Which gases are used in gas welding Mcq?

Which gases are used in gas welding Mcq?

Explanation: In gas welding, acetylene is used as a fuel gas which produces hot flame when it is mixed with oxygen.

Which gas is not used in gas welding?

Firstly: Propane cannot be used for Gas Welding. When acetylene burns in oxygen, it creates a reducing zone that cleans the steel surface. Propane do not have a reducing zone like acetylene and can hence not be used for Gas Welding.

Which gas is used with oxygen in welding?

Acetylene
Excellent Welding Quality: Acetylene is the hottest fuel gas when combined with oxygen. In the right applications, this makes acetylene ideal for welding different steel materials.

Answer» c. Black

Which gas is used in TIG welding?

argon
In the TIG welding process the arc is formed between a pointed tungsten electrode and the workpiece in an inert atmosphere of argon or helium.

Which gas is name as blue gas?

noun. A gas consisting mainly of carbon monoxide and hydrogen, made by passing steam over red-hot coke and burning with a blue flame, used especially as a source of hydrogen; also called blue gas, water gas.

Which gas is used in welding and cutting?

Acetylene is the primary fuel for oxy-fuel welding and is the fuel of choice for repair work and general cutting and welding. Acetylene gas is shipped in special cylinders designed to keep the gas dissolved.

Which gas is used in welding of metals?

Ethyne is used for welding and cutting of metals. The welding process which uses ethyne is called as gas cutting or oxy – fuel cutting. In this method, materials are weld or cut at a very high temperature around 3500∘C .

Which are gasses used in normal welding process?

Argon Gas. Argon is a nonflammable,nontoxic,inert gas; therefore,it is known not to have any chemical reaction when it comes into contact with other materials and even

  • Oxygen. Oxygen is one of the most popular gases known,which makes combustion possible and also supports life.
  • Acetylene Gas.
  • Carbon Dioxide.
  • Helium.
  • Hydrogen.
  • What is the most common gas used for GTAW or TIG welding?

    GTAW (TIG) Gases: TIG welding shielding gases are going to be argon or helium, or a mixture of the two. But argon is the most commonly used shielding gas for TIG welding. If you want a more stable arc and good cleaning action then argon is the gas you want for TIG welding.
