MATC 2025-26 Catalog

WELD – WELDTC

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 first 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.

WELD-327 Credits: 2 Specialized Semi-Automatic Wire Welding Welding skills are developed through the use of the semi-automatic solid and cored wire welding processes, such as gas metal arc, flux cored and submerged arc. Prerequisite(s): Complete WELD-326. WELD-328 Credits: 2 Flux Core Arc Welding This is a continuation of the concepts and skills in wire welding learned in WELD-327. Emphasis is on out-of-position welding on common joints. Prerequisite(s): Complete WELD-327. WELD-329 Credits: 5 Advanced Heavy Plate This course is a continuation of WELD-325 Basic Heavy Plate Processes. There is an emphasis on advanced welding techniques using 1/16th and 3/32nd electrodes with FCAW. Students will complete full penetration welds utilizing carbon arc gouging and finish grinding techniques. The training will mimic practical situations one would encounter working in the heavy plate industry today. Employment is not guaranteed to anyone upon completion. You must prove your welding skills and core abilities such as showing up every day and on time. Most employers engage in strict drug testing that can go back as far as six months. Prerequisite(s): Complete WELD-325. WELD-340 Credits: 2 Welding for Auto Body Technicians Skills for the auto body shop are stressed during instruction on the use of the oxyacetylene torch and arc and wire welding equipment to complete bead, butt, lap and fillet welds.

WELD-350

Credits: 1

GTAW Processes Safe working habits in handling oxyfuel and gas tungsten arc equipment are developed. The principles for applying oxyfuel on different types and sizes of materials in various joint configurations are stressed. Commercial production, handling and storage of compressed gases that are used in GTA and oxyfuel processes are discussed. Introduction to metallurgy is given. WELD-351 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 configurations. 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 configurations 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.
