Terminology and Theory
The full term for OAW
What is oxyacetylene welding?
this motion helps evenly distribute heat across the weld.
What is a circular or weaving motion?
Always do this to the area before lighting the torch.
What is check for flammable materials?
this gas supports combustion and increases the flame temperature.
What is oxygen?
This tank contains the fuel gas used in oxyacetylene welding.
What is the acetylene tank?
The process in which oxygen reacts with metal to form an oxide during cutting
What is oxidation?
The torch is usually held in this hand for right-handed welders.
What is the right hand?
This should be worn to protect your eyes during welding.
What are shaded welding goggles?
A flame with equal oxygen and acetylene producing a neutral burn.
What is a neutral flame?
This component mixes oxygen and acetylene before combustion
What is the welding torch?
The approximate temperature of a neutral oxyacetylene flame in Fahrenheit.
What is 5,600°F?
This technique is used to preheat thicker metal before welding.
What is preheating?
The process of checking for leaks in hoses or regulators.

The type of flame used for welding most steels.
What is a neutral flame?
The color of the oxygen hose in a standard oxyacetylene setup.
what is green?
The purpose of using a backhand welding technique
What is better control of the weld pool and heat
This filler metal is added manually during the weld.
What is the welding rod?
This should never be done to an acetylene cylinder.
What is lay it on its side?
A flame with excess oxygen that can cause oxidation
What is an oxidizing flame?
The part of the regulator that shows how much pressure is being delivered to the torch
What is the working pressure gauge?
The chemical symbol for acetylene
What is C₂H₂?
Term for melting two pieces of base metal together without filler.
What is fusion welding?
these safety devices prevent flames from traveling back into the hoses.
What are flashback arrestors?
this flame type has a soft, feathered inner cone and is used for soldering or welding lead.
What is a carburizing (or reducing) flame?
These two tools are used to open and close the cylinders safely.
What are a cylinder key and a wrench?
