Across
- 1. a bare metal rod that is usually coated with chemical compounds called flux
- 3. the percentage of a 10-minute period in which a welder can operate at a given current setting, also another way to classify welders
- 6. welding in which fusion is produced by heating with an arc between a consumable stick electrode and the work piece
- 11. something that allows the flow of electrons
- 13. negatively charged particles
- 14. the distance from the tip of the bare end of the electrode to the base metal
- 16. a person who welds or a welding machine
- 17. running the bead with a sideways or oscillating motion
- 19. the melting, flowing together, and freezing of metals under controlled conditions
- 20. a weld made in a groove between the two pieces to be joined
- 21. a measure of electrical pressure
- 22. the process of building up several layers of weld deposit by running overlapping passes
- 23. a molten metal pool
Down
- 2. electron flow in one direction
- 4. a measure of electrical current flowing through a circuit and is an indication of the heat being produced
- 5. the bottom of the weld groove opposite of the weld face
- 7. beads deposited on a metal surface for the purpose of building up the base metal
- 8. process that uses electricity to heat and melt the metal
- 9. is the opposition to the flow of current in a circuit
- 10. the direction in which the current is flowing
- 12. 2 surfaces at right angles, triangular shaped bead
- 15. electrical current alternates or reverses the direction of electron flow
- 18. the flow electrons through a conductor
