Description
The Hardface Electrode 650 4.0mm X 350mm 2kg provides unmatched protection in environments where extreme abrasion causes rapid wear. This high-performance welding rod creates a hard, dense surface that shields components from grinding, scraping, and sliding contact. It’s the perfect solution when metal loss happens due to fine particles or harsh materials.
Industries like mining, cement, sugar, and agriculture rely on this electrode to extend the life of critical equipment. Use it on parts such as mixer blades, augers, fan blades, screw conveyors, bucket lips, and hoppers. The 4.0mm diameter ensures controlled application, and the 350mm length supports long, steady welds. With a 2kg pack, you get just the right quantity for field repairs or workshop maintenance.
Thanks to its consistent arc stability and minimal spatter, the Hardface Electrode 650 makes welding easier. You can remove slag effortlessly, and the weld deposit reaches hardness levels up to 62 HRC. As a result, it performs exceptionally well in high-friction zones. While it’s not suited for impact, it greatly reduces part replacement in abrasive environments.
Use DC+ polarity for optimal fusion and penetration. On thinner carbon steels, preheating isn’t necessary. However, for thicker or high-carbon materials, light preheating and controlled cooling help prevent cracking. Apply this rod in single or multiple layers depending on the severity of wear.
We also stock a wide variety of hardfacing electrodes to suit your application, whether it involves impact, abrasion, or both.
