WEL3644 SPECIAL ALLOY WELDING/INSPECTION
6 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:
WEL3644 - Special Alloy Welding/Inspection (6 hrs.)
Upon completion of this course a student will be able to successfully produce documentation of test specimens and compare that information to codes and standards to determine component usability. Students are expected to become proficient in the identification of various common alloys and apply precautions in selecting correct filler metals for welding. Students will be introduced to automated shape cutting and become familiar with working with images, designing shapes and dimensioning, editing cut paths and cutting parts using plasma arc cutting equipment.
Course Classification:
Lecture/Lab
Prerequisites:
None
Controlling Purpose:
This course is designed to allow students to apply their knowledge and skills in welding of special alloys such as aluminum, magnesium and titanium.
Learner Outcomes:
Students in this course will be expected to pass qualification procedures in pipe welding using the Gas Tungsten Arc Welding process. Welds made in various positions will be subject to guided bend test and x-ray examination to detect flaws.

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.
