AMADA WELD TECH, Inc., a leading manufacturer of equipment and systems for welding, marking, cutting, sealing, and bonding, announces a range of galvo scan heads for precision laser welding applications.
Common usages for these scanning heads include point-to-point positioning for multi-point welding, shape welding for hermetic seams, and beam weaving to increase weld width.
- Point-to-point positioning is frequently employed where multiple welds are needed over a small area, for example, electronic connector leads. The jump speed is nearly instantaneous compared to either traditional motion stages or robotic motion, and can dramatically decrease cycle times.
- Contour welding: galvo scanning heads are adept at steering the laser beam in an XY plane to create a seam weld of any programmed shape. This is commonly used for electronic package welding, where a specific motion is necessary to create a hermetic seal, and for lap welding configurations where additional weld contact is required.
- Wobble is an extension of the seam welding application, in which the scanning head “wobbles” the beam in a small area to increase the melt pool. This improves the manufacturability of parts with lower tolerances on fit-up between the parts.
The galvo scan heads all feature advanced, intuitive software dedicated to welding, and a configurable pattern to adjust for part geometry and enhance weld performance. An integrated safety shutter ensures a safe work environment for operators.
The robust solutions are designed to work with lasers up to 3 kilowatts (kW) and field sizes up to 100 x 100 millimeters. Integrate with a linear stage motion to weld at different workpiece heights or add a wobble to linear motion for the accommodation of tolerances in fit-up for seam welds.
