Electrodes help for low-alloy steels.Lincoln Electric Lincoln Electric NASDAQ: LECO is a company in Cleveland, Ohio, United States that manufactures arc welding equipment. They are a worldwide leader in production of welding equipment and have subsidiary companies around the globe, including recent strong growth in China. has added three new electrodes to its line of low-hydrogen stick electrodes facilitating process piping and pressure vessel Pressure vesselA cylindrical or spherical metal container capable of withstanding pressures exerted by the material enclosed. Pressure vessels are important because many liquids and gases must be stored under high pressure. welding applications as well as the power generation and petrochemical industries. The new electrodes - Excalibur 7018-A1 MR, Excalibur 8018-B2 MR and Excalibur 9018-B3 MR - are specifically designed for all-position welding of low alloy steels and are capable of exceeding AWS AWS Amazon Web Services AWS American Welding Society AWS Advanced Warning System AWS Advanced Wireless Services AWS Automatic Weather Station AWS Alien Workshop (skateboard company) AWS Austria Wirtschaftsservice GmbH minimum strength requirements after long-term post-weld heat treatment. Excalibur 7018-A1 MR is recommended for welding 0.5 per cent molybdenum steels, while the Excalibur 8018-B2 MR is ideal for 1.25 per cent chromium and 0.5 per cent molybdenum steels. The Excalibur 9018-B3 MR is engineered specifically for welding 2.25 per cent chromium and 1 per cent molybdenum steels. "Excalibur electrodes offer industry-leading operability Operability is the ability to keep a system in a functioning and operating condition. In a computing systems environment with multiple systems this includes the ability of products, systems and business processes to work together to accomplish a common task such as finding and and arc performance with an exceptionally smooth arc and square coating burn-off for improved operator control and increased visibility of the weld puddle," the US-based company said. "In addition, the 3/32 inch dia electrodes' 12-inch length increases ease-of-use and eliminates waste on small diameter process piping applications. The Excalibur's easy strike and re-strike capabilities and effortless slag removal minimise starting porosity and grinding time, delivering optimal productivity." Each Excalibur low alloy electrode is manufactured to ISO (1) See ISO speed. (2) (International Organization for Standardization, Geneva, Switzerland, www.iso.ch) An organization that sets international standards, founded in 1946. The U.S. member body is ANSI. 9001 and 14001 standards for environmental and quality management systems. The Excalibur 7028 In another innovation Lincoln Electric announced the addition of the new Excalibur 7028 low-hydrogen stick electrode to its premium line of Excalibur mild steel stick electrodes. The Excalibur 7028 electrode offers the same superior operating characteristics of the Excalibur line with the enhanced capabilities of higher deposition rates and increased travel speeds. This electrode is designed specifically for structural fabricators working in the flat and horizontal positions. Applications for Excalibur 7028 include ships and bridge structures, storage tanks and general heavy industrial fabrication fabrication (fab´rikā´sh  n),n the construction or making of a restoration. jobs. "Smooth, even burn-off, easy re-strikes and a clean weld puddle make Excalibur 7028 the ideal choice for maximum operator appeal," the company said. "The excellent arc characteristics of Excalibur 7028 across a wide current range give welders the ability to deposit fillet fillet /fil·let/ (fil´et) 1. a loop, as of cord or tape, for making traction on the fetus. 2. in the nervous system, a long band of nerve fibers. fil·let n. 1. and lap welds without undercutting. The superior operability of Excalibur 7028 makes it easy to repeat high quality, consistent welds. Excalibur 7028 Charpy V-notch test results typically fall in the range of 60-142 ft-lbf (84-193 J) at -40AF (-40AC), which exceeds the minimum fracture toughness required for a wide range of structural welding applications. This exceeds the American Welding Society's minimum requirement of 20 ft-lbf (27 J) at 0AF (-18AC). In addition, this low-hydrogen high speed, high deposition electrode meets AWS H8 diffusible diffusible /dif·fus·ible/ (di-fuz´i-b'l) susceptible of becoming widely spread. hydrogen limit.

The company holds a leading global position in the brazing brazing, method of joining metal parts using nonferrous filler metals with high melting points such as copper, silver, and aluminum alloys. Brazing differs from soldering (see solder) by using a higher temperature; and unlike welding, the parts are not melted. and soldering alloys market.
