An alternating current (AC) welding waveform, with two or more polarity changes during each molten metal droplet transfer cycle, is produced. The consumable welding electrode speed is mechanically controlled and the polarity is linked to known information about the electrode speed/direction, ensuring that at least two polarity changes are achieved per droplet transfer cycle. The arc polarity is concurrent with the change in direction of the electrode motion. The polarity can be changed based upon an actual speed of the electrode. Controlling the electrode motion and polarity in this way allows larger droplets to be created and higher deposition rates to be achieved at a lower frequency of shorting. The lower frequency of shorting also reduces wire feeder motor heating and wear, and increases contact tip life.

A secondary material, being of a different material from that of the welding contact tip, is positioned at or near a distal end of the welding contact tip. During the automatic GMAW welding process, detection of a flaring event of the arc by the welding system is facilitated by the secondary material changing phase in response to the flaring event, resulting in changing at least one detectable characteristic of the arc.

An embodiment includes a method of determining a collision-free space for a robotic welding system. The method includes fixing a location of a part to be welded in a 3D coordinate space of a robotic welding system. An arm of the robotic welding system is moved around the part within the 3D coordinate space. Data corresponding to positions and orientations of the arm in the 3D coordinate space are recorded as the arm is moved within the 3D coordinate space around the part. The data is translated to swept volumes of data within the 3D coordinate space. The swept volumes of data are merged to generate 3D geometry data representing a continuous collision-free space within the 3D coordinate space.
