Because soldering alloys all melt at temperatures much below 427C, 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. Most widely used are air-acetylene and air-propane torches.
Can you braze with just acetylene?
Air Acetylene set-ups offer a better and more economical alternative to brazing and soldering. Whereas oxy acetylene is almost twice the temperature and the 2700 degree heat takes a little longer in brazing applications it virtually eliminates the possibility of distorting or melting the metal.
Can you solder with a welding torch?
Torch Welding Can Be Done Even though lower-temperature blowtorches are better suited for brazing and soldering than actual welding, blowtorches that run on hotter fuel-air mixtures such as oxyacetylene can hold their own against more complicated welding techniques.
Can you silver solder with acetylene?
Use the oxy-acetylene only at the end to finally lift the joint temperature for silver soldering. Regretably your experience is not uncommon when oxy-acetylene is used. Finally – ensure that any future work is done in a well ventilated area.
Do you turn on oxygen or acetylene first?
OXY-ACETYLENE We recommend closing the oxygen valve first whenever turning off an oxy-fuel torch system especially when Acetylene is fuel.
Can you weld with only acetylene?
Gas welding involves the melting of a base metal and a filler metal, if used, by means of the flame produced at the tip of a welding torch. Generally, only oxy-acetylene (in specific cases oxy-hydrogen) is recommended for oxy-fuel welding.
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.
Does brazing require flux?
A fluxing agent (or a controlled atmosphere as found in furnace brazing) is required for all brazing and soldering applications. The purpose of the flux is to remove oxides from the base material and to prevent oxidation during the heating process, thus promoting the free flow of the brazing filler metal.
Is silver solder stronger than brazing?
Brazing rods look like straightened metal coat hangers, and like solder they become stronger as the percentage of silver they contain increases. The braze is what is melted by the torch to join two metals. For joining copper lines we usually use brazing rods that are made out of a copper-phosphorous combination.
Can you silver solder with a butane torch?
Be sure to get some flux, and be sure it’s specifically for use with silver solder. An ordinary household propane or butane torch will work, but even better is one of the new torches that burn MAPP gas. They burn much hotter than ordinary torches, which makes silver soldering go faster and easier.
Does solder stick to steel?
Now you can solder steel to pot metal at 350 degrees using a propane torch and Super Alloy 1 multi-metal solder rod and flux. To solder steel to pot metal, begin by removing all oxidation from both parts. This can be achieved using any type of abrasive material: sandpaper, Dremel tool, wire brush etc.
Can you solder an exhaust pipe?
Exhaust pipe is usually pretty nasty, unless it was brand new it would be very hard to solder. It also is a really good heat sink, it would take a propane torch. It might work if you are far enough away from the engine to not soften or melt the solder from heat.
Does silver solder stick to stainless steel?
Silver Solder can be used to join most common metals, including Mild Steel, Stainless Steel, Copper, Brass, Cast Iron and Dissimilar Metals.
