2. MAPP gas - Wikipedia

   en.wikipedia.org/wiki/MAPP_gas

   A set of MAPP and oxygen cylinders is used for oxy-fuel welding and cutting. MAPP gas was a trademarked name, belonging to The Linde Group, a division of the former global chemical giant Union Carbide, for a fuel gas based on a stabilized mixture of methylacetylene (propyne), propadiene and propane. The name comes from the original chemical ...

3. Oxy-fuel welding and cutting - Wikipedia

   en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

   MAPP gas can be used at much higher pressures than acetylene, sometimes up to 40 or 50 psi in high-volume oxy-fuel cutting torches which can cut up to 12-inch-thick (300 mm) steel. Other welding gases that develop comparable temperatures need special procedures for safe shipping and handling.

4. Methylacetylene-propadiene gas - Wikipedia

   en.wikipedia.org/wiki/Methylacetylene-propadiene_gas

   Methylacetylene-propadiene (MPS) gas is a type of fuel gas used in oxy-fuel welding and cutting torches, comprising a mixture of several gases. MPS gases [ edit ]

5. Flashback arrestor - Wikipedia

   en.wikipedia.org/wiki/Flashback_arrestor

   A flashback arrestor or flash arrestor is a gas safety device most commonly used in oxy-fuel welding and cutting to stop the flame or reverse flow of gas back up into the equipment or supply line. It protects the user and equipment from damage or explosions. These devices are mainly used in industrial processes where oxy-fuel gas mixtures are ...

6. Blowtorch - Wikipedia

   en.wikipedia.org/wiki/Blowtorch

   The term "blowtorch" is commonly misused as a name for any metalworking torch, but properly describes the pressurized liquid fuel torches that predate the common use of pressurized fuel gas cylinders. Torches are available in a vast range of size and output power. The term "blowtorch" applies to the obsolescent style of smaller liquid fuel torches.

7. Underwater cutting and welding - Wikipedia

   en.wikipedia.org/wiki/Underwater_cutting_and_welding

   Oxygen arc cutting and arc welding underwater requires greater skill and stamina than working in a dry and stable environment. The underwater environment imposes several limitations and restrictions on both the equipment and the operator, and the restriction of short bottom times at greater depths for surface-oriented divers makes efficient working important to getting the job done in a ...
