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 skill and technology. There are different ways of welding; some require machinery and advanced technology, including lasers, beams, etc. Welders work with metals, alloys and materials.
Oxy-Acetylene Welding is a welding process that requires the use of a special welding torch to mix oxygen and acetylene gases and produce a small flame 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 rods.
Gas Cutting Using Oxy-Acetylene
Most of the gas torches have a lever style valve that facilitates an extra burst of oxygen through the cutting torch to the work that has been heated to melting point. This shot of oxygen burns away the parent metal with high force and speed, thus producing a small narrow cut in the metal. 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, while profile cutting can cut steel up to a thickness of four inches.
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 normally used. This type of welding is usually used to thin sections of stainless steel and metals like 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 through the use of a laser. This type of welding is often used in high volume applications, such as in the automotive industry.
Welding rods of good quality should be bought, so that the welding result is better. Welding rods are used to place additional metal to the weld. Hence, it needs to suit the parental metal. Welding wire and oxy-acetylene rods are mostly made of Norway steel. Choosing the right welding rod is important as it helps to determine the success of a weld and the strength of a joint. If you choose the wrong rod, it can produce a meld that is either too hard or brittle.
