Lincoln Electric Introduces Excalibur® 7018 XMR™ Stick Electrode
Product Advancement Extends Moisture Resistance Capabilities for Welders
Electrodes, when exposed to air, pick up moisture over time. The moisture typically increases the hydrogen content of the weld – and potentially leads to failure. Low hydrogen (or basic) electrodes are designed for applications susceptible to hydrogen cracking, a form of failure occurring when moisture causes porosity in the weld.
Excalibur 7018 XMR is used for general fabrication in many industries, including:
- Structural
- Pipeline
- Chemical Processing
- Ship Building
Previously, Lincoln Electric’s Excalibur 7018 MR stick electrode was designed to meet AWS (American Welding Society) standards (AWS A5 limit for 9 hours exposure, H4R classification) for moisture resistance, meaning it will resist moisture for a full shift, or 9 hours. After that, it is common practice to put electrodes from the opened container in a rod oven to bake the moisture out of the rod coating.
“We know that it is not always easy to keep track of time while on the job. Many real world users have longer shifts than the standard 9 hours. Sometimes, it is necessary for welders to continue welding after the 9-hour mark or an oven is not available. Our customers deserve a solution that corresponds to real world situations,” said Olivier Arnoult, Product Manager, SMAW, Lincoln Electric. “Excalibur® 7018 XMR™ stick electrode minimizes moisture control risks.”
Key features of Excalibur 7018 XMR electrode include:
- Meets AWS H4R moisture requirements during up to 24 hours of exposure
- Improved coating integrity
- Extreme bendability – The rod coating maintains integrity when bent for welding in tight spaces to a greater extent than similar competitive rods
- 60% less moisture pickup vs. competition
Lincoln Electric always recommends that users follow the guidelines set by regulations and codes and evaluate the appropriateness of the welding consumable for their particular welding application.
