Welding Technology

Through classroom and/or shop/lab learning and assessment activities, students in this course will: explain gas metal arc welding process (GMAW) and; demonstrate the safe and correct set up of the GMAW workstation.; correlate GMAW electrode classifications with base metals and joint dimension criteria; demonstrate proper electrode selection and use based on metal types and thicknesses; build pads of weld beads with selected electrodes in the flat position; build pads of weld beads with selected electrodes in the horizontal position; produce basic GMAW welds on selected weld joints; and conduct visual inspection of GMAW welds

Through classroom and/or lab/shop learning and assessment activities, students in this course will: explain the gas tungsten arc welding process (GTAW); demonstrate the safe and correct set up of the GTAW workstation; relate GTAW electrode and filler metal classifications with base metals and joint criteria; build proper electrode and filler metal selection and use based on metal types and thicknesses; build pads of weld beads with selected electrodes and filler material in the flat position; build pads of weld beads with selected electrodes and filler material in the horizontal position; perform basic GTAW welds on selected weld joints; and perform visual inspection of GTAW welds.

Through classroom and/or lab/shop learning and assessment activities, students in this course will: describe the Shielded Metal Arc Welding process (SMAW); demonstrate the safe and correct set up of the SMAW workstation; associate SMAW electrode classifications with base metals and joint criteria; demonstrate proper electrode selection and use based on metal types and thicknesses; build pads of weld beads with selected electrodes in the flat position; build pads of weld beads with selected electrodes in the horizontal position; perform basic SMAW welds on selected weld joints; and perform visual inspection of welds.

Layout /Fit up Practices. The student must possess the perquisite drawing and welding symbol interpretation skill of and entry level welder. The student demonstrates a fundamental knowledge of layout and fit up principles. Shows the ability to operate shop equipment safely and use layout tools for geometric construction. Has a fundamental understanding of advanced measurement practices, design for welding and the use of fixture and positioned. Works from drawings or sketches to prepare, form or cut multiple parts and assemble simple weldments. Recognizes welded joint and welding requirements based on welding symbol information. Level II occupational orientation for Welders wishing to pursue a career in Welding need follow; safe practices, perform housekeeping duties, and follow verbal, written work instructions for the completion of detail assignments. For each unit of credit, a minimum of three hours per week with one of the hours for class and two hours for studying/preparation outside of class is expected. Pre-requisite: none
