The Lincoln Electric Company Mar 29, 2006

Press Release Summary:

Gas-shielded, flux-cored AWS E71T-12 wires, UltraCore 712C and UltraCore 712A80, are used for mild steel welding. Suitable for tank and shipbuilding applications, UltraCore AWS E71T-12 wires exhibit high impact values regardless of notch location in weld joint. T-12 wires are tri-classified meeting AWS T-9 and T-1 requirements and suited to deliver impacts for low temperature or fracture critical applications. They feature ProTech(TM) packaging.

Original Press Release:

Lincoln Electric Adds Ultracore(TM) T-12 (AWS E71T-12) Gas-Shielded Flux-Cored Wires

February 2006

o Premium gas-shielded, flux-cored wire line expands with two new wires for fracture critical heavy fabrication applications

o UltraCore(TM) wires are made to tight manufacturing tolerances and deliver tremendous arc stability

o All electrodes shipped in ProTech(TM) packaging for improved quality and consistency

Cleveland, Ohio - The Lincoln Electric Company introduces two new UltraCore(TM) gas-shielded, flux-cored wires for mild steel welding in the pressure vessel, offshore and shipbuilding, bridge and heavy equipment industries. These two new AWS E71T-12 wires include economical UltraCore 712C and smooth-running UltraCore 712A80.

UltraCore(TM) 712C - For tank and shipbuilding applications using straight CO2, 712C is a versatile E71T-12 wire exhibiting consistently high impact values regardless of the notch location in the weld joint. Tensiles are capped at 90 ksi for excellent crack resistance.

UltraCore(TM) 712A80 - Lincoln's best-running E71T-12 with superior arc characteristics and high impacts in a variety of applications, such as offshore, tank and pressure-vessel fabrication. Robust impact values regardless of the notch location in the joint make this a favorite for designers who require consistently high impacts.

UltraCore premium gas-shielded wires were introduced to the market early in 2005. Each is specifically designed to deliver outstanding welding performance for use with a particular shielding gas mix, group of welding positions or industrial applications. In manufacturing, UltraCore's extremely tight tolerances on chemical composition, diameter and other parameters produce unparalleled performance consistency for reliable mechanical properties and arc action you can depend on from weld to weld.

UltraCore wires feature Lincoln's new ProTech(TM) packaging, which minimizes moisture and increases resistance to cracking and gas tracking.

AWS E71T-12 wires are tri-classified - also meeting AWS T-9 and T-1 requirements. However, T-12 wires differ in relation to tensile strength. T-12 wires are required to pass tensile strength testing in a specific range of 70-90 ksi. In many applications, a T-12 wire can be substituted for a T-9 or T-1 wire to reduce the tendency for weld cracking as well as to obtain reduced hardness. T-12 wires are generally better suited to deliver better impacts for low temperature or fracture critical applications. T-12 electrodes also meet the lower manganese level requirements of the A-1 analysis group in the ASME Boiler and Pressure Vessel Code.Previously offered to fabricators earlier this year:
UltraCore(TM) 71A75 Dual - A general-purpose wire that can be used with either straight CO2 or mixed gases. 71A75 Dual delivers a stable arc, low spatter and a smooth bead for general applications.

UltraCore(TM) 71A85 - Designed for high argon mixed gases welding in shipbuilding and structural fabrication. It is Lincoln's best-running E71T-1 for high-argon gas blends with superior arc stability and fast-freezing slag for easy out-of-position welding, even with 1/16-inch diameter wire.

UltraCore(TM) 71C - For economy welding with straight CO2 shielding gas in shipbuilding and barge applications. 71C delivers superior arc characteristics for single and multi-pass welds. It produces fast-freezing slag for easy out-of-position welding down to 1/16-inch diameter.

Scheduled for worldwide availability soon:
UltraCore(TM) 712A80-H - Designed to achieve low hydrogen levels for the toughest applications in heavy equipment, offshore and pressure-vessel fabrications. It is ideal for all-position, single or multi-pass welding on heavy sections where hydrogen-induced cracking is a concern. With 712A80-H, the need for preheating is potentially reduced.

All UltraCore wires are manufactured under a quality system certified to ISO 9001 and ISO 14001 environmental standards.

The Lincoln Electric Company, headquartered in Cleveland, Ohio, is the world leader in the design, development and manufacture of arc welding products, robotic arc-welding systems, plasma and oxyfuel cutting equipment and has a leading global position in the brazing and soldering alloys market.
