Lincoln welding electrodes for low alloys

Lincoln Electric Company, The


Lincoln Electric has added three electrodes - Excalibur 7018-A1 MR, Excalibur 8018-B2 MR and Excalibur 9018-B3 MR - to its range of low hydrogen stick electrodes.

These low-alloy consumables are ideal for process piping and pressure vessel welding applications, as well as the power generation and petrochemical industries.

The Excalibur stick (MMA) 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 per cent molybdenum steels, while the Excalibur 8018-B2 MR is suitable for 1.25 per cent chromium, 0.5 per cent molybdenum steels.

The Excalibur 9018-B3 MR is engineered specifically for welding 2.25 per cent chromium and one per cent molybdenum steels.

Excalibur electrodes offer industry-leading operability and arc performance with an exceptionally smooth arc and square coating burn-off for improved operator control and increased visibility of the weld puddle.

In addition, the 3/32in diameter electrodes' 12in 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 9001 and 14001 standards for environmental and quality management systems.
