Every welding power source, component and filler metal has its unique benefits, as well as certain limitations. Metal-cored wires are no different. While certainly not a new technology, metal-cored wires have been gaining popularity in recent years, particularly in the manufacturing, fabricating and repair industries. Still, there seems to be some mystery surrounding this filler metal, with much less known about it among the general public compared to its counterparts, including solid wires. In many cases, there are some common misconceptions surrounding metal-cored wires, too.
To gain a better understanding of metal-cored wires, it helps to consider the technology behind these filler metals and the applications for which they are best suited. Additionally, it is important to know the general characteristics of metal-cored wires, along with the ways they can bring potential improvements in the welding operation.
