Lincoln Electric adds three new electrodes to Excalibur line

Lincoln Electric has added three new electrodes – Excalibur 7018-A1 MR, Excalibur 8018-B2 MR and Excalibur 9018-B3 MR – to its line of low hydrogen stick electrodes. These low alloy consumables are designed for process piping and pressure vessel welding applications, as well as the power generation and petrochemical industries. The new Excalibur stick electrodes are specifically designed for all-position welding of low alloy steels and are capable of exceeding AWS minimum strength requirements after long-term, post-weld heat treatment. Excalibur 7018-A1 MR is recommended for welding 0.5 percent molybdenum steels, while the Excalibur 8018-B2 MR is ideal for 1.25 percent chromium, 0.5 percent molybdenum steels. The Excalibur 9018-B3 MR is engineered specifically for welding 2.25 percent chromium and 1 percent molybdenum steels.
