Students completing the proposed Gas Metal Arc Welding certificate will demonstrate production methods and techniques in gas metal arc welding including spray transfer, short arc transfer and cored wires. Machine set-up, gun handling, weld size, gun angle, wire feed and gas quantities will be learned with an emphasis on safety. Experience will be gained in the flat, horizontal, and vertical positions using various joint designs, fillet sizes, and material thickness. Students will weld with consumable wire electrodes and learn three methods of metal transfer. Students will learn how to properly set up a machine and weld in various positions with ferrous and non-ferrous material and how to regulate oxygen and acetylene for the oxyacetylene welding process. Students will also use math to read welding blueprints, and interpret welding symbols, gauges, and inspection techniques.

Courses for this program include: »

WLD 109 Blueprint Reading for Welders
2 cr. hrs.; 1 lecture hour; 2 lab hours per week.
Prerequisite: Shop math equivalency/high school drafting.
Reading welding prints using mathematics, interpreting welding symbols, gauges and inspection techniques.

WLD 110 Welding Testing and Preparation
1 cr. hrs.;
1 lecture hours; 0 lab hours per week.
This course prepares students for industry weld testing. Students review how to prepare coupons, select rod sizes, gases, and amperage; learn how to manage test anxiety by understanding mental preparation; create an ordered punch list; identify potential testing pitfalls; and visually identify needed weld corrections prior to test completion.

WLD 120 Introduction to GMAW
.5-1 cr. hr.;
0 lecture hours; 2 lab hours per week.
Prerequisite: WLD 118 “C” or better.
Course designed to cover production methods and techniques in gas metal arc welding (MIG). This process will include spray transfer, short arc transfer and cored wires. This will be done by studying machine set-up, handling the gun, weld size, gun angle, wire feed and gas quantities. Safety will be emphasized.

WLD 121 GMAW Spray Arc Process
.5-3 cr. hrs.;
0 lecture hours; 6 lab hours per week.
Prerequisite: WLD 120 “C” or better.
Course provides theory and welding experience in the flat, horizontal and vertical positions using various joint designs. Various fillet sizes and material thickness will be the welding lab experiences. Shop safety will be emphasized.

WLD 122 GMAW Short Circuit and Spray Arc
.5-2 cr. hrs.;
0 lecture hours; 4 lab hours per week.
Prerequisite: WLD 121 “C” or better.
Student will learn when welding with consumable wire electrodes that transfer of metal is achieved by three methods. The type of metal transfer that occurs will depend on electrode wire size, shielding gas, arc voltage, and welding current. Various lab exercises employ different processes with different joint types and various welding positions. Shop safety will be emphasized.

WLD 125 GTAW
.5-3 cr. hrs.;
1 lecture hour; 4 lab hours per week.
Prerequisite: WLD 122 “C” or better.
The course will introduce gas tungsten-arc welding (GTAW or TIG). Students will learn how to properly set up machine and weld in various positions with ferrous and non-ferrous material. The student will learn how to regulate oxygen and acetylene for the oxyacetylene welding process. Student will weld various material thickness in different positions and pass a weld joint test. Shop safety will be emphasized.

WLD 210 Professional Seminar
1 cr. hrs.;
1 lecture hour; 0 lab hours per week.
Prerequisite: Permission of instructor.

Discussion of workplace issues, development of job-seeking strategies, and enhancement of interpersonal skills.


Gainful Employment

Gainful employment is one important measure that students and parents should pay attention to as they examine colleges and programs. All non-degree programs must be designed to lead to gainful employment in a recognized occupation in order to be deemed eligible for federal student aid. These programs are generally less than 2 years in length and result in a certificate.
