How much do you know about welding and exhaust pipe bending?

Study Notes

There are three methods of bending exhaust pipes: program card, pattern bending, and custom bending.
Program cards provide information on pipe length, diameter, distance between bends, and rotation and depth of bends.
Pattern bending involves measuring and comparing the old pipe to make a new one.
Custom bending is necessary when there is no program card or existing pipe.
End finishing is important for connecting exhaust system components, and pipe bending machines have swaging and expanding attachments for this purpose.
Metal inert gas (MIG) welding is an arc welding process that uses a continuous solid wire electrode heated and fed into the weld pool from a welding gun.
Oxy-acetylene welding is used for welding, cutting, and heating to normalize metal, to shrink metal, to forge or shape metal, and to solder.
The welding and cutting set consists of oxygen and acetylene cylinders, regulators, hoses, welding torch, and friction lighter.
Shielding gas selection for MIG welding depends on the material being welded and the application.
The process offers high productivity, as the wire is continuously fed.
Oxygen and acetylene cylinders are used for welding and cutting metal.
Cylinders contain compressed gas at pressures up to 2,200 PSI.
Acetylene cylinders contain a porous filler material wetted with acetone.
Regulators are used to adjust high oxygen and acetylene pressures to lower working pressures.
Oxygen and acetylene regulators connect to cylinders differently to avoid mixing them up.
Double-line rubber hoses are used to connect cylinders, regulators, and torches.
Check valves and flashback arrestors are used to prevent backflow and flashbacks.
The torch consists of a handle, oxygen and acetylene gas valves, and a mixing chamber.
Flashbacks and backfires can occur with improper torch operation.
Safety precautions must be taken when using oxy-acetylene setups.
