Applications / Features
Flexible, pliable welding rod on a spool. Coating produced as a composite of crushed tungsten carbide (WC) of various shapes and sizes. The welding rod has a medium matrix and scratch hardness. Suitable for hardfacing deposits on components exposed to extreme mineral wear in service. The workpiece surface should be free of scale, rust, oil and grease.
A uniform preheating of 300°C - 350°C through to the core should be performed. In the area of the hard surfacing deposit,ngg deposit, at the start of the hardfacing deposit, the temperature at the component surface should be approximately 650°C. The gas flame should have a slight excess of acetylene during application.
Applications
