Welding Electrodes General Characteristics TWP 1968 is a jet type electrode for joining and build up of various alloy steels. This electrode yields a tough, crack resistant weld deposit with excellent mechanical properties. It is very economical in use due to its high efficiency with a metal recovery of approximately 150%. Applications TWP 1968 is particulary suitable for joining austenitic manganese steel to itself and carbon steel. Also recommended for build up of machinery parts subject to sliding wear and high impact loads, such as heavy construction equipment and as a cushion layer for hard overlays. Welding Procedure Clean weld area free from oil, grease, rust and other surface contaminants. Bevel heavy section before welding. Maintain a short arc and use stringer beads to prevent overheating. A weave technique may be employed when applying cushion layers prior to hardfacing. Allow deposit to cool before removing slag. Preheating and postweld heat treatment is generally not required, but may be specified or recommended for some base material.
