What is acetylene welding?
Acetylene welding is a process in which like metals are joined by heating them to their melting temperature with an oxy-acetylene flame produced by a torch.
What happens when acetylene is bubbled through bromine water?
Acetylene will change colour from orange to colourless.
What types of flame are obtained in oxy-acetylene gas welding?
When the correct amount of Oxygen is mixed with the Acetylene a NEUTRAL flame is produced. Less than that amount produces a CARBURIZING flame. Too much Oxygen creates an OXIDIZING flame. Most welding/cutting is done with a NEUTRAL flame but all flame adjustments have their purpose.
What are the three types of acetylene welding flames?
Mixing Acetylene and Oxygen in the correct proportions produces an extremely hot flame. Using just enough Oxygen so that the Acetylene is almost completely consumed in the flame is called a Neutral Flame. In most welding and cutting applications you would utilize this flame. Reducing the amount of Oxygen produces a Carburizing Flame. It is yellowish and not as hot as a Neutral Flame, but, is used in certain situations. Welding Aluminum is one. Increasing the Oxygen produces an Oxidizing Flame. It produces a flame that is pointed, colder, and louder than a Neutral Flame. It wastes fuel and isn't as efficient as a Neutral Flame.
Why for welding use oxygen and acetylene?
Because of all the gas combinations used with this process Oxygen and Acetylene, in correct proportions, produce the highest flame temperature.
How can an oxygen-acetylene torch burn underwater?
a flame needs a source which is provided by oxygen and acetylene

What element is used in oxy-acetylene flame?
dhjfuddidhusysu
What is the oxygen to acetylene ratio in oxidising flame?
it is 1:0.8

What colour are hoses for an acetylene cylinder?
red

How hot does rocket fuel burn?
6,300 degrees fahrenheit which is the same temperature as the oxy-acetylene cutting torch flame and in fact the oxy-acetylene cutting torch flame looks exactly the same as the rocket engine flame. Vincent Majerowicz
What gas is used in a flame thrower?
Ozone and acetylene
Which flame is used for welding brass?
natural flame using a mixture of one-to-one ratio of acetylene and oxygen.

What kind Of Carbide is needed for lamp?
Calcium Carbide is used in "Carbide Lamps". Water, added dropwise to Calcium Carbide yields acetylene plus calcium hydroxide. Acetylene is extremely flammable, giving a colorless flame. The calcium hydroxide present gives the flame its visibility. Calcium Carbide is used in "Carbide Lamps". Water, added dropwise to Calcium Carbide yields acetylene plus calcium hydroxide.
