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.
