Abstract
Various embodiments of a metal cored wires and methods are disclosed. In one embodiment of the present invention, a metal cored wire comprises a metal sheath and a metal-powder core material comprising manganese particles. The manganese particles are coated with a coating material to reduce the manganese fumes and exposure during welding.
Claims20
A metal cored welding wire comprising:
- a metal sheath;
- a metal-powder core material comprising manganese particles;
- and
- wherein the manganese particles are coated with a coating material,
- and the coating on the manganese particles comprises a material that undergoes reduction in the presence of oxygen.
2 more elements
