Application Solutions
Seam Finding, often called Joint Finding, is the process of locating the seam using one or more searches to ensure the weld bead is precisely deposited in the joint by shifting the robot program path prior to welding. Seam Tracking, also known as Joint Tracking, involves real-time tracking just ahead of where the weld is being deposited. This allows for not only robot trajectory shifts, but also adaptive control such as adjustments to voltage, wire feed, or travel speed to change weld bead formation.
Servo Robot Arc Seam Finding and Tracking
Is a software based low cost solution to allow for real time corrections to the robots weld path thru the feedback of the welding current, no additional hardware is required. Two aspects of the robots path are controlled with TAST, the Tip to Work Distance (Vertical) and the Cross Seam Position (Lateral), a sinusoidal weave must be performed while welding in order to use TAST.
Through Arc Seam Tracking
Is a software based low cost solution to allow for offsetting the complete or partial weld path. Typically Touch Sensing is done with the wire or nozzle however neither of these methods produce’s perfect result’s and more recently the industry has turned to Non-Contact Touch Sensing which uses a simple laser to measure distances.
