LA-71 Key Features
1/16 (1.6)
• A low carbon, medium manganese, medium silicon wire • Pair it with Lincolnweld®
semiautomatic submerged arc welding
• A low carbon, high manganese, very high silicon wire • Can be used with Lincolnweld®
980 flux for the best flux/wire combination when
480 MPa (70 ksi) tensile strength in stress relieved conditions • A low carbon, low manganese, low silicon general purpose electrode
• Provides the lowest hardness and is best suited for use with the Lincolnweld®
700 series of active fluxes • Industry standard for submerged arc welding applications
• A low carbon, medium manganese, low silicon general purpose submerged arc electrode
• A low carbon, high manganese, medium silicon electrode designed for use with the Lincolnweld®
• Capable of producing impact properties exceeding 27 J (20 ft•lbf) at -62°C (-80°F) when used with Lincolnweld®
800 series of neutral fluxes 888™
• A low carbon, medium manganese, medium silicon electrode containing approximately 0.1% titanium
• Small addition of titanium allows deposits to be stress-relieved with little loss of strength, even with extended stress relief times

1/16 (1.6)
• A low carbon, medium manganese, low silicon, 1/2% molybdenum wire used for single or multiple pass welds
• A standard choice for pipe fabrication and other limited pass applications
• A low carbon, medium manganese, high silicon, nickel-bearing electrode designed for use with Lincolnweld®
neutral fluxes • Suitable for use in applications requiring less than 1% Ni wire composition
• A low carbon, medium manganese, low silicon, 1/2% molybdenum wire containing small additions of titanium and boron for improved fracture toughness
• Generally used in two pass applications for arctic grade line pipe • Designed especially for high strength applications
• Recommended when over 620 MPa (90 ksi) tensile strength is required in the as-welded condition or when low temperature impact toughness is required in the stress-relieved condition
• A nickel-bearing electrode with 1/2% molybdenum
• Can be used for higher strength weldments where impact properties exceeding 27 J (20 ft•lbf) at -62°C (-80°F) are required
• A nickel-bearing wire with 0.2% molybdenum designed for use on weathering steels
• Capable of exceeding low temperature Charpy V-Notch requirements and 480-550 MPa (70-80 ksi) tensile strength in the as-welded and stress-relieved conditions

Lincolnweld® (AWS EM2)
LA-100
• A low carbon, high manganese, high silicon, 1/2% molybdenum special purpose wire
• Recommended for seam welding of pipe and for the general welding of high strength plate
• Designed for welding 1-1/4% chromium, 1/2% molybdenum steels in high temperature service applications such as pressure vessels or piping
• The AWS R designator denotes ultra low residuals which will result in a low Bruscato factor (X-factor)
• Designed for high temperature applications such as pressure vessels and piping for 2-1/4% chromium, 1% molybdenum steels
• The AWS R designator denotes ultra low residuals which will result in a low Bruscato factor (X-factor)
• A low carbon, high manganese wire with nickel and molybdenum designed to weld high strength steels such as HY-80 and HSLA-80
• Delivers yield strength greater than 690 MPa (100 ksi) • Low H2 hydrogen levels can be achieved when used with MIL800-H flux
