WEL3640 BASIC WELDING PROCESSES IV
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:
WEL3640 - Basic Welding Processes IV (3 hrs.)
This course serves as an introduction to welding codes, metallurgy, and the weldability of materials. GTAW and FCAW of pipe weldments and also related advanced welding processes are introduced in this course.
Course Classification:
Lecture
Prerequisites:
None
Controlling Purpose:
The purpose of this course is to introduce students to code book requirements, and how code book requirements are based off of the weldability and metallurgy of materials. It is also used to expand student’s knowledge on advanced welding processes.
Learner Outcomes:
The student will study multiple advanced welding processes such as GTAW and FCAW of pipe, ESW, SAW, and LBW, along with applicable codes and metallurgy of materials. They should gain a sound understanding of the concepts listed above.
Upon completion of the course, the student will:
- Be able to select the correct polarity, filler metal, have knowledge to replace consumable parts, and adjust the flowrate on GTAW and FCAW machines for pipe weldments.
- Understand basic codebook requirements, and procedures.
- Identify different types of materials and determine their weldability and basic metallurgic structure.
- Become familiar with advanced welding processes such as ESW, LBW, and SAW.
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.
UNIT 1: GTAW and FCAW of Pipe
Outcomes: Upon completion of this unit, the students will be able to (list unit outcomes using action identifiers in bulleted format.)
- Explain the history of the GTAW and FCAW processes, its applications, and current requirements for pipe weldments.
- Describe how specific filler metals are manufactured for both GTAW and FCAW processes.
- Explain the applications and limitations of the GTAW and FCAW process.
- List the causes of weld contamination using GTAW and FCAW.
- Describe how to remove contamination from weldments while utilizing GTAW or FCAW.
UNIT 2: Welding Codes
Outcomes: Upon completion of this unit, the students will be able to
- Explain the purpose for having codes and standards.
- Explain what might need to be considered when selecting a code or standard for a welding job.
- Identify the three most common codes and standards used in welding.
- List the types of information that may be included in a welding procedure specification (WPS).
UNIT 3: Metallurgy and Weldability of Metals
Outcomes: Upon completion of this unit, the students will be able to
- Explain why it is important for a welder to understand metallurgy.
- Describe how thermal processes affect the original grain structure of metals.
- List the factors that may affect the weldability of a metal.
- Explain the characteristic and physical properties associated with commonly welded materials.
UNIT 4: Advanced Welding Processes
Outcomes: Upon completion of this unit, the students will be able to
- Discuss applications of SAW, ESW, and EGW for fabrication.
- Describe the submerged arc welding process, and the filler metals and fluxes used.
- Describe how ESW is performed.
- List how the laser beam is generated in LBW and describe how the laser beam produces the heat to weld.

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.
Refer to the following policies:
402.00 Academic Code of Conduct
263.00 Student Appeal of Course Grades
403.00 Student Code of Conduct
Disability Services Program:
Cowley College, in recognition of state and federal laws, will accommodate a student with a documented disability. If a student has a disability which may impact work in this class which requires accommodations, contact the Disability Services Coordinator.
