2C2H2(g) + 5O2(g) = 2H2O(g) + 4CO2(g) or, 2 Acetylene molecules + 5 Oxygen molecules = 2 water molecules + 4 Carbon dioxide molecules (+ energy)

Which gasses used in normal welding process?

The gases commonly used in welding are oxygen, acetylene, argon, and carbon dioxide. These gases play different roles in the welding process, such as providing heat, shielding the weld from atmospheric contamination, and facilitating the arc.


Which element is used in welding with oxygen?

Acetylene is commonly used in welding with oxygen to create a high-temperature flame for cutting and welding metal.


What is a reaction between acetylene and oxygen that is used in welding metal?

The reaction is called oxyacetylene combustion. It involves the burning of acetylene gas (C2H2) and oxygen (O2) to produce a high-temperature flame used for welding and cutting metals. The reaction forms carbon dioxide (CO2) and water vapor (H2O) as byproducts.


What is the flame commonly used in gas welding?

Oxy-Acetylene. A mixture of oxygen and acetylene. Commerically it is still acetylene, however, its chemical name is 'ethyne'. Its structure is 'H-C///C-H'. NB The symbol '///' repreent a triple bond between the two carbons.


What are two gases used in oxy-acetylene welding?

You answered your own question. Oxygen and Acetylene. Other mixes are now used in place of Acetylene so the process is now called Oxy-Fuel.


What is acetylene welding?

Acetylene welding is a process that involves using acetylene gas as a fuel combined with oxygen to produce a high-temperature flame for joining metals together. The flame generated by burning acetylene with oxygen can reach temperatures up to 3,100 degrees Celsius, making it effective for welding tasks.


What is the gas for welding?

Oxygen and acetylene for flame welding. Argon for Tig welding CO2 for MIG welding steels Argon for MIG welding aluminum TRI-mix for robotic mig of steels. And helium is added for some overhead welding.


Which compressed gases are used for welding?

Some common compressed gases used for welding include acetylene, argon, carbon dioxide, and helium. These gases are often used in various combinations depending on the welding process and materials being joined.


Which two gases mixed and used as fuel in welding?

n - Oxygen and Acetylene are the original gasses that are used for welding/cutting. Newer mixtures are slowly replacing Acetylene as a fuel. These gasses don't always reach the temperatures attained by Acetylene. Us old-timers still prefer Acetylene.


What is welding gas?

Welding gas can refer to two things. In torch welding, it is either a fuel gas such as acetylene or MAPP or oxygen, and in arc welding (MIG, TIG, etc...) it refers to any of the inert gases such as carbon dioxide or argon that is pumped over the weld pool to protect it from atmospheric contaminants.


What is the industrial use of acetylene?

Acetylene uses:- welding- metals cutting- feedstock for plastics and acrylic products fabrication


Why for welding use oxygen and acetylene?

Oxygen and acetylene are commonly used for welding because they create a high-temperature flame that can melt and join metals together effectively. The mixture of oxygen and acetylene provides a clean and precise flame, making it suitable for various welding applications. Additionally, the high heat produced by the oxy-acetylene flame allows for efficient welding of thick metal sections.
