Product Description
All position basic AC/DC electrode with 120% recovery for welding high-strength, fine-grained constructional steels (> 690 MPa) with excellent sub-zero toughness down to -50 degrees C and low diffusible hydrogen levels.
Use shortest possible arc. Weave slowly when permitted. A slight weave can be used for standing fillet welds. Use DC- (+ earth) for root runs.
“The field reports from Filarc 118 users are excellent,” Jean-Philippe Ernoult, Global Product Manager for Non- and Low-Alloyed Electrodes, ESAB. “One of our large crane manufacturer customers uses our reformulated electrode for high strength steels where overheating is not an option because it could degrade mechanical properties. The welders tell us that they can weld with Filarc 118 at lower amperage yet retain exceptional arc stability and puddle control.”
Ernoult explains that where MMA electrodes for high-strength steels typically compromise on weldability, Filarc 118 is formulated to be operator friendly. It has good arc concentration, good wetting and tie-in at the toes of the weld and a small, manageable weld puddle. “Using an electrode that provides smaller weld beads and allows for multiple passes at lower amperages minimises the risk of stress cracking,” he says.
