If your question is "Why is Acetylene and Oxygen used for welding/cutting NOT Oxygen and air"? This is why. Acetylene and air mixed in correct proportions produces a flame temperature of 4500F to 4800F degrees. Acetylene mixed with Oxygen in the correct proportions produces a flame well above 5500F degrees. This extra heat melts the metal faster and increases the speed you can cut or weld. Other gasses instead of Acetylene are used but do not produce as high a temperature. Oxygen is almost always used with these other gasses.

How is oxygen used used in welding?
Oxygen is used to produce hot flame which is used in welding purpose
Why is no number used in the names ethene and propene?
ethene: CH2=Ch2 propene: CH2=CH3CH There is nowhere else to place a double bond! (C=C) No number is used in the names ethene and propene because the number would be useless as the double bond is located at carbon "1"
What welding rod is used for welding manganese and carbon steel?
720
Is ethene ionic or covalent?
Covalent, ethene has a double bond, C2H4
Why is argon gas used in welding?
Argon is used in welding to prevent oxygen from entering the weld site. Oxygen is basicly bad for the weld and Argon displaces the oxygen which results in a better weld (less heat stress, less air pockets (imperfections in the weld) etc.)
What type of welding machine use in spot welding or resistance welding?
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
The electrode holder used for shielded metal-arc welding may not be used carbon arc welding?
Any electrode holder that will accommodate the size of rod can be used. Twin Carbon Arc Welding requires a specific holder. Air Carbon Arc Gouging requires a special holder that also supplies a stream of air.
Which tets coudl be used to distinguish between ethene and methane?
Ethene can react with Bromine water - turns colourless
What happens to the argon gas when used in welding assuming it does not burn does it just dissipate into the air?
It just dissipates into the air.
Would air or argon have a higher density?
Argon has a higher density than air and is used in welding applications to displace air (oxygen) from the weld.
Resistance welding is commonly used in production welding operations?
Yes, resistance welding is used in production welding. It is used extensively in the automotive industry.

What element is found in air craft automobiles welding and cooking utensils and is used to transmit electricity?
Aluminum.
What are welding electrodes used for?
Welding Electrorodes or Welding Rods are used in arc welding. Arc welding is a special type of welding which uses a welding power supply to create an electric arc between the base material (e.g. steel) and the electrode. The Welding Ectrorodes can be used for all weldable aluminum and mild steel.
Is propylene used in welding?
Yes, propylene (propene) can be used for welding.
Which welding machine should be used for earth mat welding?
Exothermic Welding is used for earth mat conductors
What is the raw material used to obtain ethane by hydrogenation?
ethene
