T 0 to T 1 : Background current is a steady-state current level, between 50 and (Background Current) 100 Amps that maintains an arc to form a weld bead.
B.3 STT (SURF A CE TENSION TRANSFER) The Invertec STT power source is a high-frequency, current-controlled machine that delivers power to the arc based on immediate arc requirements. The Invertec STT produces large electrode current changes within microseconds.
T 2 – T 3 The pinch mode applies an increasing, dual-slope ramp of current to the shorted electrode. The dual slope ramp of current accelerates the transfer of molten metal by the electric pinch forces. The pinch force is directly proportional to the square of the pinch current.
B.4 STT W A VE DESIGN PROCESS The Wave Designer software interfaces with the welding machine controller to permit real time communication of STT wave design changes. Refer to paragraph 2.3 for equipment interface connections. Use the wave design process to customize a standard wave shape.
B.4.1 SELECTING A ST ARTING W A VE SHAPE When customizing a waveform for a specific welding application, we recommend that you use a waveform in an existing weld file. An existing weld file can be selected from the systemWeldFiles folder in the Wave Designer directory as follows: a.
NOTE: You can edit one or more workpoints to values other than the defaults. However, the listing of wire feed speeds displayed must be the same or increasing from top to bottom. All four wire feed speeds must be assigned values, but multiple workpoints can share the same value.
2. Find the Optimal Ar c Characteristics Use the following weld trials and adjustment sequence to tune the selected waveform for your weld application at the designated workpoint (wire feed speed). Weld trials and adjustments are more easily performed with one person welding while you adjust the waveform parameters at the computer terminal.
3. Adjust the Start Control P arameters (Optional) The start control parameters can be adjusted to define how the welding machine will respond when the arc is struck. To view the start control window, click on the button on the Waveform Editor screen.
4. “Go Figure” / Make the W avef orm Synergic Weld synergy is established by shaping the 2nd and all subsequent workpoints. Being synergic, the waveform parameters automatically adjust to programmed data table values. The data table values are unique for selected wire feed speeds.
B.5 PRIMAR Y STT W A VEFORM COMPONENTS The following paragraphs describe how peak current, background current, and tailout effect weld droplet transfer. B.5.1 PEAK CURRENT The peak current control acts similar to an “arc pinch” control. Peak current serves to establish the arc length and promote good fusion.
B.5.3 T AILOUT The tailout provides additional heat without the molten droplet becoming too large. Increase tailout as needed to add heat to the arc without increasing arc length. (This will allow for faster travel speeds and improved wetting). As tailout is increased, the peal and/or background current is usually reduced.
B.6 SECOND AR Y STT W A VEFORM COMPONENTS NOTE: The Invertec STT power source circuitry automatically establishes proper values for most primary and secondary waveform components. The values can be adjusted, but should not be set far from their automatically set values.
