The next wave of pipe seam submerged
arc welding
LINCOLN Electric has developed
Lincolnweld® Emergence to help
welders avoid common processing
flaws that can lead to costly repairs and
excess scrap.
Lincolnweld Emergence is a non-
copper coated submerged arc wire
with a proprietary surface treatment to
protect material and perform the same
as copper coated wires in the same
alloy class.
It also improves wire conductivity
over competitive non-copper coated
wire. The elimination of surface copper
in Emergence decreases the risk of
weld contamination. The right selection
of contact tip and wire is critical to
maintaining an optimal production
process. Emergence wire doubles
the life of contact tips, resulting in
consistent arc starts, wire placement
and weld deposit, and less downtime
and lost production due to frequent
change outs.
Emergence is part of a comprehensive
product line to support every pipe seam
application. The exact wire composition
of Lincoln Electric’s copper coated
wires makes requalification for welding
procedures controlled by classification
easy.

Enhanced coupling makeup machines
WITHIN its product ranges for oil and
gas pipe finishing lines, Lazzari has
improved the design and technical
features of its high-productivity Coupling
Makeup machines (CM), in order to meet
the latest requirements of API standards
for quality and increased performance.
All components of the CM series
machines have been redesigned and
improved to allow a fully automatic
complete cycle to apply couplings on
tubing and casing pipes up to 508mm
(20") nominal OD, up to a maximum
torque of 130,000Nm in the case of
special Premium coupling types.
The machine controls and measures
the values of torque and turns during
the whole pre-screwing and screwing
operation, recording the graphics of the
coupling final screwing with automatic
working cycle with torque priority or
position priority. The machine operator
works from a touch panel, guided by
an icon system, to manage the receipt
of pipes and machine data, as well as
machine diagnostics and alarms.
The machine mainly consists of a
robot to load the couplings directly from
the coupling container, a storage chute
for the coupling measurement and for
the dope application on the coupling
thread, starter unit, screw-on unit,
short drifter unit, pipe transfer unit by
rotating arms, a set of durable tooling,
and auxiliary hydraulic and electrical
equipment.
The equipment to be supplied
is manufactured with high quality
materials and components, ensuring
long-life performance and reliability.
Lazzari also guarantees efficient
supervision to the erection and putting
into operation at the buyer’s site, as
well as constant assistance through
online connection and availability of the
service of its technicians.
