Robotic welding gun features
centralized motor, magnetic drive
Nimak GmbH has developed a new concept
for robot welding guns, designed for use in
multimaterial mixes and in large-scale production using conventional steel.
The powerGUN robotic welding gun has a
centralized motor and gear unit that enables
a significant weight reduction and lower interference contours while providing superior joining results, says the company. It employs the magneticDRIVE
drive type, which uses microprocessor-controlled electromagnets. This drive
can be used in all resistance welding applications, from stationary spot and
projection welding machines to robot welding guns.
With the ultrafast power-generation and slip system, the user can set an exact power profile that controls the rise and fall of the electrode force across a
large range in milliseconds. This short, controlled welding process is suitable
for spot and projection welding of aluminum with highly varied alloys that are
used in auto and aerospace applications.

Fiber laser welding system
joins dissimilar materials, thicknesses
Automation Alternatives has introduced the RubyLaser fiber laser welding system. With its spot size as small
as 0.001 to 0.002 in. and fast weld
speeds, the system delivers high power density while minimizing the HAZ,
the company reports. The machine is
suitable for welding dissimilar materials, welding very thin materials, and joining thin and thick parts.
The laser welding system handles rapid prototyping from microwelding to
high-strength welds. Typical materials include stainless steel, titanium, aluminum, INCONEL®, HASTELLOY®, nitinol, and Kovar®.
The laser power controller can modulate the laser over a very wide range,
which helps ensure that su;iciently high laser energy is applied to melt and
join very di;erent thicknesses of material without overheating or damaging
the thinner part during the welding process.
