Unit 3: Welding Fundamentals Students will identify and use welding symbols and read detailed drawings; sketches will include basic welding symbols for fillet welds, groove welds, and other basic welds. Students will demonstrate the use of elements within a detailed drawing and interpret welding symbols from a detailed drawing. Additionally, students will be able to identify and use the basic weld types, weld joints, and weld positions. 15 Periods 675 Minutes (4) The student compares and contrasts welding joint design, material symbols, and welds. The student is expected to: (A) demonstrate knowledge of welding sketches; and (B) identify types of welds such as fillet, groove, spot, plug, and flanged Unit 4: Oxy-Fuel Cutting Students will be able to identify and explain, cutting. Students will demonstrate the safe setting up and disassembly process of oxy-fuel equipment. Students will demonstrate lighting, adjusting, and making cuts with oxy-fuel. Explain some common hazards in oxy-fuel cutting. 20 Periods 900 Minutes (7) The student performs oxy-fuel cutting processes on carbon steels. The student is expected to: (A) use safe operating practices; (B) perform safe handling of compressed gases; (C) identify components of oxy-fuel gas cutting; (D) demonstrate proper set-up procedures for the oxy-fuel process; (E) identify the factors affecting the oxy-fuel cutting of base metals; and (F) demonstrate proper cutting techniques such as piercing, straight line, and
Unit 5: Shielded Metal Arc Welding (SMAW) Students will understand that Shielded Metal Arc Welding process (SMAW), commonly referred to as stick welding, derives the heat for welding from an electric arc established between a consumable stick electrode and the part to be welded. During this unit students will demonstrate knowledge of basic shielded metal arc welding (SMAW) including setting up of equipment. Students will identify and explain the American Welding Society (AWS) classification of wire. Students will identify, explain, and demonstrate the proper AWS codes for fillet weld quality performing fillet welds in the flat, horizontal, vertical, and overhead positions to AWS code. 25 Periods 1,125 Minutes (8) The student performs shielded metal arc welding principles and practices on metals. The student is expected to: (A) use safe operating practices; (B) demonstrate knowledge of welding currents; (C) apply shielded metal arc welding principles; (D) demonstrate proper set-up procedure for shielded metal arc welding; (E) determine appropriate electrodes for base metal in shielded metal arc welding; (F) perform fillet and groove welds in all positions; and (G) prepare joints for welding Unit 6: Gas Arc Welding Students will learn and understand that Gas Metal Arc Welding (GMAW) is a process in which an electric arc forms between a consumable wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to melt and join; GMAW eliminates any need for a welding rod. Students will use appropriate equipment for safe operating practices for base metal in gas metal arc welding. 25 Periods 1,125 Minutes (9) The student performs gas metal arc welding principles and practices. The student is expected to: (A) use safe operating practices; (B) apply gas metal arc welding principles; (C) demonstrate proper set-up procedure for gas metal arc welding; (D) use appropriate equipment setup for base metal in gas metal arc welding; and (E) perform fillet and groove welds using gas metal arc welding with various metal transfer processes
