Introduces reading and creating basic technical drawings. Explores fabricating from drawings to industry specification and tolerances, creating and drawing parts in computer software, and integrating with CNC part generation and computer aided blueprint design. Prerequisite: WLD 195. Audit available.
Upon successful completion of this course, students will be able to:
- Identify basic and intermediate blueprint annotation and markings.
- Produce to tolerance welding samples from blueprints.
- Create welding blueprints and drawings using computer aided design programs, such as SolidEdge 2D.
- Understand programs and code used to create and produce parts in computer numerically controlled machine processes.
- Produce parts designs from computer aided design (CAD) programs and utilize CAD designs to create sample parts.
Outcome Assessment Strategies
Written assessment requiring students to identify commonly used blueprint symbols, interpreting those symbols on drawings and understanding those symbols meanings. Generated blueprints to be assessed based upon completeness and accuracy of measurement and annotation. Produced parts from code (using CAD) will be assessed for accuracy of programming/code and accuracy of part produced. Welded samples assessed to tolerance and accuracy from provided blueprints/drawings.
Course Activities and Design
The determination of teaching strategies used in the delivery of outcomes is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: lecture, small group/forum discussion, flipped classroom, dyads, oral presentation, role play, simulation scenarios, group projects, service learning projects, hands-on lab, peer review/workshops, cooperative learning (jigsaw, fishbowl), inquiry based instruction, differentiated instruction (learning centers), graphic organizers, etc.
Course Content (Themes, Concepts, Issues and Skills)
- Learn basic welding symbols through studying sample blueprints
- Memorize and understand the importance of welding specific blueprint annotations
- Understand measurements and dimensions taken from blueprints
- Weld sample projects from blueprints using appropriate weld type, process, contour and position.
- Weld sample projects and parts to correct tolerances from blueprints; accounting for warp
- Produce quality welds with appropriate in SMAW and GMAW processes in 1, 2 and 3 G and F positions
- Learn SolidEdge 2D CAD functions in order to produce blueprints and proper welding annotations.
- Learn Solid Edge 2D CAD functions in order to produce part drawings for cutting with the CNC plasma cutter
- Understand and use Sheet Cam to produce g-code for cutting parts from drawings
- Run and understand Mach3 Loader to cut parts using the CNC plasma cutter
- Understand basic g-code functions to recover parts from failed operations
- Ensure that parts created match physical specification, not just drawn specification using principles of distortion.
Safety glasses are required at all times in the welding lab, and are provided for students. Students may also purchase their own safety glasses from a local supplier. Long pants and closed toed shoes are required in the welding lab at all times. Appropriate clothing must be worn to work in the lab (no synthetic materials, etc.). Safety requirements are covered prior to work in the lab.
