NEW STRIP WELDING HEAD FOR
60 – 90MM STRIPS
Right from the start of the project, the
demands for this electro slag strip cladding
welding head were tough. Jointly developed
by ESAB and TECH Products Sweden AB,
the main challenges were to keep the temperature
of the welding head low and to have a
design that delivers a disturbance-free process.
The electro slag process is similar to the
SAW process but demands slightly more
technically advanced equipment.
• The welding head is equipped with an
ESAB VEC-motor.
• The current contact conductors have large
flat areas designed to shield the head
against spatter sticking to the strip and
disturbing the process. The reverse side of
the current contact area is covered by a
cooling unit that is designed for maximum
flow. This is necessary since it is exposed to
direct heat radiation. Welding with 2,300A, the
temperature of the conductors never exceeds
60°C and this low temperature helps to
reduce wear and energy losses.
• The very efficient WP20SC cooling unit, which
was developed by TECH Products, is
thermostat controlled.
• The flux supply unit is designed to enable the
operator to easily control the amount of flux
and the flux height.
• At high speed welding with ESAB OK Flux
10.14, a higher flux flow is necessary as well
as precise control of the flux height.
• Electromagnets can be mounted on each side
of the welding head for more precise control
of the weld bead width.
• If needed, an extra flux supply unit can be
mounted on the opposite side so as to allow
the head to be used for SAW process
applications as well.
• The ESAB PEH box provides full process
control and monitoring of the welding.
• The equipment is designed for LAF power sources.
• When a higher current is required, it is recommended
to connect two LAF 1250 power
sources or two LAF 1600 sources in parallel.
NEW ESAB WEB SITES GO LIVE
easier to roll out across individual subsidiary sites
across the world and operating in many different
languages.
In the last few months ESAB has launched
two completely new web sites - a new international
corporate site at www.esab.com and
a new site for ESAB in North America at www.
esabna.com. Both sites display a revised
ESAB brand global identity and have been
structured to greatly enhance usability and
faster access to required information.
Web users have also developed new requirements
from corporate websites over the last few
years. Sites can no longer exist as just an online
brochure, today’s user regards the corporate
website as their first point of reference when
investigating organisations, looking for technical
details, researching information or looking at
product offerings.
ESAB’s previous web site design was first
introduced in 2001, but since then there have
been many new demands for additional online
facilities and new information requirements. In
addition, as a global manufacturer marketing
products across more than ninety countries,
ESAB has undertaken a major review of its
global brand to improve graphic and image
consistency. This new design, with its cleaner
structure and more intuitive navigation, is not
only easier for visitors to use but also is much
ESAB’s new corporate site and the ESAB North
American site are the first two to be launched
under the new design and navigation platform.
Over time the modern and progressive look and
feel to the pages will be implemented across all
other ESAB regional and national sites. Key benefits
include:
• Improved navigation structure that enables
required information to be found and
extracted easily
• Intuitive links and design
• Access to more information and data than
previously
• Full multi-language capability. Allows users in
countries with several languages to view the
ESAB web site in their chosen native language
