Welding Types and Welding Rods

Welding is the process of heating two pieces of metal so that they join and form a firm joint. To do this, one needs a high degree of ability and technology. There are different ways of welding; some need machinery and advanced technology, including lasers, beams, etc. Welders work with metals, alloys and materials.

Oxy-Acetylene Welding is a welding process which requires the use of a special welding torch to combine oxygen and acetylene gases and produce a fire of up to 6,300 degrees. This process is widely used to manufacture wrought iron gates and fences. This type of binding is normally used in industries that work with copper pipes, including brass wear plates and brass sticks.


Gas Cutting Using Oxy-Acetylene

The majority of the gas torches have a lever style valve that facilitates an extra burst of oxygen through the cutting torch to the job which has been heated to melting point. This shot of oxygen burns away the parent alloy with high force and rate, thus producing a narrow cut in the metal. In this way, welders can cut easily, either manually or by machines. Manual gas cutting can cut metals of 1/16 of an inch and up to two inches, whilst profile cutting can cut steel up to a thickness of four inches.

TIG welding

Tungsen welding or TIG welding uses a non-consumable tungsten electrode to create the weld. The weld area is protected by an inert shielding gas and a filler metal is used. This type of welding is used to thin sections of stainless steel and metals such as aluminum, copper and magnesium.

Plasma arc welding

In plasma arc welding, the electric arc is formed between an electrode and the work piece. The process is similar to TIG welding.

Laser Beam welding

Laser Beam welding is a meld technique where multiple pieces of metal are joined via the use of a laser. This type of welding is used in high volume applications, such as in the automotive industry.


Welding sticks of good quality should be obtained, so that the welding result is significantly better. Welding Rod is used to place additional metal to the weld. Hence, it needs to suit the metal. Welding wire and oxy-acetylene sticks are made of Norway steel. Choosing the right welding rod is essential as it will help to determine the success of a weld and the strength of a joint. If you choose the wrong pole, it can produce a meld that's either too hard or brittle.
