Course Prefix & No.: LEC: LAB: Credit Hours:
WELD 1000 3 0 3
COURSE DESCRIPTION:
A good first welding course for student welders seeking degrees, certificates or diplomas. Students learn the
elements of print reading with special emphasis on interpreting welding symbols. Basic welding information
will be covered such as process fundamentals and selection considerations, weld types, joint design and welding
terminology. Students successfully completing this course will be well prepared for success in the program.
COURSE PREREQUISITE (S): None
RATIONALE:
The primary purpose for this course is to prepare the student for success in the welding program by imparting
information fundamental to the welding field. Standard terms and definitions, the principles of orthographic
projection, welding symbols, types of lines, weld positions, weld joints, weld types, and metallurgy are
examples of the topics covered in this course. This key information will be reinforced thoughout the balance of
the courses on the students’ way to degree, certificate or degree completion.
