Down
- 1. is the melting, flowing together, and freezing of metals under controlled conditions
- 3. current When electrical current alternates or reverses the direction of
- 4. through a circuit and is an indication of the heat being produced
- 6. is the direction in which the current is flowing
- 7. is the flow of tiny particles called electrons through a conductor
- 8. is running a bead with a sideways or oscillating motion
- 12. is a person who welds or a welding machine.
- 13. is the process of building up several layers of weld deposit by running overlapping passes.
- 15. is a bare metal rod that is usually coated with chemical compounds called flux
