There are various forms of welding processes, however here we discuss the Shielded metal arc welding or stick welding procedure and machinery. The stick welding process uses an electrode that is considered consumable one that can be destroyed or wasted while it is used. An electric current flows from the power supply causing an electric arc between both the metal and the electrode holder. The electric arc is when a surge of electrons are caused to flow amongst two points and then it is divided by gas. The electrode coating or flux coat will melt away, releasing vapors creating a shielding gas and forming a slag, all designed to protect the weld area from the damage the air can cause. The air will damage the strength and quality of the weld area if not protected. The weld area is usually the material the being welded by the operator and usually the manufactured good or goods.

This stick welding procedure generally begins when the welding torch is swept across the source material in a sweeping motion or back and forth. Next, the welding torch will be pulled away by the welder, some describes these actions as similar to striking a match. Once you have the arc, they will began melting the material, causing the waste from the disintegrating electrode to drop small liquid drops. After the shielding gas has been initiated and the vapors start protecting the meld, the slag will rise and solidify. This hardened waste material will have to be chipped away to reveal the finished product. That is the basics of the stick welding procedure, one that is more detailed in steps compared to others and not considered, highly efficient.

The equipment needed to complete a stick welding project would include the welding power supply, electrode holder, a work clamp, and typically welding cables. The power supply used by a stick welder usually has a constant current output. It is with the stick welding process or while using a stick welder machine, the worker will hold the electrode torch, unlike other types of welding procedures.

There is a variety in types of electrodes that the worker would choose and it depends on the kind of weld material, position, and other needs for the project. There are three groups that most electrodes fall under and they are: fast-fill, fast-freeze, or fill-freeze. The fast-fill electrode group are meant to melt away very fast so that they can help to maximize the speed of the welding process. The fast-freeze electrode group is meant to supply filler metal that will coagulate quickly. The fill-freeze electrode group is called the intermediate group of stick welder electrodes.

Using these materials along with the stick welder, you can work in the Construction industry or Industrial and Repair industries. The popularity of the shielding metal arc welding machine and processes are said to be the most popular around the world. Having the ability to be able to be used in numerous positions I am sure has been a factor that has lead to its popularity overall.
