Design Step 6: Evaluate/Manufacture a Final Product
Read the Fine Print
Educational Use
Rating
0.0 stars

As students learn more about the manufacturing process, they use the final prototypes created in the previous activity to evaluate, design and manufacture final products. Teams work with more advanced materials and tools, such as plywood, Plexiglas, metals, epoxies, welding materials and machining tools. (Note: Conduct this activity in the context of a design project that students are working on; this activity is Step 6 in a series of six that guide students through the engineering design loop.)

Welding can be a dangerous, life threatening, and dirty job, or a safe, rewarding, and well paying career. Whether one is learning to walk, ride a bicycle, play hockey, football, or just about any other activity you can think of, safety should be your first consideration, regardless of the task that one chooses to challenge. Unfortunately a lot of us humans tend to treat safety the way we treat the instruction manual that came with the new TV. We simply choose to ignore its existence until something goes wrong. The following tips represent some of the many safety recommendations that could save lives, including yours

Oxy-Fuel Welding
Gas cylinders require special care in oxy-fuel welding. The acetylene cylinder is hollow and contains a porous material saturated with liquid acetone, which keeps the gases stable under pressure. For this reason, always store the cylinder in the vertical upright position and secure it. If the cylinder is tipped, acetone may leak into the valve area and could release acetone into the system. If an acetylene cylinder is tipped, place it upright for twice as long as it had been lying down before using it. Also, be certain a cap covers the valve when the cylinders are not secured. If the cap is not present and the cylinder falls, the valve could break and propel the cylinder, causing injury to you or other worker
