Single Sided Spot Welder

Single sided spot welder is one kind of spot welder that is designed with single sided features for the welding process. In the welding industry, spot welding is a type of resistance welding process that is used mainly for welding two or more metal sheets together by applying pressure and heat to the weld area. 

What Is a Single Sided Spot Welder?

Single sided spot welder is one kind of spot welder that is designed with single sided features for the welding process. In the welding industry, spot welding is a type of resistance welding process that is used mainly for welding two or more metal sheets together by applying pressure and heat to the weld area. 

This type of welding contains a certain specification of its own, and it typically delivers current for 0.1 seconds or less, so the current must be extremely high, and spot-welding machines typically deliver 150 amps per phase draw on a 440-volt system. In fact, for onsite operators, the welding guns are normally difficult to handle for operators, because that can be very heavy and often require great strength, which makes spot welding very dangerous in the manufacturing site. 


How Do Single Sided Spot Welders Work?

During the process, high amounts of heat and current are involved in the spot welding process, and the welder is constantly around hazardous sparks and welding fumes. As a result, workers of spot welders shall be very careful to the equipment as well as the surrounding environment. 

Besides, there are a broad series of welding machines within the welding machine inventory, and this type of machines has been developed for a long time with their own kinds across very wide applications in the industry, such as flash butt welding machines, grating welding machines, and many other types of welding machines in the market.

Welding Methods for Single Sided Spot Welder


● Projection Welding Method 

In regard to the spot welding machine, here we introduce the projection welding method at the very first since this one belongs to the spot welding machine and is very popular in the industrial sector. 

Today, projection welding machines are a modification of spot welding machines. During the projection welding process, the weld is localized by means of projections on one or both of the workpieces to be joined. The heat is concentrated at the projections, which permits the welding of heavier sections of welds. The projections can also serve as a means of positioning tools for the workpieces. Conventionally, projection welding is often used to weld studs, nuts, and other threaded machine parts to metal plates and is productive in these processing times. 

In the welding sector, a resistance spot welding machine is welding machinery by the process in which contacting points of metal workpieces are joined by the heat obtained from resistance to the electric current. So, it is considered a subset of electric resistance welding. During the process, workpieces are clamped together under pressure exerted by the electrodes. Usually, the sheets are within a certain range, ranging from 0.5 to 3 mm thickness as planned by the engineers.


● Seam Welding Method 

In the metal welding field, a resistance seam welding machine is a welding machine in which the welding process produces a weld at the faying surfaces of two similar metals. During the process, the seam may be a butt joint and is an automated procedure. 

This method is different from flash welding in that flash welding welds the entire joint at once while seam welding forms the weld progressively and starts at one end. Flash butt welding is a very useful welding method, and the flash butt welding machine is an electrical resistance welding process designed on a welding machine that is utilized for joining components, in which the energy transfer is offered primarily by the resistance heat. 

The components are positioned end to end across the full joint areas. A range of section sizes and complex shapes can be con-joined through this machine. During the process, the parts are clamped and brought together slowly while a flashing voltage is applied. Though the process can be manually achieved, most welding machines nowadays are automatic for better controlled accuracy standard. 


● Automatic Welding

When it comes to welding, which by definition, is a fabrication process that joins metal materials by using high heat to melt the parts together and allowing them to cool causing fusion. Welding is distinct from lower temperature metal-joining techniques such as soldering and brazing. In addition to melting the base metal, a filler material is typically added to the joint to form a pool of molten material that cools to form a joint that is based on weld configuration can be stronger.

In the automation process, the automatic welding machine is controlled by computer programs to conduct the welding procedures. In this way, operators are free from manual operation in certain specific details and processes, rendering a more stable working process with less reliance on manual force. As a result, this reduces the cost of human workers and the participation of manual operation. It is anticipated that with automation to be advanced in the future, such models of welding processes can be improved much and gain more productivity.
