Pipe welding

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.
