Why welders use welding torch instead of flame of firewood?
An oxy-acetylene welding torch is used for welding rather than a flame from firewood because it is possible to concentrate the energy and heat at one small precise location, to move it readily, to generate a lot of heat in one small area, to control the amount of heat precisely, and to control the amount of oxygen in the flame and therefore the oxidation occurring at the weld.
How hot is a welding torch flame?
A welding torch flame can reach temperatures between 1,500°C to 3,500°C (2,732°F to 6,332°F), depending on the type of fuel and the welding process used. For example, an oxy-acetylene torch can produce a flame that exceeds 3,200°C (5,792°F). The intense heat allows for the melting and joining of metals effectively during welding operations.
What is the function of the needle valves on a welding torch?
To adjust gas flow therefore adjusting flame intensity.
Explain oxy- acetylene welding process?
Oxygen and acetylene tanks feed into your torch. When opened, the gases will mix in a chamber in the torch, then flow out of the torch tip. Using a spark lighter, they will ignite causing a flame. This flame can be adjusted to a neutral flame by moving the knobs on the tank regulators.
What are facts about welding?
# If you look into the flame you'll go blind, # if you touch the flame it will burn you, # your face is always hotter than your buttocks, # a cigarette always tastes better when lit by a torch flame, # always weld with a full gas tank, # you can get a tan/sunburn from welding, and # welding is fun when you weld random items together.
How much do welding machines cost?
Depending upon the type of welding machine, its cost varies from Rs50.000 to more than Rs 1,00,000. Manufacturers like Artech welders, Roteckweld offers welding machines at affordable cost.
Who invented the welding torch?
John T. Herrera: The Welding Torch Inventor
Which gas burns the hottest when cutting torch is used?
oxygen supports the combustion of the gas that one uses in the welding/cutting torch. Acetylene combined with Oxygen produces the hottest flame.
What is a welding helmet?
The helmet takes the place of a safety helmet and gives a firm attachment to the flip-up visor. When welding the visor is dropped to protect the eyes from the light coming from the welding torch. It is obviously difficult to see anything through the visor except the filtered welding torch flame. The visor can be flipped up to let the welder clearly see the result of the weld, or to move to another spot.

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 a turbo tourch used for?
A turbo torch is is a welding tool used in the HVAC (Heating, Ventilation and Air Conditioning) field. The torch can use propane or oxy-acetylene gas to provide a high temperature flame.
