Methods:

  • Read the Arc Welding units in the text book(s) you are using.

  • Be familiar with all handouts that you plan to use as support materials for this unit.

  • Be sure you are comfortable performing any of the skills you will be demonstrating to your class.

Standards:

B1.0 Students understand personal and group safety:
B1.1    Practice the rules for personal and group safety while working in an agricultural mechanics environment.
B1.2    Know the relationship between accepted shop management procedures and a safe working environment.
B5.0 Students understand agricultural cold metal processes:
B5.1    Know how to identify common metals, sizes, and shapes.
B5.3    Know layout skills.
B5.4    Know basic cold metal processes (e.g., shearing, cutting, drilling, threading, bending.).
B8.0 Students understand electric arc welding processes:
B8.1    Know how to select, properly adjust, safely employ, and maintain appropriate welding equipment (e.g., gas metal arc welding, shielded metal arc welding, gas tungsten arc welding).
B8.2    Apply gas metal arc welding, shielded metal arc welding, or flux core arc welding processes to fusion-weld mild steel with appropriate welding electrodes and related equipment.
B8.3    Weld a variety of joints in various positions.
B8.4    Know how to read welding symbols and plans, select electrodes, fit-up joints, and control heat and distortion.
4.0 Technology
Students know how to use contemporary and emerging technological resources in diverse and changing personal, community, and workplace environments:
4.1       Understand past, present, and future technological advances as they relate to a chosen pathway.
4.6       Differentiate among, select, and apply appropriate tools and technology.
5.0 Problem Solving and Critical Thinking
Students understand how to create alternative solutions by using critical and creative thinking skills, such as logical reasoning, analytical thinking, and problem-solving techniques:
5.1       Apply appropriate problem-solving strategies and critical thinking skills to work-related issues and tasks.
5.3       Use critical thinking skills to make informed decisions and solve problems.
