Appendix A | PULSE WAVE SHAPING PRINCIPLES |
A.1 APPENDIX OVERVIEW
This appendix provides a series of discussions on pulse wave shaping principles and the development of custom GMAW pulse waveforms. The contents of this appendix are arranged as follows:
Paragraph No./Title | Contents Description | |
A.2 | GMAW Pulse Overview | How the pulse waveform transfers weld droplets to the |
|
| weld surface |
A.3 | Adaptive and | How WFS and primary wave shape parameters effect |
| Mode | welding |
A.4 | Pulse Wave Design Process | Flowchart and step by step descriptions of the pulse |
|
| wave design process |
A.5 | Primary Pulse Waveform | How peak current, peak time, frequency, and |
| Components | background current effect weld droplet transfer |
A.6 | Secondary Pulse Waveform | How ramp up rate, % ramp overshoot, tailout speed, |
| Components | tailout time, stepoff amperage, and background time |
|
| effect weld droplet transfer |
A.7 | Application Exercise | Sample development of a power wave welding program |
|
