1. Types and characteristics of flux cored hardfacing welding wireAccording to the structure of the wire, flux cored hardfacing welding wire can be divided into two types of seamed wire and seamless wire. Seamless wire can be coated with copper. Seamless wire with good performance and low cost has b…
In our previous post we discussed categorizing cracks based on when they occur. Cracks can and should be categorized based on three criteria: 1.
