Across
- 2. Gas – Gas used to protect the weld pool from atmospheric contamination (e.g., argon, CO2).
- 4. Weld – A triangular-shaped weld used to join two surfaces at approximately a right angle.
- 7. – A depression at the end of a weld caused by the welding arc stopping.
- 8. – Material used to prevent oxidation and contamination in the weld zone.
- 9. Pool – The molten metal that forms during welding.
- 12. Weld – A weld made in a groove between two pieces of metal.
- 15. – The electrical discharge between an electrode and the workpiece that produces heat for welding.
- 16. (Tungsten Inert Gas) – A welding process using a non-consumable tungsten electrode and inert gas to protect the weld.
- 17. – The location where two or more pieces of metal are joined.
- 18. – Small droplets of molten metal expelled from the weld.
- 20. Welding – Also called SMAW (Shielded Metal Arc Welding); uses a consumable electrode coated in flux.
Down
- 1. – The depth a weld fuses into the base metal.
- 3. Zone (HAZ) – Area of base metal whose properties are altered by welding heat.
- 5. – A welding defect where the weld bead is lower than the surrounding base metal
- 6. Metal – Metal added during welding to strengthen or fill the joint.
- 10. – A conductor used to create an electric arc; can be consumable or non-consumable.
- 11. – The deposited metal left by a single welding pass.
- 13. – A welding defect where the weld metal flows onto the base metal without proper fusion.
- 14. (Metal Inert Gas) – A welding process using a continuously fed wire electrode and inert shielding gas.
- 19. Weld – A temporary weld used to hold pieces in position before final welding.
