There are many factors that you should consider before you choose the right electrode for welding. First you should consider the type of metals that are being used. You cannot universally use the same electrode for every metal you weld together.

Spot welding is a procedure in which two metal surfaces are melted jointly to form a weld. A couple of electrodes at the same time clamps the work pieces jointly and delivers the electrical current wanted to make the weld. The two electrodes focus the current onto a small spot, which is where the term "spot welding" comes from. Aluminum spot welding is becoming more common as aluminum replaces steel in many applications where weight is main, such as automobiles.

The shielded metal arc welding is also known as the manual metal arc welding. A consumable electrode is used in this process. The consumable electrode is coated in flux and is used to lay the weld.

Underwater welding is carried out mostly in ships. This is a process of welding where the process is carried out submerged in water. This is most commonly used in ships as the hull of the ship might require frequent repairs in the operation of the ship on the sea.

There are different types of electrodes that are used for the creation of electric arc. These electrodes should be of good quality if they are supposed to be of any use.

If they are not of good quality then they can easily spoil the whole process of welding. These metal electrodes consist of chemical wires that are covered in chemical coating. The arc of for welding is stabilized by the virtue of the structure of the electrode.

The Electrode:

You might have decided to purchase a welder for yourself. There are a couple of things that you should remember before you purchase your welder.

The types of welding equipment differ from model to model. However there are some standard parts that have to remain the same. The first such part is a torch.

Welding as you all know is one of the important procedures of any manufacturing unit. Welding needs a lot of knack and experience to do it effectively and perfectly. Only professionals with good experience will be able to do it efficiently. While welding we must make sure they wear proper safety gears in order to protect them from any danger. Welding safety equipments come in different designs and fitted for various purposes.

Welding is an important process in metal joining. Whether you are a professional in welding or it is just your hobby, there are certain safety procedures that you must ensure to follow while you are welding. The helmet is one of the most important elements in welding safety.
