They are used for repairing things made of aluminum. What is needed is a heat source from gas such as propane gas, mapp gas or oxy-acetylene gas. This method makes for stronger welds than conventional Tig welding. It works on aluminum and cast aluminum, pot metal, copper, magnesium and white or porous metals. One of the main benefits of using aluminum arc brazing is that it can be used to weld and repair metal structures and things that are difficult to work on with more conventional welding methods. This includes corroded parts and also areas that have come in contact with oil and fat that make the area difficult to work on using the older methods of aluminum welding rods. The weld produced is stronger and the work quicker using aluminum arc brazing.

What type of electrodes are used in MMA arc welding?
A huge variety of electrodes are available. MMA, SMAW, STICK WELDING are all the same process. Electrodes are produced to weld almost all metal and metal alloys. From steel to cast iron to aluminum to stainless steel to monels to ???? If it can be STICK WELDED an Electrode is made to do the job.
How is magnesium welded with out it being ignited?
Some methods are used: - electron beam welding - laser beam welding - gas wolfram arc welding - gas metal arc welding - resistence welding - brazing
When and why you use oxy acetylene instead of arc welding?
Primarily when brazing cast iron. Nickel rods are available to arc weld cast iron but in most cases it has to be preheated and it takes experience to prevent cracking. Using oxy-acet provides a means to preheat, maintain the temperature, and braze. Welding, brazing, and silver soldering with oxy-acet have become lost arts. Most common metals can be welded with this process including steel and aluminum.
What is manual arc welding?
Everybody used to call it "stick welding". MMAW Manual Metal Arc Welding is the correct nomenclature. The "sticks" are electrodes held in an electrode holder connected to a power supply. Establish an arc between the end of the electrode and the metal and move across the joint. As you weld the electrode is consumed. Discard the "stub", insert a new electrode and continue.
Is there types of electrodes in Shielded Metal Arc Welding?
Probably more than there are types of metal. There are many electrodes manufactured just for welding steel and for welding ON steel. Some electrodes are made to weld steel and other metals (multi-purpose). Some electrodes are designed to protect steel from chemicals and corrosive elements and are used to CLAD or OVERLAY or BUTTER. Steel, stainless steel and some other metals are manufactured with different alloys and electrodes are made to match these. Some electrodes are made to join dissimilar metals, say steel to stainless steel or Monel. It is very important to use the correct electrode for the application at hand.
What are welding electrodes used for?
Welding Electrorodes or Welding Rods are used in arc welding. Arc welding is a special type of welding which uses a welding power supply to create an electric arc between the base material (e.g. steel) and the electrode. The Welding Ectrorodes can be used for all weldable aluminum and mild steel.
What is the primary use of carbon and graphite electrodes?
The primary use of carbon and graphite electrodes is in the manufacturing of steel through electric arc furnace (EAF) process. These electrodes are used to conduct electricity and generate the high temperatures needed to melt the raw materials for steel production. Additionally, they are also used in the production of aluminum, silicon, and other metals.
What is electrical arc?
Electrical arc is the discharge of charges in the air-gap between two electrodes. When the electrodes are excited the air between the electrodes get ionized and star conducting which causes cotinuous spark between them called arc.

A huge variety of electrodes are available. MMA, SMAW, STICK WELDING are all the same process. Electrodes are produced to weld almost all metal and metal alloys. From steel to cast iron to aluminum to stainless steel to monels to ???? If it can be STICK WELDED an Electrode is made to do the job.
How does a Carbon Arc Torch work?
A Carbon Arc Torch works by creating an electrical arc between two carbon electrodes. When current flows between the two electrodes, it ionizes the surrounding air, creating a high-temperature arc of light and heat. This intense heat can be used for welding, cutting, or melting metals.
What is a carbon arc lamp?
An arc lamp is a lamp that produces light by an electric arc. The carbon arc light, which consists of an arc between carbon electrodes in air, invented by Humphry Davy in the early 1800s, was the first practical electric light.
How is magnesium welded with out it being ignited?
Some methods are used: - electron beam welding - laser beam welding - gas wolfram arc welding - gas metal arc welding - resistence welding - brazing

What type of tungsten is used for welding aluminium?
Pure tungsten is commonly used for welding aluminum due to its ability to provide a stable arc and good heat resistance. However, ceriated tungsten is also a popular choice as it offers better arc stability and works well at lower amperages. Ultimately, the choice of tungsten type may depend on the specific welding application and personal preference.
When and why you use oxy acetylene instead of arc welding?
Primarily when brazing cast iron. Nickel rods are available to arc weld cast iron but in most cases it has to be preheated and it takes experience to prevent cracking. Using oxy-acet provides a means to preheat, maintain the temperature, and braze. Welding, brazing, and silver soldering with oxy-acet have become lost arts. Most common metals can be welded with this process including steel and aluminum.
Why is heat transfer efficiency greater in arc welding processes that utilize consumable electrodes?
Because generally the tool used for arc generation (for example the tungsten electrode in GTAW) will absorb some of the heat.
