Welding

Manz has developed sophisticated welding processes that produce unsurpassed seam quality with minimal use of energy. Possible applications range from spot welding of supporting structures in electronic devices, such as smartphones, to high-precision micro or macro welding of battery arrester contacts.

Welding

In addition to conventional laser welding, Manz also offers a welding process that almost completely stops the molten metal from mixing, resulting in very high-strength weld seams. Laser welding in the overlap using high-frequency local modulation, or “wobbling”.

Using wobbling the depth and width of weld seams are configured in the micrometer range independently of each other. Our automatic calibration method for a two-axis scanner system allows a wobble frequency up to 4 kHz in continuous operation with constant welding depth to micrometer accuracy while simultaneously reducing material inclusions.
