Coil joiner incorporates laser cutting, welding in single head

Joining Technologies Inc. has added new features and functions to its Infinite Web® all-in-one coil joiner. The noncontact splicing process incorporates laser cutting and welding with a single head.

These features enable the splicing of titanium coils, as well as splicing on a 15-degree bias as an alternative to forming perpendicular joints. The bias increases the splice's effective strength by increasing material at the weld joint, the manufacturer states.

The mobile, stand-alone system, which requires only an electrical input and minimal operator involvement, can service multiple converting lines. The industrial PC-based control system features a touchscreen interface, predefined programs for selected alloys, and proprietary self-diagnostics.

Able to handle material thicknesses from 0.002 to 0.040 in., the coil joiner uses coaxial optics to verify proper positioning and provide accurate splices. Both cutting and welding operations are automatic and noncontact.
