WEL3622 GMAW (GAS METAL ARC WELDING/STRUCTURAL) COURSE PROCEDURE


WEL3622 GMAW (GAS METAL ARC WELDING/STRUCTURAL)

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 3622 - GMAW (Gas Metal Arc Welding/Structural) (3 hrs.)

This course offers the student the knowledge and necessary skills to produce code quality welds using a variety of wire and gas combinations common to industry for fabrication purposes.

Course Classification:

Lab

Prerequisites:

None

Controlling Purpose:

Students in this class are expected to become proficient in Gas Metal Arc Welding techniques on structural shaped materials using various electrodes and shielding gases.

Learner Outcomes:

Students in this course will develop skills in the use and care of Gas Metal Arc Welding equipment. Specific methods will be followed to produce quality welds common to industry using a variety of shielding gases and filler wire electrodes.  These welds will be made in several different positions and metal transfer methods.

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.

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.
