Vacuum control system regulates
pressure in micro laser beam welding
Focus GmbH has launched a system for
micro laser beam welding in vacuum. The
Focus LaVa L95 is equipped with a vacuum
control system for precise pressure regulation. After initial pump-down, a noble gas
pressure valve regulates to the desired
welding pressure. This allows operating
the welding process from the low end of 1 mbar up to 200 mbar.
A special mode gives the option to operate the laser beam welding process
under atmospheric pressure with a shielding gas. This makes the system suitable for metallurgical R&D work.
The machine comprises a 95-l process chamber. Integrated CNC interpolates the motion of an XY table, rotary devices, and the Z move of the laser
focus in common with the laser power. Since the optics, laser, and fiber guides
are handled in atmosphere, the system can be equipped with a variety of laser

Portable welding tool fits in backpack
The Tactical Welder portable welding
tool from Ultra Tech is powered by a 528-
Wh lithium-ion battery pack and 10-amp
charger. An electronic battery management system controls charging and discharging functions. The 300-amp, indus-trial-grade welding gun has thumbwheel
wire feed speed control and an integrated triggered gas valve for GMAW and
FCAW of aluminum, steel, and stainless metals.
All components are designed to be stored, carried, and operated while
wearing the included backpack/shoulder bag. The shoulder strap allows the
pack to be worn as a tool bag with a holster for the spool gun and tools. This
allows for one-handed welding operations while wearing the pack.
According to the company, the tool can produce welds that meet AWS D1.1
structural steel requirements based on face bend and root bend tests. It can
be used in remote or confined spaces where there is no source of power, or in
work areas too small for tanks, cables, and standard-sized welding machines.
The system includes a high-current contactor for cold-tip operation.

Abrasive waterjet shapes 3-D
components in different work planes
Water Jet Sweden has introduced the FiveX waterjet
machine, built to repeatedly
perform free-form cutting of
full 3-D parts. A Z-axis capacity of at least 39 in. provides
a generous working area in
the finishing of large and
odd-size parts. An intelligent
probe interface is integrated
with a large library of predesigned 3-D measurement cycles for quick setup, and electronic abrasive feeders control and secure a continuous cutting process.
The machine is designed to counteract torsion, manage vibrations, and
handle irregularities during advanced 3-D shaping to maintain a repetition
accuracy of 0.00098 in. The machine is built on a heavy-duty steel frame with
high walls and two independent Y-axis motors to carry the cutting units and X
beam. The patented gantry design enables a smooth movement with less wear
of mechanical parts and a more consistent cutting result, the company states.
The full-size walls not only give stability to the machine frame, but also are
important safety barriers for the operator. With its automated back and front
protection, the design enables cutting in all directions.
Each machine is designed to meet the production requirements of each customer. Customized probe function and a fixturing table are common features.
When a second cutting unit is activated, the waterjet cutting machine turns into
a multiple-head cutting tool. The 2-D head features a drilling unit, height sensor, and electronic abrasive feeders to control and secure the cutting process.
