You can weld with acetylene, which burns very well; argon is inert and doesn't burn at all, so it is useless for welding.

Acetylene Torch?
form_title= Acetylene Torch form_header= Do all of your own welding with a new Acetylene Torch. Have you ever used a Acetylene Torch?*= () Yes () No How many do you want to buy?*= {1, 2, 3, 4, 5, More than 5} Are your welding needs for commercial or personal use?*= () Personal () Commercial
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.
Which is the highly inflammable gas in LPG?
Propane, which has a lower flash point than butane.
Which has a lower boiling point butane or water?
benzene has lower boiling point than water

What are the Gauge pressures when oxy welding?
oxygen...25psi acetylene....7-10psi. Never go higher than 15psi with acetelyne. it will become highly volitile
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.
Is a number five lens darker than a number ten lens?
No the higher the number the darker the lens. 4 or 5 for gas (oxy/acetylene) welding. 9 for small TIG work and 10 - 11 - 12 for stick welding.
Why is the oxyacetylene process used sparingly in today's industry?
when you are in the field you dont always have access to acetylene, also it is less effective than arc welding, and its more dangerousAnother reason: the acetylene itself. Fire inspectors, insurance agents and safety professionals hate a gas that dangerous.

Is the flame of a match hotter than the flame of a liter?
No, a liter does however burn faster due to the fact that it is burning butane rather than wood.
Why LPG should not be used for Gas Cutting?
I can't see a reason why it shouldn't be used for cutting; it cuts better than acetylene does. What it should NOT be used for is gas welding, because it doesn't get hot enough.

Distinguish between an oxidising flame and a carburising flame in oxy- acetylene welding?
Basically, you need to look at the flame itself, if the tip of the nozzle is bluish/white, and long , then the flame is a carburising or reducing flame, it contains a high ratio of acetylene compared to oxygen, and will produce a cooler sooty flame. this can be used to make metals more malleable when working them, but the carbon is not helpful, and cannot be used for welding operations An oxidising flame is more pupleish/white and is far hotter, with more oxygen than acetylene, this flame is used in cutting, but will harden steel, making it brittle. in between the two is the neutral flame where welding operations are carried out.
