Oxyacetylene iCEV Vocab

What is acetylene?

• A colorless gas widely used as a fuel and a chemical building block

• A metal-joining process which joints two pieces of base metal by melting a metallic filler which flows across the joint and cools to form a solid bond

• A flame which burns at a low temperature and can add extra carbon to welds because the flame contains more acetylene than oxygen

• A mechanical device which allows gas to flow in only one direction

What is brazing?

• A colorless gas widely used as a fuel and a chemical building block

• A metal-joining process which joints two pieces of base metal by melting a metallic filler which flows across the joint and cools to form a solid bond

• A flame which burns at a low temperature and can add extra carbon to welds because the flame contains more acetylene than oxygen

• A mechanical device which allows gas to flow in only one direction

What is a carburizing flame?

• A colorless gas widely used as a fuel and a chemical building block

• A metal-joining process which joints two pieces of base metal by melting a metallic filler which flows across the joint and cools to form a solid bond

• A flame which burns at a low temperature and can add extra carbon to welds because the flame contains more acetylene than oxygen

• A mechanical device which allows gas to flow in only one direction

What is a check valve?

• A colorless gas widely used as a fuel and a chemical building block

• A metal-joining process which joints two pieces of base metal by melting a metallic filler which flows across the joint and cools to form a solid bond

What is a flint-style striker?

• A colorless gas widely used as a fuel and a chemical building block

• A metal-joining process which joints two pieces of base metal

• A flame which burns at a low temperature

• A piece of high carbon or alloyed steel from which sparks are struck

What is an injector torch?

• A colorless gas widely used as a fuel and a chemical building block

• a torch used for GMAW and FCAW

• also called an equal-pressure torch, simply mixes the two gasses used for oxy-fuel welding

• A mechanical device which allows gas to flow in only one direction

What is a neutral flame?

• A colorless gas widely used as a fuel and a chemical building block

• A metal-joining process which joints two pieces of base metal by melting a metallic filler which flows across the joint and cools to form a solid bond

• A flame in which the amount of oxygen is just enough for burning

• A mechanical device which allows gas to flow in only one direction

What is a non-return valve?

• A colorless gas widely used as a fuel and a chemical building block

• also called a flashback arrestor, prevents the shock waves from coming back   up the hoses and entering the cylinder

• A flame which burns at a low temperature and can add extra carbon to welds because the flame contains more acetylene than oxygen

• A mechanical device which allows gas to flow in only one direction

What is an oxidizing flame?

• A colorless gas widely used as a fuel and a chemical building block

• A metal-joining process which joints two pieces of base metal by melting a metallic filler which flows across the joint and cools to form a solid bond

• A flame produced with an excessive amount of oxygen compared to acetylene; is rarely used

• A mechanical device which allows gas to flow in only one direction

What does PSI stand for?

• A colorless gas widely used as a fuel and a chemical building block

• A metal-joining process which joints two pieces of base metal by melting a metallic filler which flows across the joint and cools to form a solid bond

• Abbreviation for pounds per square inch; is used to measure pressure

• A mechanical device which allows gas to flow in only one direction
