INSTRUCTIONS

1. Given the engineering sketches and layouts, draw the re-quired number of views and proper welding symbols for each problem. Completely dimension unless otherwise specified.

2. For Problems 18.1 through 18.7, given the drawings showing actual welds or drawings and specifications, draw the necessary views and proper welding symbols. Use an appropriate ASME sheet size with border and sheet block.

3. For the remaining problems, draw the necessary views and completely dimension and place proper welding symbols. Use an appropriate ASME or architectural-style sheet size with border and sheet block based on the drawing content, unless otherwise specified by your instructor.
