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-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

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-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

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.
