Across
- 1. When using a 6010-6011 electrode, what technique is used?
- 4. Caused by dirty unprepped metal, insufficient gas coverage, traveling too fast and exposes the weld puddle to the atmosphere.
- 5. Not only look unprofessional, they can create weak points causing a weldment to fail under stress.
- 7. The distance from the tip of the electrode core wire to the weld puddle.
- 10. The localized area of molten metal created during welding where the base metal and filler metal mix before solidifying.
- 13. The rate at which the electrode moves along the work piece.
- 14. When using a 7018 electrode what travel angel is used?
- 16. A weld shall be acceptable by visual inspection if is shows that there is complete (blank) between the weld metal and base metal.
- 17. Exist when the electrode points in the direction of travel.
Down
- 2. Is based on the thickness of the base metal, the welding position, and the type of joint to be welded.
- 3. Ensures that welds meet code, standard, or project requirements and provides guidance for welders to produce repeatable, acceptable welds.
- 6. A weld bead profile in which the deposited weld metal rises above the plane of the base metal, creating an outwardly curved surface.
- 8. Exist when the electrode points away from the direction of travel.
- 9. Is measured in amperes or amps.
- 11. A groove or depression along the weld toe caused by melting the base metal without filling it. It weakens the weld and is usually due to excessive heat or fast travel speed.
- 12. When weld metal doesn’t fill the joint completely, leaving a concave surface and weakening the weld.
- 15. A weld bead profile that dips below the level of the base metal.
