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