The ilmenite welding electrode has advantages of low cost and excellent welding technological properties.However, the welding quality is affected adversely by its poor crack resistance.To solve this problem, 12 kinds of rare earths coating formulas were optimized by means of orthogonal test design and curve fitting.Then the powders containing La/Ce O2 were extruded into ilmenite welding electrode through screw-type pressing–scribbling machine.After that, a series of mechanical properties tests w...
