Manipulating the SAW Voltage and Current Waveforms to Control Welding Productivity and Quality
The submerged arc welding (SAW) process uses relatively high current values and large diameter consumable electrodes to achieve high productivity, good weld quality, and desirable bead profiles. As a result, SAW is used in a wide range of applications, especially with thick-walled components. To achieve even greater deposition rates while maintaining weld quality, it is necessary to better understand the effects of voltage and current waveform manipulation, as well as the wide range of variables that can contribute to the overall waveform shapes.
