Ultrasonics' new Single Point Ground Welder SPG 2600 is for use in
manufacturing single point ground terminals. The tooling is designed for
gathering as many as 18 wires into a single terminal. Once the weld has been
made, a set of clamps automatically completes the assembly by folding over the terminal's
arms to provide stress relief on the joint.
The unit can handle wire bundles of up to 20 square mm.
The unit's power supply features a built-in microprocessor
that can store and recall up to 250 weld protocols from memory. A digital
display allows selection of welding modes by time or energy and provides
automatic frequency control and overload protection. The Single Point Ground
Welder has an RS232 port for transferring weld data to or from a computer and
utilizes automatic control monitoring that can detect when variables exceed
preset power and time limits.
The unit features heat-treated, tool steel Taper Lock Tips
that can last up to 100,000 welds and are designed for fast removal and
replacement. Ultrasonic metal welding creates solid-state metallurgical bonds
without heat, current, fluxes or fillers and there are no costs for consumables
or post-assembly cleaning.
The Single Point Ground Welder SPG 2600 uses Sonobond's
Wedge-Reed coupling system to combine high vibratory force with low amplitude
coupling. High-frequency ultrasonic energy is directed to the surface between
the metals to be welded. This is done via the unit's welding tip. The applied
vibratory energy disperses the oxides and surface films between the work
pieces. A metallurgical bond is accomplished in one step without arcs, sparks
or fumes and without melting the materials.
It can handle lightly tinned or oxidized wires.
If a major catastrophe strikes your area, will you be prepared? Do you know how to modify the tech you've already got or MacGyver what you need to fit your own situation? A free, five-day Continuing Education Center course starting April 6 will show you how.
NanoSteel Co., which develops high-performance steel alloys, began producing steel powders for additive manufacturing (AM) last year and now supplies them commercially for freeform laser deposition and laser powder bed fusion processes.
