What types of flame are obtained in oxy-acetylene gas welding?
In oxy-acetylene gas welding, three types of flames can be obtained: carburizing flame, neutral flame, and oxidizing flame. Carburizing flame has excess acetylene, neutral flame has perfect balance of acetylene and oxygen, and oxidizing flame has excess oxygen.
Which gas welding flame is the hottest?
The neutral flame in gas welding is the hottest, reaching temperatures up to 6300°F (3482°C). This flame is achieved by mixing equal parts of oxygen and acetylene, providing the ideal balance of heat for welding.
What shade is used for gas welding?
Depends on the type of material to be welded, the size of the flame, and in my situation slowly deteriorating eyesight. Basically shade 4 or 5 will be adequate. As dark as 6 on aluminum. You will be able to tell if you aren't using a dark enough shade as you can get a "flash" ( Like a sunburn on the eyes). Start with a #5 and go from there.
Which welding process required o2 gas?
Oxy-fuel welding is a welding process that requires O2 gas. It uses oxygen and a fuel gas, such as acetylene, to create a high-temperature flame for the welding process. The oxygen supports combustion and helps create the heat needed to weld the materials together.
How do you gas weld?
To gas weld, you'll need a gas welding torch that mixes fuel gas with oxygen to create a flame. The workpiece is heated with the flame until it reaches the melting point, and a filler rod is added to create a bond between the two pieces. Practice and proper safety equipment are essential for successful gas welding.

What are the enviornments of welding?
The environments of welding could be one of the following:- open air- outer space- under waterthese different environments need different energy sources like gas flame, an electric arc, gas flame or laser.

What is the principle of gas welding?
Gas welding involves using a fuel gas, like acetylene, and oxygen to create a flame that melts and joins metals. The principle behind gas welding is to generate intense heat from the combustion of the fuel gas and oxygen to melt the base metals, allowing them to fuse together. The process requires precise control of the flame temperature and welding speed to achieve a strong and clean weld.
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 hot is gas flame when welding?
A gas flame in welding can reach temperatures ranging from 3,000°F to 6,300°F (1,649°C to 3,482°C) depending on the type of welding process and gases used. These high temperatures are necessary to melt and fuse metal together during the welding process.
What is the function of the needle valves on a welding torch?
To adjust gas flow therefore adjusting flame intensity.
What is the flame that is used for cutting and welding of metals?
The flame used for cutting and welding of metals is typically a combination of oxygen and a fuel gas, such as acetylene or propane. This flame produces high temperatures that can melt and join metal pieces together or cut through metal with precision.
What is the difference between oxy-acet welding and lpg welding?
Oxy-acetylene welding uses a mixture of oxygen and acetylene gases for the welding process, producing a very hot flame. LPG welding uses liquefied petroleum gas (propane or butane) as the fuel source for the flame. Oxy-acetylene welding typically produces higher flame temperatures and is often used for cutting as well.
