speed or better cut quality. Cutting speed on a thin plate (less than or equal to 1/2”) is controlled by preheat intensity (flame temperature) and in heavier plate cutting by oxygen stream shape and quality, not the fuel type. Quality of cut is a function of oxygen stream and cutting speed. sectiOn 2 preheat

Safety in gas welding, cutting and similar processes Page 7 of 11 Protecting cylinders from flashbacks Fit flashback arresters to both the oxygen and fuel gas hoses near to the regulators. For long lengths of hose, fit arresters on both the torch and the regulator. The fitting of a flashback arrester is not a substitute for safe working practice.

Cutting with the oxy-fuel process is just the opposite from of welding. Oxy-fuel cutting uses acetylene and oxygen to preheat metal to red hot and then uses pure oxygen to burn away the preheated metal. Because this is achieved by oxidation, it is only effective on metals that are easily oxidized at this temperature. Such metals are mild steel and
Oxygen purity is vital to efficient production. For example, 99.5 percent pure oxygen can produce high-quality, flame-cut edges. A drop of one percent in oxygen purity slows cutting speed 25 percent. At 95 percent oxygen purity, an oxy-fuel cutting torch will not cut steel at all. Cylinder oxygen is produced from vaporized liquid oxygen.
• in oil pre-heating burners- these burners are set to burn with should oxygen enter the fuel gas hose or should fuel gas enter the oxygen hose, a mixed gas explosion with the force potential of 20 sticks of dynamite could fuel valve. Cutting Tips And Nozzles • Allow the nozzle to cool before using.
Process fundamentals. The cutting process is illustrated in Fig. 1. Basically, a mixture of oxygen and the fuel gas is used to preheat the metal to its 'ignition' temperature which, for steel, is 700°C 900°C (bright red heat) but well below its melting point.
30-9-2012· Diesel & fuel oil boil above 300f [not all that hot]. Fuel vapor + oxygen goes bang if the mixture is anywhere near right or just flares up and singes all the hair off Your body if the mixture is way off. When I was a kid I was brazing an oil pan still attached to the engine under the car.
Broco ® Industrial Cutting . Utilizing only oxygen, Broco rods quickly cut or melt cast iron, steel, stainless steel, concrete, granite, nickel, titanium, aluminum and exotic metals. Broco exothermic systems cut so quickly there is minimal heat build-up so material temper remains virtually unchanged.
It is important to oil the threads on the oxyfuel connections to keep them working properly. FALSE. It is never acceptable to blow dust off your clothing with oxygen. The correct AWS term to describe the fuel gas and oxygen cutting process is __. OXYFUEL GAS CUTTING. When oxygen working pressure is being set on a regulator,
Start studying Oxy-Fuel Cutting. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Search. A liquid petroleum fuel, which comes from oil refineries or as a gas off the top of oil wells. larger hole provides the high velocity oxygen for cutting.
OSHA Self Inspection Checklist Welding and Cutting with Oxygen Fuel Gas OSHA Self Inspection Checklist Welding and Cutting with Oxygen Fuel Gas . General Requirements. 1. Is acetylene generated, piped, or used at pressures no greater than 15 psig (pounds per square inch,

Oxy fuel cutting ：Cutting method that melts and remove Iron by the oxidation reaction heat of the Iron itself. Cutting Oxygen Pre-heat Flame Slag Cutting tip Reaction point Cutting direction 1. Heat the Iron by Pre-heat Flame. 2. When the Iron exceeds the combustible temperature, it starts to combust by the Cutting oxygen, and Reaction point is
B. Oxy-fuel Gas Safety 1. Always refer to oxygen and acetylene by their proper names. 2. Never use oxygen or fuel gas from a cylinder except through an approved pressure-reducing regulator. 3. Connect regulators only to cylinders for which they were designed. Oxygen regulators to oxygen cylinders and acetylene regulators to acetylene cylinders. 4.
6-4-1979· Oxygen cylinders in storage shall be separated from fuel-gas cylinders or combustible materials (especially oil or grease), a minimum distance of 20 feet (6.1 m) or by a noncombustible barrier at least 5 feet (1.5 m) high having a fire-resistance rating of at least one-half hour.
