3 Credit Hours
Student Level:
This course is open to students on the college level in either the freshman or sophomore year and to area high school vocational students.
Catalog Description:
WEL 3623 - GTAW (Gas Tungsten Arc Welding/Structural) (3 hrs.)
This course is designed to help the student gain the knowledge and skill to produce welds on both ferrous and non-ferrous base metals using the gas tungsten arc welding method.
Course Classification:
Lab
Prerequisites:
None
Controlling Purpose:
Students in this class will gain an understanding of G.T.A.W. processes and become familiar with techniques used on various alloys of structural shaped metals.
Learner Outcomes:
Students in this course will prepare both ferrous and non-ferrous materials for welding with the Gas Tungsten Arc Welding Process. Students will demonstrate the use and care of equipment and are expected to demonstrate the ability to produce code quality welds with a variety of filler wires.

Attendance Policy:
Students should adhere to the attendance policy outlined by the instructor in the course syllabus.
Grading Policy:
The grading policy will be outlined by the instructor in the course syllabus.
Maximum class size:
Based on classroom occupancy.
Course Time Frame:
The U.S. Department of Education, Higher Learning Commission and the Kansas Board of Regents define credit hour and have specific regulations that the college must follow when developing, teaching and assessing the educational aspects of the college. A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally-established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out-of-class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time. The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face-to-face format.
