Class Notes: Welding Class 1
OK - Yesterday’s class was just an intro on how to setup equipment and how not to catch your self on fire. In fact, it seems there are dozens of ways to creatively maim yourself in the welding shop. Luckily, the safety record is excellent. What I learned;
–Mass Art doesn’t use acetylene as fuel because it is too dangerous. Propylene is much safer, although lower in flame temperature
–Acetylene spontaneously detonates at 15 psi, exploding whatever vessel it is in, killing several welders in the early days. This caused welding shops to change the threads so the oxygen and fuel systems couldn’t be cross-connected.
–An oxygen bottle is under high pressure (2500 psi) and becomes a ballistic missle if you knock it over and the valve stem shears off. Since the bottle is 5 feet tall and solid cast steel, it tends to sail right thru walls.
–Wear only cotton clothes so they don’t ignite. If you do catch fire, try to pat it out, then use the shower and then use a fire extinguisher as a last resort.
So now to come up with a design for a sculpture that I’ll be trying to make for the next couple months. Hmmmm….
