In the right welding operation, metal-cored wire can provide process improvements and simplify training, particularly if you have less-skilled welders.
Metal-cored welding wire is a composite tubular wire that consists of a metal sheath with a core of metallic powders and alloys. In many situations, this wire can increase your welding efficiencies and reduce overall costs compared to solid wires.
When should metal-cored wire be used?
Metal-cored wire is especially effective when used in heavy equipment, automotive, and general manufacturing applications, and is a good alternative to solid wire when welding 3- to 6-mm thick mild steel.
It can also help if you are experiencing challenges in your welding operation, such as:
- Poor fit-up, gaps or burn-through issues
- Inadequate side wall fusion
- High levels of scrap or rework
- Excessive time and money for pre- and post-weld cleaning
- Slow new welder training
To decide if metal-cored wire is right for you, it’s important to understand how the technology works and the key benefits it can provide.
