Position Based Firing

“Position-based firing” is AMADA WELD TECH’s term used to describe variable speed contour laser welding.

Here’s how it works: the motion system is set up to minimize the magnitude of the sharp changes in acceleration by slowing down as needed at these inflection points and then speeding up along the benign segments of the contour.  Using special software to achieve position-based firing along the contour, it becomes a simple matter to fire the laser not at a constant repetition rate, but rather in response to its actual position along the contour at any point in time.
