Safety Guidelines
(~4 hours Classroom Component)

Introduction           Welding can be a hazardous occupation. Safety precautions must be followed to
                       minimize the hazards when cutting, welding, and fabricating. Developing the proper
                       attitudes about safety and maintaining a safe working environment are the responsibility
                       of both the employer and the employee.

Power Tools
(~5 hours Classroom Component)

Introduction           There are a variety of power tools that are commonly used in the welding industry. Each
                       of these pieces of equipment will have a specific set of safety precautions to follow. An
                       apprentice needs to be familiar with the various power tools that are common to the
                       trade and have a working knowledge of the function, safe operation and purpose of any
                       particular machine.


Specific                7.      Students will be able to demonstrate the proper and safe use of power tools.

Weld Faults
(~5 hours Classroom Component)

Introduction           The ability to recognize weld faults is an essential skill of a welding apprentice. Weld
                       faults describe a variety of welding discontinuities that affect the quality and function of
                       a weld. The production of high quality effective welds is the goal of any welder and being
                       able to identify problems with welds is the first step in developing this attention to detail.

    reread a section of text, you must first set the activity up for success:
    - Prove to students that rereading is valuable to their learning.
         You can model this while doing a Think Aloud (model your
         thinking as you interpret the text, taking time to reread a

Introduction           One of the most common and economical welding processes is shielded metal arc
                       welding, or SMAW. A welder apprentice must be familiar with the equipment and
                       theory behind the SMAW welding process in order to effectively and efficiently perform
                       the welds and troubleshoot the equipment.
