Spot welding one of the most popular and oldest methods in the welding process. Also, it is one of the electric resistance welding methods for joining two metal sheets. The best part about the spot welding is that it can join metals that are 3 mm in thickness. The entire amount of heat needed to carry on with the process depends upon the metal. Though it is used in several industries being very particular it serves sheet steel vehicle bodies.
Pros:
Very quick since the heat generated is extreme the output is achieved very quickly and thereby it lend out a hand for maximum capacity.
Cost-effective, since robotic use can be integrated during the process the result brought out is effective and cheap. High pressurizing system helps out in the reduction of utility bills.
Cons:
Because of the high thermal conductivity it turns out to be an intricate process to weld silver and copper.
It occupies larger space also requires someone to hold the product. Leave away more Electrode stubs.

Stud welding is a form of spot welding. Here all the energy is concentrated into one spot to create a weld. The specialty of a stud welding is that a bolt is especially created for the purpose of welding and a nut is fed into the bolt to form the weld. The bolts are very often fed into the automatic spot welder. The weld nuts will have a flange that will meet with the bolt to form a weld. The stud welding is also known as a stud arc welding. This welding type joins a stud and a bolt together for the purpose of welding. A flux called ferrule is used in stud welding. This flux will concentrate the heat that is generated so that the welding can be carried out. These form very effective welds and make sure that sturdy bonds are formed. The most common applications would be shipbuilding bridges are other huge steel structures.

Spot welding is a very common form of resistance welding. In this welding process, sheet metals that are up to 3mm thick can be joined. The reason why this welding process is very effective is because of the concentrated area of welding that is taken in when the welding process happens. This method makes efficient use of energy and does not waste energy by making long welds. Welding is done in spots, as per the name, which forms hard thick joints which are very effective in holding the two metals together. This method of welding makes it easy to work with limited workspace and also increases the production rate. There are no filler elements required in this form of welding and the whole process can be easily automated. It should be remembered that the weld strength of this process is comparatively lesser than the other welding methods and hence this method is only suitable in certain applications.

The resistance welding method is known to create less pollution and it is a very effective means of welding. Under this method, the most commonly used welding process is the stop welding.
The method is normally used for welding two metal pieces together that are over 3mm thick. This process does not require a filler material, nor is an arc created by this process. This process is known for its effective energy consumption and minimum work piece distortion.
Also high rate of production can be carried out as the process is simple and semi automatic. However you should remember that the welding strength for this kind of process is low. Therefore they are used for only limited number of application.
This type of welding can be used for stainless steel work pieces as well as steel work pieces. They are used for industrial as well as domestic applications and are very effective in quick jobs.

Spot welding is a process to join two metal surfaces together. This process makes use of the heat that is generated from the resistance to the electric current that flows through the metal pieces. The two work pieces are held together with the help of electrodes. These electrodes are most commonly copper alloy electrodes. The copper alloy electrodes are used to concentrate all the electric current onto a single spot which creates a weld.
The weld is formed by the melting of the spot where a large amount of current is concentrated upon. The reason why spot wielding is favored is because a lot of current is concentrated on a single spot which creates a quick weld. A relatively less amount of time is taken for the joining of the two metals. The permits the welding of the two metals without heating up the rest of the sheet excessively.
The amount of energy or heat that is delivered to the spot is determined by the duration of the weld as well as the amplitude of the current that is used. A stop weld will increase the hardness of the material. The basic components of a spot welding machine would include a welding transformer, welding electrodes, capacitor banks, and switches.

Spot welding can be termed as a procedure in which the contacting metal facades are combined together by the temperature produced from resistance to thrilling current stream. Generally, the method utilizes 2 copper alloy electrodes to deliberate welding energy into a tiny stain and at the same time compact the sheets together. The amount of electrical energy is selected to counterpart the sheet’s substance properties, its size and kind of electrodes.
Keep in mind that if you use little amount of energy then you will not be able to melt metals otherwise get a poor joint. On the other hand if you apply excess of energy then it will over dissolve metal and make a mess than a joint. So it is necessary to use required amount of energy. Electrodes that are utilized in spot welding can vary significantly with diverse applications: When it comes to high heat applications, radius style electrodes are utilized. Condensed tip electrodes are used for high pressure, whereas eccentric electrodes used for welding corners. Offset peculiar tips used for reaching into corners and minute spaces.

Spot welding is one of the very unique techniques of welding that people have used. This welding is performed by combining heat with pressure and time. Further to this, the process is carried on by using a current flow through the confrontation of the material so that it localizes heat in one spot. The amount of time taken by the current to flow into the joints is based on the thickness and the type of metal that is going to be welded. The main advantage of this type of welding is that the entire sheet does not get heated up during the process as it takes very few milliseconds for lot of energy to flow to the spot to be welded.
Spot welding is also known as resistance spot welding as it is one of the few welding procedure which generates fewer amounts of arc rays and fumes. As tongs and linkages are used, welders have to protect themselves for their own safety from the equipments that are kept around. Hence it is advisable to wear safety equipment before performing the welding activity.
When a welder performs spot welding he has to make sure that the current is flowing through the tip of the metals which are going to be joined. This process of welding is unique as you observe that the welded bead is formed inside the surface of base metal. This process of welding is different from a TIG or MIG spot welding.

There are many kinds of welding such as Mig welder, Tig welder, Arc welder and many others. You can also find few resistances welding such as spot welding. Spot welding is mostly used for welding sheet metal fabricators. It is a process of touching the surface of metals by heat which is joined with another metal where the heat is generated from electric flow to resistance.
These welding are one of the oldest and were known as projection welding. These are very useful while welding for thin foils. These are energy efficient and also can weld in high speed. This welding equipment has an ease of automation and are very easy to handle. These are used for many kinds of applicators such as automobile industry, orthodontist and many other industries. You can spot weld the aluminum alloy with the use of powerful welding transformer. This is very useful for welding the sheet metal for cars and can weld automatic with the help of robot. These are also utilized for joining the cells of batteries with nickel straps. The battery might get hot while soldering but nothing will happen if you use spot welding.
