WEL3620 GAS WELDING PROCESSES COURSE PROCEDURE


WEL3620 GAS WELDING PROCESSES

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 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.

Course Classification:

Lecture/Lab

Prerequisites:

None

Controlling Purpose:

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.

Learner Outcomes:

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.

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: SAFETY

Outcomes: Upon completion of this unit, the student will be able to successfully pass a written test related to equipment used in this process.

  • Identify unsafe conditions and practices in oxy-fuel welding.
  • Correct unsafe conditions.

UNIT 2: EQUIPMENT SET-UP

Outcomes: Upon completion of this unit, the student will be able to successfully demonstrate the use and care of oxy-acetylene equipment.

  • Explain proper equipment set-up of oxy-acetylene equipment.
  • Test equipment for leaks and repair equipment as needed.

UNIT 3: METALLURGY REQUIREMENTS OF VARIOUS BASE METALS

Outcomes: Upon completion of this unit, the student will be able to successfully associate the filler metal requirements of various metal alloys with gas welding techniques.

  • Identify various base metals use in oxy-acetylene joining.
  • Associate the required filler metals for various metal alloys.

UNIT 4: OXY-ACETYLENE WELDING

Outcomes: Upon completion of this unit, the students will be able to successfully join metals together using mild steel filler metal.

  • Prepare mild steel coupons for joining.
  • Demonstrate the ability to join coupons in various positions and joint configurations with mild steel filler metals.

UNIT 5: BRAZING TECHNIQUES AND FILLERS

Outcomes: Upon completion of this unit, the student will be able to successfully join metals together using brass alloys for filler metal.

  • Identify alloys that can be successfully joined by brazing.
  • Explain methods required for sound brazed joints.
  • Demonstrate the ability to braze various alloys in several positions and joint configurations.

UNIT 6: SILVER SOLDER TECHNIQUES AND FILLERS

Outcomes: Upon completion of this unit, the student will be able to successfully join metals together using silver solder for filler metal.

  • Associate the alloys that can be joined using silver solder.
  • Identify filler requirements for various alloys.
  • Demonstrate ability to join alloys using silver solder fillers.

UNIT 7: DESTRUCTIVE TESTING METHODS

Outcomes: Upon completion of this unit, the student will be able to successfully.

  • Compare several destructive test methods for welds (oxy-acetylene).
  • Prepare specimens for testing with destructive methods.
  • Identify specific code requirements for oxy-acetylene weld according to AWSD1.1.

Projects Required:

Refer to Syllabus

Textbook:

Contact Bookstore for current textbook.

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.
