Neutral Flame: Pressure oxygen and acetylene the same. Oxygen is obtained from the air where the air itself contains oxygen (21%), also contain nitrogen (78%), argon (0.9%), neon, hydrogen, carbon dioxide, and other elements that form a gas. Each gas is controlled by the valve present on the torch. With the right Gas Welding Equipment you can Gas Weld, Braze, Silver Solder, Heat and Oxygen + Acetylene or Oxygen + Propane Cut. In the commercial world, to produce a reaction Oxyacetylene do activities calcium carbide and water. The filler rod is moved forward in a circular motion, with the blowpipe moving steadily along the seam of the weld. This flame is not used to weld regular steel. Oxy-Acetylene Welding of Cast Iron. The welder is also given complete freedom to move and a clear view of the fusion zone and weld pool. Today, oxy-acetylene welding is employed for high strength steels. Oxy-Acetylene Welding Oxy-Acetylene, commonly known as Oxy-fuel, is one of the . It is one of the most versatile types of welding. The filler rod is preceded by the flame in the direction of the travel. Learning how to weld using this process will give a complete overview of welding. Different types of flames are used to weld different types of metals. I've learned from hands-on experience what welding gear works and what doesn't. Therefore, Oxyacetylene often called hydrocarbon gas consisting of carbon, lime, and water. Oxy fuel or oxy acetylene welding are gas welding procedures that were invented in the early 1900's. The primary components of Oxy-Acetylene welding equipment are separate gas cylinders for oxygen and acetylene. 3. Start by opening the valves of oxygen and acetylene gas cylinders gradually, with the help of cylinder keys. There are different types of techniques that you can practice, which have been listed below: The leftward technique of Oxy-Acetylene welding is employed to weld steel plates that are up to 5mm thick. The flame heats the base metal to its fluid or puddle state. There are specially-designed devices called Flashback Arrestors that are fitted between the regulators and hoses as a safety measure. We have listed down the most common hazards of this type of welding below: Gas welding is one of the riskiest of all types of welding. Oxyacetylene Welding (OAW) The oxyacetylene welding process uses a combination of oxygen and acetylene gas to provide a high temperature flame. Oxy … After the pressure of the gases has been regulated and controlled, they are fed to the welding torch through the respective hoses. Oxyacetylene Welding (OAW) • by WAQAS AHMED 2. The pressure regulator controls the pressure and the flow of gases. They are ignited and burned at the nozzle of the torch. The two gases are not chemically combined but rather a mixture which is prepared only for a specific purpose – superheating. So that needs oxygen purification repeatedly. For our full range, visit our website or call 0800 195 1313 today. You should make sure that you do not keep the filler rod dipped into the pool continuously as it would act as a hindrance to thorough heating and keep the heat from the flame to reach the lower parts of the weld, and this might result in an imperfect fusion. Oxy-acetylene welding is a very common welding process that dates back to 1890s, wherein oxygen and acetylene are used as the two major welding gases. The mixture can be explosive, depending upon what percentage of oxygen is involved. If there is any damage to it, the gas will start to leak. Navy FR Cotton... Reusable Half Face Cover, NASUM M101 Face Cover,... Make sure that you’re always wearing protective clothing (flame-retardant overalls) and protective eye goggles, The acetylene gas cylinder valve should have a spindle key, The gas cylinders should be stored in an upright position, Check for leaks with a soapy solution and not with a naked flame, Do not carry out any makeshift repairs on your welding equipment, Prevent the contact of your oxygen equipment with oil or grease at all times, Clean enclosed vessels thoroughly before welding them, If you’re working in an enclosed vessel, make sure you aren’t alone and that the gas cylinder is always outside, Fire-fighting equipment should be available on the ground, Turn the gas supply off immediately if you detect a leak in the hose. Oxygen Acetylene Welding (OAW) Process and Equipment: Oxy Acetylene Welding Set Up and Pressure Settings Chart : Shielded Metal Arc Welding Machine Parts And Process. Keep in mind that pure Oxyacetylene is very susceptible to an explosion caused by pressure and temperature factors. Every hose has a check valve that offers automatic safeguarding by incorporating a non-return valve. The gases are transported from the gas cylinders to the welding or cutting torch through hoses, and the flame is emitted through the nozzle at the end of the torch. And this welding process is still very popular today, mainly because it does not require much equipment, and does not require power. Gas welding uses tanks of compressed oxygen and fuel—most commonly acetylene—feeding these gases through hoses to a handheld torch, producing an extremely hot and easy-to-control flame. The final flame should have a sharply defined, white-colored inner cone with as little trace of acetylene haze as possible. It cannot be used to weld steel as it will oxidize it. Flame traps (also called flashback arresters) must be fitted into both oxygen and acetylene gas lines to prevent a … The metals that are welded with Oxy-Acetylene include low-alloy steel, low-carbon steel, wrought iron, and cast iron. … Oxyacetylene nature is odorless and colorless.

However, if the proportions are harnessed and modulated properly, the combustion of these two gases can produce heat and light. Once the flame ceases to smoke, increase the oxygen supply slowly by means of the control valve. Rods that contain tungsten carbide are deposited using this technique. Besides acetylene gas is also used hydrogen gas, natural gas, propane, for metals with a low melting point. Any guide on how to Oxy-Acetylene weld will be incomplete without highlighting the hazards of Oxy-Acetylene welding. These mighty metallic structures are heavy and solid. However, has it ever crossed your mind how metals are joined together to form such marvelous structures? This site is owned and operated by Muller Media LLC. Purity can be achieved up to 99.5% and then used in steel tanks with a working pressure of 15-30 atm. Oxy acetylene welding kit is of a great a pplication but people get injured every year because of its improper and incorrect application. When mixed together in correct proportions within a hand-held torch or blowpipe, a relatively hot flame is produced with a temperature of about 3,200 deg.C. Note Acetylene is supplied in cylinders under a pressure of about 15 bar but welding is carried out with torch gas pressures typically up to 2 bar. OXY-ACETYLENE WELDING It is the common method of gas welding. Muller Media LLC is compensated for referring traffic and business to these companies. If Oxy-Acetylene welding is done the right way, it can be used to weld all commercial metals. Carburizing flame contains an excess of acetylene gas. This type of flame is suitable for applications where a low-heat flame is required. The gas should be lit using a suitable spark-lighter only, and that too, held at the right angles to the nozzle. The temperature of the flame is hot enough to melt the edges of the metal, and hence, fuse two metal pieces together. Gas welding poses a significant risk of accidents. Neutral flame contains equal proportions of oxygen and acetylene gases. Oxy-fuel equipment is versatile, F. With the addition of Oxygen a flame temperature in excess of 6000 deg. Video for my high school students to follow as they learn the process of using the Oxy-Acetylene torch. Now you know, what is Oxy-Acetylene Welding. A few years ago I got really into welding as a side hustle. RG is Rod Gas and 65 is tensile strength 65.000 PSI. For this very reason, you should always open the gas cylinder valve smoothly and slowly with the help of the Spindle Key. This type of flame is used in most welding operations since the chemical effect of this flame on heated metal is the least. It is used for welding nickel, Monel metal, high-carbon steel, and a number of non-ferrous metals. An Oxy-Acetylene outfit is portable, less expensive and more versatile than a electric welding … Welding joins different metals together by heating them at the junction up till the point they melt and fuse together. If the gas has out from nozzle you can use lighter and light the torch. The welding starts at the bottom of the plate and proceeds up vertically. This is where welding comes into play. This technique has widespread applications in building up wear-resistant surfaces on dyes, well-boring drills, punches, knives, picks, valve seals, and excavating and crushing machinery. At this point, the rod is melted onto this sweating surface in small deposits. Oxy-Acetylene Welding 101 Print Article Welding is a fundamental skill needed for many truck modifications and repairs. This type can we use for steel. The gland nut around the cylinder valve should be tightened clockwise using a spanner to ensure that no gas is leaking, thereby reducing the risk of accidents. The nozzle is moved in slightly side-to-side or circular motions to ensure consistent heating and achieve an even fusion. The most commonly used rods include fluxobronze, which is a silicone bronze rod that has been flux-coated, manganese bronze rod, and plain nickel bronze rods with suitable flux. ESAB Turbo Torch kit. In addition to the purposes of welding (connecting), gas welding can also be used as preheating, brazing, cutting, and hard facing. The supply of acetylene gas to the blowpipe should be adjusted up to the point the flame stops to smoke. The torch will be re-ignited instantly. Technically, the oxygen is obtained from liquefied air. Greater nitrogen boiling point and the boiling point of the gas is the only difference 13 0C only. Required fields are marked *. It is the welding or cutting torch where the two gases, oxygen, and acetylene finally mix. Oxyacetylene welding, commonly referred to as gas welding, is a process which relies on combustion of oxygen and acetylene. Welding (Fusion) Welding/fusion is the #3 most widely used process of the gas torch outfit. Almost every welder knows how cool it is to use an oxy-acetylene torch for welding and cutting, heating, and soldering metal with ease. Since steel melts at about 1,500℃, the mixture of oxygen and acetylene is the only gas combination that generates enough heat to melt steel. As is the case in other welding processes, welding defects can occur. The oxy-acetylene welding process combines oxygen and acetylene gas to provide a high temperature flame for welding. Then, by means of electrolysis, a mixture of air and water are separated by liquid oxygen. The kit is an excellent kit for a first time user since it is beginner-friendly. Oxy-acetylene Welding is one of the most common forms of welding in use throughout industry. How to properly light, adjust and shut down an oxy–acetylene torch Harris Products Group. This program shows operators how to use Oxy-acetylene equipment safely and correctly. What Is Oxy-Acetylene Welding? Safety: The efficiency of acetylene when used with oxygen is very high. Description. As you can tell by the name, an oxidizing flame has a high content of oxygen (the oxygen and acetylene ratio being 1.5:1). It is a device that saves acetylene and oxygen from being wasted when the welding or cutting torch is not in use. This means that the gasses, especially the oxygen, lasts longer. This equipment is super easy to use and minimizes the welding cost dramatically. Carburizing Flame: For this type, we use more acetylene than oxygen. It is a suitable technique for mild steel pipes and plates in a vertical and overhead position. For welding or cutting, using Oxy-fuel is not only a common method to apply in a workshop but more than it. Then, heat these touching edges with a flame till they melt and fuse. http://bit.ly/VAj0py When oxy acetylene welding you must keep two things in mind when adjusting the flame: 1) How much gas is going through the tip. Oxy-acetylene welding is simple in concept - two pieces of metal are brought together, and the touching edges are melted by the flame with or without the addition of filler rod. ADVERTISEMENTS: Subject-Matter of Oxy-Acetylene Cutting Process: In modern steel-age the steel-makers cut Iron and Steel by oxy-acetylene, oxy-hydrogen, oxy- propane, oxy-natural gas cutting blowpipes easily, speedily, and cleanly. Gas Welding is probably the oldest of the Welding processes and Gas Welding Equipment is arguably the most versatile. Although it depends on the application, generally, oxygen should be set at 40 psi, and acetylene should be set at 10 psi. In the process of burning the gases needed oxygen. Oxy-acetylene flame may also be used for all types of brazing. Oxy acetylene welding 1. To support all the weight they have to and remain strong and sturdy, different metals need to be fused to combine the strengths of both materials. Use for production, fieldwork, and reparations. Your email address will not be published. To re-light the torch, all you have to do is remove the welding torch from the lever rod and pass it over the pilot light. As the welding procedure proceeds, simply dip the filler rod into this molten pool. Oxy welding involves the combustion of oxygen and acetylene through a hand-held torch. Opening the valves suddenly can not only damage the regulators but might also lead to an accident. However, it is still widely used for a variety of applications. Save my name, email, and website in this browser for the next time I comment. The difficult problem is between Nitrogen and Oxygen. Oxy-Acetylene welding involves joining two metals with the help of a flame produced by the combustion of oxygen and acetylene. Oxy-acetylene welding of cast iron is comparatively easy, if attention is paid to some simple rules. The filler rod should not be melted by direct flame but by dipping into the molten weld pool only. Lighting, adjusting and shutting down an oxygen-acetylene torch is easy – especially when following the proper procedures. The rightward technique is faster as compared to the leftward technique.
