WEL3620 GAS WELDING PROCESSES
3 Credit Hours
This course is open to students on the college level in either the freshman or sophomore year and to area high school vocational students.
WEL 3620 - Gas Welding Processes (3 hrs.)
This course is designed to introduce students to oxy-fuel soldering, brazing and welding techniques used to manufacture and repair weldments. Safety precautions and the use and care of equipment are stressed in this course. This course also serves as an introduction to the Gas Tungsten Arc Welding method because of its similarities.
Students in Gas Welding Processes should become proficient in use of oxy-acetylene cutting equipment for material preparation. Oxy-acetylene equipment will be used for various weldments with several fillers including silver solder, brass or brazing, and mild steel filler wires.
The student will study safety and equipment requirements in the gas welding processes used in the fabrication and repair of weldments and machinery. Students will also study and perform the requirements for making various weldments using alloys necessary in gas welding. This course is a sound introduction into the Gas Tungsten Arc Welding Process.

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.
