Skilful welding and brazing
Hamburg – With a precisely defined, periodic pulsed wire feeder, DINSE, the Hamburg-based
specialist for welding systems, demonstrates how it is possible to skilfully weld thin plates of
thermally sensitive high-alloy steels and aluminium alloys, and how it is possible to braze surfacecoated materials and alloys between different materials.
However, in order to keep process temperatures low to minimize distortion of the base materials
plate to be welded as much as possible, it is essential to reduce the short-circuit current during
material transfer. DINSE is able to achieve this through the combination of the electrical process
of droplet detachment with a highly-precise mechanical workflow: the pulsed wire feed, a variant
of the MIG/MAG robot system. Lower working temperatures mean gap tolerances are also more
easily bridged because the required "splits" produce only colder and thus tougher weld droplets.
Finishing work is easier by significantly reducing the time it takes to strip tarnish as required with
plates heated to high temperatures.
As with all DINSE welding systems, two completely decoupled drive units precisely control the
wire feed. The adjustable torque of the first motor prevents the filler wire from bending, while the
second, speed-adjusted motor provides the exact quantity of wire required, thereby achieving
maximum consistency in the wire feed regardless of torsion, bend and length of the torch set.
The DINSE process with pulsed wire feed uses as a matter of course modular elements that are
compatible with standardised DINSE components; they are, as always, light in weight to ensure
long robot life, and compact in size to cope with even difficult component geometries. For the
engineers at this specialist Hamburg-based company, however, customers’ wishes come first and
foremost, which means for instance that a choice between gas and water cooling is still available.
The company founded in Hamburg by Wilhelm Dinse in 1954 is today one of the leading companies for welding
and brazing systems in Europe. DINSE systems are used in the automotive and general vehicle industry, aircraft
construction, agricultural engineering, in the construction of machines, plants and structural steel works, as well
as in traditional shipbuilding. In addition to traditional manual welding systems, DINSE has developed automatic
and robotic welding devices for many years. Based on standard components, DINSE systematically builds different
system solutions. DINSE has users with technologically exacting demands in all areas of application, be it MIG/MAG,
TIG, PLASMA or LASER welding and brazing.
