WEL3620 BASIC WELDING PROCESSES II
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:
WEL3620 - Basic Welding Processes II (3 hrs.)
Safety precautions and the use, care, and history of GTAW and cutting equipment are stressed in this course. This course also serves as an introduction to the Gas Tungsten Arc Welding process set up and operations. The PAC process and other related cutting and gouging methods are also introduced in this course.
Course Classification:
Lecture
Prerequisites:
None
Controlling Purpose:
The purpose of this course is for students to become proficient in the set up and operations of GTAW, PAC, and A-CAG processes, and how to safely operate those processes. To become familiar with the history of different processes, and how the welding world has grown.
Core Outcomes:
The student will study safety and equipment requirements in the gas tungsten arc welding processes used in the fabrication and repair of weldments. Have a sound understanding of PAC and other related cutting processes, and how they are used in industry.
Learner Outcomes:
Upon completion of the course, the student will:
- Determine the proper PPE needed for the welding or cutting process they will be practicing, and identify safety issues, and how to correct them.
- Be able to select the correct polarity, filler metal, have knowledge to replace consumable parts, and adjust the flowrate on GTAW machines.
- Be able to determine the correct tip and air flow rate needed, to safely cut material with the PAC process. Understand different torch attachments, and how they can be used.
- Become familiar with water and laser cutting, plasma and air carbon arc gouging.
Unit Outcomes for Criterion Based Evaluation:
The following outline defines the minimum core content not including the final examination period. Instructors may add other material as time allows.

- Explain how a plasma torch creates and controls plasma.
- Identify the torch body, torch head, and power switch.
- Describe the relationship between heat input and distortion as related to the plasma cutting process.
UNIT 4: Related Cutting Processes
Outcomes: Upon completion of this unit, the students will be able to
- Describe how solid-state lasers produce energy.
- Describe how gas lasers produce energy.
- List and explain the advantages of using a laser for cutting.
- Discuss the advantages of air carbon arc cutting over oxyfuel cutting.
- Explain the differences between gouging and washing.
- Explain how the oxygen lance cutting process works.
- Explain the advantages of using the water jet cutting process.

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.
