Can You Solder With Acetylene?

Can you solder with acetylene? Because soldering alloys all melt at temperatures much below 427

⁰

C,

to use an oxy- acetylene flame for a soldering operation is not only pointless, but difficult

, since that flame is so hot that overheating of the metal is hard to avoid.

Would you use propane or acetylene for soldering?

Difference in Gases

Acetylene burns over 1000°F hotter than propane

! Note that oxy acetylene combinations burn significantly hotter (5612°F) and should not be used for soldering copper as this is above coppers melting temperature (1984°F).

Can you solder copper with acetylene?

Soldering to join copper pipes may be done with an air acetylene

, air Mapp, or air propane torch.

Can you silver solder with acetylene?

Can you braze with just acetylene?

An air/acetylene system only requires the use of a single acetylene tank and gets oxygen from the atmosphere

. Since air contains only about 21% oxygen, it was difficult for older air/acetylene torches to reach the higher flame temperatures necessary for brazing.

Can you use acetylene without oxygen?

Decomposition is a chemical reaction whereby acetylene breaks down into its constituent elements, carbon and hydrogen. This reaction gives out a great deal of heat, which

can cause the gas to effectively ignite without the presence of air or oxygen

.

What is hotter propane or acetylene?

Acetylene releases almost 40% of its heat in the inner flame cone. Therefore, acetylene is better for cutting than propane. While temperature wise

acetylene is hotter than propane

the fact is that people are using propane for cutting incorrectly.

Is propane good for soldering?

When sweating or soldering copper pipe, we’ve been asked about using either propane or MAP gas. In truth,

both types of fuel will get the job done

.

How do you solder copper pipe with acetylene?

How hot does acetylene burn?

The heat is generated by the combustion of acetylene in oxygen, which gives a flame temperature of about

3100 °C

. This is lower than the temperature of an electric arc, and also produces a less concentrated heat.

What gas is used for silver soldering?

An ordinary household propane or butane torch will work, but even better is one of the new torches that burn

MAPP gas

. Most hardware stores have them. They burn much hotter than ordinary torches, which makes silver soldering go faster and easier.

Can you weld with Air acetylene?

An oxy-fuel gas welding process using an air-acetylene flame. This

seldom used process is used without the application of pressure

.

Which is stronger brazing or silver solder?

Soldering, in addition to having a lower processing temperature, typically results in a

lower-strength joint than a brazed joint

. For many applications, this is suitable and even desirable. The shear strength of brazed joints typically exceeds that of soldered joints by a factor of five.

Is acetylene hotter than MAPP gas?

Although

acetylene has a higher flame temperature (3160 °C, 5720 °F)

, MAPP has the advantage that it requires neither dilution nor special container fillers during transport, allowing a greater volume of fuel gas to be transported at the same given weight, and it is much safer in use.

Can you braze with a cutting torch?

What do you turn off first oxygen or acetylene?

OXY-ACETYLENE

We recommend closing the oxygen valve first whenever turning off an oxy-fuel torch system especially when Acetylene is fuel.

Can acetylene tank explode?

Acetylene is highly unstable.

High pressure or temperatures can result in decomposition that can result in fire or explosion

. Acetylene cylinders must never be transported or stored in a closed vehicle.

What happens when you lay an acetylene tank on its side?

Acetylene cylinders must not be placed on their sides, since

the acetone and binders will have dislodged

. The result may be formation of an acetylene “pocket” that is subject to polymerization and the possibility that liquid acetone will be released into the regulator.

Can you weld with propane torch?

I get asked “Can I weld with a Propane Torch”, a lot. Sadly, the simple answer is

NO, you need Oxygen and Acetylene to Fusion Weld

. A lot of companies are now offering Propylene as an alternative to Acetylene. Oxy/Propylene is a lot hotter than Oxy/Propane but you still can’t successfully weld with it.

How do you make acetylene gas at home?

What can be used instead of acetylene?

Propane and Apachi

: this is used in oxy-propane cutting and brazing. It is often used as an alternative to acetylene when high cutting speeds and efficiencies are not required. Oxy- propane is widely used for preheating components. Apachi is a method in which air produces own brand gas used as above.

Does propane burn cleaner than acetylene?

Acetylene will ignite at mixtures from 2.5 percent to 82 percent, while the range for propane is 2.1 percent to 9.5 percent. Based off of these numbers, it’s easy to argue that

propane is much safer to use than acetylene

.

What type of gas do plumbers use for soldering?

Use

MAPP gas

to speed up the job

MAPP gas torches burn hotter than propane, making them a better choice for modern solder. Five to 10 seconds of heating with a MAPP gas torch is all that’s required before you can feed solder into most 1/2- to 3/4-in. pipes and fittings.

What type of gas is used to solder copper pipe?

The torch needed for soldering copper can be

propane or MAPP gas (methylacetylene-propadiene propane)

. MAPP gas comes in a yellow tank and propane comes in a blue tank. MAPP gas, usually a bit more expensive, gets much hotter than propane, so heats the pipe faster.

Can you sweat copper with a butane torch?

A butane torch creates a flame that can reach a maximum temperature of about 2,500 degrees Fahrenheit. These high temperatures—coupled with butane’s long flames, which can reach up to 6 inches long—make these torches

capable of melting and soldering metals like copper and silver

.

Can you oxy acetylene weld copper?

5 Welding of Pure Copper Fusion

welding of copper with the oxy-acetylene torch is made difficult by two properties of copper

: its exceptionally high heat conductivity and its high coefficient of expansion.

Which solder is best for joining copper tubing?

Buy

lead-free solder

that’s designed for copper water pipes; you’ll find it in the plumbing section of the store. Solder with lead is still available, but the lead can leach into your water supply, so don’t use it.

What is the best way to solder copper pipes?

What is the hottest burning fuel?

Why does acetylene explode?

If a cylinder filled with compressed acetylene gas is exposed to a flashback, starts to warm up or vibrate, or if such a cylinder was involved in a fire, its contents may have begun to decompose

. This process can become self-sustaining causing the cylinder to explode, in some cases hours after the initiating event..

How do you extinguish acetylene fire?

Acetylene fires arising from wet calcium carbide inside a building shall be extinguished by

using dry-powder extinguishers or carbon dioxide

. No water or water-based foams shall be used in such situations.

Is a propane torch hot enough to silver solder?

Can you solder silver with propane?

Silver Solder & Braze are both products used with either an Oxy Acetylene Torch or

Oxy Propane Torch

.

Can you silver solder with a MAPP gas torch?

What metal can acetylene can work?

Propane also finds a place in production, for cutting very large sections. Oxy-acetylene can cut only

low- to medium-carbon steels and wrought iron

.

Is oxy-acetylene welding still used?

In recent decades, oxy acetylene welding has become obsolete. Our modern arc welders have more consistency and weld faster. However,

oxy acetylene cutting is still a commonly used process that is utilized by millions of welders every day

.
