DEGREE/DIPLOMA/CERTIFICATE COURSE DESCRIPTIONS

WELDTC – Welding Technology (Department 621) WELDTC-101 Credits:2 Welding Theory 1 This course covers the theory and application of the gas tungsten arc welding and oxyfuel welding and cutting processes. The major safety standard, ANSI Z49.1 Safety Welding and Cutting, is studied in detail. WELDTC-102 Credits:3 Welding Theory 2 This course covers theory and process control of the major consumable arc welding processes: SMAW, GMAW, FCAW and SAW. Computer based information systems are used to identify, research and write four technical papers in the lab portion of the course. WELDTC-103 Credits:3 Weld Testing This lecture/lab course de fi nes properties of welded materials and performs the tests to measure those properties. Applicable AWS procedures and codes are examined and applied to the tests. Tests performed include tensile, bends and cross sections as well as others. The course also covers evaluating failure modes to determine applicable code compliance. Prerequisite(s): Complete WELDTC-111, WELDTC-112 or WELD-315. WELDTC-105 Credits:3 Weldability of Materials This course examines the characteristics of weldable materials and their properties that affect weldability: “the capacity of a material to be welded under the imposed fabrication conditions into a speci fi c, suitably designed structure and to perform satisfactorily in the intended service” (AWS A3.0). Students gain the theoretical and technical knowledge needed to research and develop preliminary welding procedures for joining the major weldable materials. Prerequisite(s): Completion of or currently enrollment in WELDTC-102. WELDTC-107 Credits:3 Fabrication Graphics The skills needed to interpret and apply the information conveyed by conventional and computer-generated fabrication blueprints are developed. Student receives hands-on experience in operating a CAD system to generate and manipulate fabrication databases. WELDTC-111 Credits:4 Welding Practice 1 The purpose of this course is to give students hands-on experience in the setup and operation of welding with the gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW) processes. Students will complete various lab exercises demonstrating the ability to use both processes to perform welds that meet AWS D1.3 welding code for materials under 1/8-inch in thickness. Upon completion of this course, students will be able to understand a written

welding procedure, read weld symbols, properly set up welding equipment and perform welds in all positions on various light gauge materials. Prerequisite(s): Completion of or currently enrolled in WELDTC-101. WELDTC-112 Credits:4 Welding Practice 2 The purpose of this course is to give students hands-on experience in the setup and operation of shielded metal arc, gas metal arc and fl ux cored arc processes to weld the basic joints in all positions to commercial and code quality standards. Prerequisite(s): Completion of or currently enrolled in WELDTC-102. WELDTC-113 Credits:3 Welding Techniques 1 The purpose of this course is to give the theoretical and technical knowledge needed to develop, write and qualify welding procedures and welders to written speci fi cations and codes and to pass the National Certi fi edWelding Inspector’s Exam. Prerequisite(s): Complete WELDTC-101 or WELDTC-102 with a grade of C or higher, or complete WELD-350, WELD-351 and WELD-352 with a grade of C or higher. WELDTC-114 Credits:3 Welding Techniques 2 This course gives students hands-on experience in developing, writing and testing welding procedures to the major welding codes. Students also test and qualify welders to the major codes. Prerequisite(s): Completion of or currently enrolled in WELDTC-113. WELDTC-135 Credits:4 Automated Welding Processes Students gain hands-on experience with automated welding processes. This includes setup, programming, operation and troubleshooting of automated welding equipment, including industrial robots and weld fi xtures. Prerequisite(s): Completion of or currently enrolled in WELDTC-140. WELDTC-140 Credits:4 Manufacturing Applications for Robots Students gain hands-on experience with automated welding processes. This includes setup, programming, operation and troubleshooting of automated welding equipment, including industrial robots and weld fi xtures. Prerequisite(s): Complete WELDTC-111, WELDTC-112 or WELD 315 with minimum grade of C or higher and WELDTC-101, WELDTC-102 or WELD-352 with minimum grade of C of higher. WELDTC-181 Credits:1 Intro to Welding Technology This course is designed to provide students with an overview of the type of technical careers in the welding fi eld that MATC’s Welding Technology program prepares them for. Those careers include but are not limited to welding robotics programmer, inspector and trainer. These topics are covered through lecture and discussion.

WELD-351

Credits:1

Shielded Metal Arc Welding Processes Instruction is offered in the principles of shielded metal arc welding as applied to different types and thicknesses of metals in various joint con fi gurations. The principles of various testing methods for assuring weld quality are also presented, along with the proper techniques and applications of the SMAW process. Introduction to the weldability of metals is given. WELD-352 Credits:1 Gas-Shielded Arc Welding Processes The principles and theory of the semi-automatic wire welding processes as applied to different types and thicknesses of metals in various joint con fi gurations are emphasized. Various testing methods used for assuring weld quality are covered. WELD-354 Credits:2 Layout and Print Reading Practices Develops advanced skills in print reading through utilization of complex industrial prints that feature AWS welding symbols, ISO welding symbols, American Standard dimensions, SI Metric dimensions, isometric drawings, section drawings, material lists and assembly drawings. Students get hands-on experience working with prints related to the work environment for welding. Students will learn to create drawings by utilizing dividers, square, scales and protractors from existing drawings, written directions and sample mock-ups. The skills in this course transfer to the Layout and Setup course in the lab. Prerequisite(s): Complete WELD-360 or WELD-361 and WELD-362 and WELD-380. WELD-360 Credits:2 Blueprint Reading for Welders Develops fundamental skills in print reading through the use of basic lines and views, basic sketching, dimensioning techniques, title block, notes, sections and details, and types of prints. Emphasis is placed on orthographic projection and isometric views to help the learner develop the visual relationship between an object and a print in the fi rst weeks of the course. Students get hands-on experience with prints for analysis of dimensions, welding symbols, material list, parts of a print and all the conventions used in the workplace. Students will learn basic weld joints, welding symbols and knowledge of AWS standards for welding symbols. WELD-380 Credits:1 Welding Trades Mathematics Provides a focus on mathematics used in industry including fractions, decimals, percent, tolerance, various measurements, the metric system and geometry. Students apply contextual word problems while learning numeric functions. Basic mathematical processes and use of a calculator should be known prior to taking this course.
