INTRODUCTION TO WELDING &
2 (1-2)
INDUSTRIAL SAFETY
Introduction will cover the welding processes used in
industries. Students will gain fundamentals of theory and
techniques pertaining to arc welding and thermal cutting
processes. Shop Orientation, Equipment set-up, electrode
types, and consumable requirements for specific welding
processes and applications. Requirements for use of industrial
welding codes to develop Welding Procedures and Welder
Qualifications are introduced. Students are also introduced to
the Occupational Safety and Health Administration (OSHA),
Mining Safety and Health Administration (MHSA), and The
American National Standards Institute (ANSI) and subsequent
regulations pertaining to welding industry and manufacturing
careers, individual and work force safety and health practices.
Prerequisite None
WLD 110
WELDING SYMBOLS & BLUEPRINT
2 (2-0)
READING
A general course in blueprint reading and welding symbols and
their application. This course will cover visualization of objects
and shapes, reading the blueprint for finding size and location
dimensions, symbols, mathematics notes and related welding
and assembly information shown on the print. This course
further develops the student9s understanding of how to read
welding blueprints and develops the range of thinking required
to assemble simple components and complex assemblies
from welding prints.
Prerequisite None
