Low carbon steel low alloy steel e g cast steel and wrought iron are easily welded with the oxy acetylene flame Low carbon and low alloy steels are the ferrous materials that are gas welded most frequently As the carbon content of steel increases it may be repaired by welding using specific procedures for various alloy types The oxy acetylene and other oxy fuel gas mixtures welding torch remains a mainstay heat source for manual brazing and braze welding as well as metal forming preparation and localized heat treating In addition oxy fuel cutting is still widely used both in heavy industry and light industrial and repair operations Jul 18 Make sure that the metal is clean dry and free of any grease or oil Step 4 Introduce the Filler Rod Welding the pieces will typically require the use of a bronzing rod You can place the rod on the seam of the aluminum pieces that you intend to weld and then work the torch flame on the filler by holding the flame a few inches above the rod Hello friends This is video is a knowledge for welding tips USE ALL WORK THAM See my video I am make to welding tips for your knowledge If you Oxygen and acetylene in approximately equal proportions are burnt at the small jets this flame is used to preheat the work to about °C At a temperature of °C Iron and Steel easily combine with the oxygen to form oxides and burn rapidly away the cutting zone It is the hottest flame produced by any oxy fuel gas source Such a flame may oxidise the metal in the weld pool producing a weld bead with scummy or dirty appearance An oxidising flame is used for welding copper base alloys zinc base alloys and a few of the ferrous metals such as manganese steel and some of the cast irons In fact the oxy acetylene flame burns at ° F and is the only gas flame that is hot enough to melt all commercial metals 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 Jan 08 The hottest flame is violet on the color spectrum and white in the visible spectrum The type of fuel and impurities in addition to the flame temperature contribute to the color of the flame Once the gas forms combustion occurs as the various molecules react with oxygen to produce the heat and light known as fire Other Welding Fuels Though not strictly used for oxyacetylene this is a good time to discuss other welding fuels For economy and safety reasons other gases such as natural gas propane hydrogen and proprietary gases based on mixtures of these are frequently used for non welding processes

What kind of flame is used in gas welding

The Harris Products Group is a world leader in metal working products used in the brazing soldering welding cutting and gas distribution industries The company was formed in with the merger of Harris Calorific Inc a manufacturer of gas welding and cutting equipment and gas regulation and distribution systems and the J W Harris Co May 01 Welding arcs give off radiation over a broad range of wavelengths from nm nanometres to 1 nm or 0 2 to 1 4 µm micrometres These ranges include ultraviolet UV radiation to nm visible light to nm and infrared IR radiation to 1 nm A Neutral Oxy Acetylene Flame is used for Welding Brazing and Silver Soldering most metals and is therefore the most common type of flame to use A Neutral Flame is also used for Oxy Acetylene Cutting Oxidising Oxy Acetylene Flame An Oxidising Flame is where there is more Oxygen than Acetylene used Lighting and adjusting the torch with a positive/equal pressure mixer Separately purge both oxygen and fuel gas lines Open fuel gas valve 1/2 turn Ignite flame with striker Increase fuel gas flow until flame leaves end of tip and no smoke is present Decrease until flame goes back to tip Open oxygen valve and adjust to neutral flame Oxygen/Acetylene welding or “Gas Welding” is a process which relies on combustion of oxygen and acetylene When mixed together in correct proportions within a hand held torch or blowpipe a hot flame is produced with a temperature of about 3 °C The chemical action of the oxy/acetylene flame can be adjusted by changing the ratio of the volume of oxygen to acetylene using the valves on the torch or blowpipe Oxyacetylene welding commonly referred to as gas welding is a process which relies on combustion of oxygen and acetylene 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 deg C check the pressures on regulators re light the torch using the recommended procedure If the flame continues to burn close the oxygen valve at the torch to prevent internal burning close the acetylene valve at the torch close cylinder valves or gas supply point isolation valves for both oxygen and acetylene When oxy acetylene welding you must keep two things in mind when adjusting the flame 1 How much gas is going through the tip 2 The r In oxyacetylene welding the two gases used for producing flame are oxygen and acetylene Oxygen is used to support and intensify combustion It is generally prepared in factories by liquefying air and then separating it into its component parts by rectification

What Is Oxy Acetylene welding Oxy Fuel Welding

Control the pace so everyone advances through each question together Which of the following is the flammable gas used in the oxyacetylene welding process Which of the following flames contains too much acetylene Which of the following flames contains too much oxygen This flame has a ratio of oxygen and acetylene at almost 1 to one May 23 Thomas Wilson created the oxyacetylene torch in He combined both pure oxygen 99 5% and acetylene in proper proportions to yield a flame of about 3 degrees Celsius Oxyacetylene the only gas mixture that will burn hot enough to cut steel Click to see full answerMar 19 A Neutral Oxy Acetylene Flame is used for Welding Brazing and Silver Soldering most metals and is therefore the most common type of flame to use A Neutral Flame is also used for Oxy Acetylene Cutting Oxidising Oxy Acetylene Flame An Oxidising Flame is where there is more Oxygen than Acetylene used The oxyacetylene welding process uses a combination of oxygen and acetylene gas to provide a high temperature flame In oxyacetylene welding the flame produced by the combination of the gases melts the metal faces of the work pieces to be joined causing them to flow together In an oxidizing flame generally used in cutting operations there is more oxygen than the acetylene can use The heated oxygen can and will react with the metal being heated causing some of it to burn away Most oxy acetylene welding is done on carbon steels There are fluxes for stainless and aluminum but they are not common Students progress at their own pace and you see a leaderboard and live results Control the pace so everyone advances through each question together Which of the following is the flammable gas used in the oxyacetylene welding process Which of the following flames contains too much acetylene • Never starve or choke a multi flame heating nozzle This causes overheating of the head and a flashback may result • Should a flashback occur flame disappears and/or a hissing sound is heard the flame is burning inside the nozzle immediately turn off the oxygen valve on the torch handle Then turn off the fuel valve An oxy acetylene cutting torch allows oxygen to mix with acetylene to combust and produce a flame that has a temperature exceeding C This kind of flame is the only one hot enough to cut through mild steel specifically any kind of steel that only has a maximum of 0 3% carbon 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 It& 39 s easy to learn The equipment is cheaper than most other types of welding rigs e g TIG welding
