    Study Notes

    Indiana FFA Welding Career Development Event Question Bank

    • Event Focus: Welding career development
    • Question Bank: Provides a compiled list of questions for the event.
    • Content Detail: Questions cover various aspects of welding, including techniques, safety, materials, and procedures.

    Welding Techniques & Safety

    • Electrode Freezing: If the electrode freezes, immediately turn off the welding machine.

    • Arc Length: Proper arc length can be judged by the sound and appearance of the arc and weld.

    • Incorrect Electrode Movement: Moving the electrode too quickly during welding leads to issues in the weld deposit.

    • Welding Positions: This includes, but is not limited to, Flat, Vertical, Overhead, and Horizontal, as well as diagonal.

    • Welding Positions(Not Included): Diagonal is not a standard welding position.

    • Straight Polarity: Work is positive, electrode is negative.

    • Second Pass Considerations: Do not perform a weld pass if the slag from the first pass is still on the metal.

    • Tensile Strength of E-7018 electrode: 70,000 pounds psi.

    • Porosity: Gas pockets and voids in the weld metal.

    • Mild Steel Composition: Low carbon content.

    • Welding Electrode Flux: Prevents metal oxide formation.

    • Duty Cycle: Refers to the continuous operating time of the welding machine.

    • Undesirable Element in Steel: Sulfur.

    Welding Materials & Processes

    • Electrode Coating Purpose: Protects the wire core and prevents impurities in the weld.

    • E-6013 Electrode Use: Fast freeze, deep penetrating, and all-purpose.

    • T-Fillet Weld: Affected mostly by angular distortion.

    • Work Angle: The angle between the electrode and the base metal.

    Elements Added to Iron

    • Steel element: Carbon

    Additional Questions & Topics

    • Welding Positions: Vertical up, other positions.

    • Electrical Current Type: Alternating current (AC) flows in one direction then the other direction (positive-negative), while direct current (DC) flows in one direction only.

    • Arc Welding Process: Describes the continuous running time for the particular process.
