For generations, humans have used various methods to heat metal for welding. However, today, robots have realized the automation of the welding process. The development of various welding robots has accelerated in the industrial world, because welding robots have many tools that are not available in manual tools. 

Before we delve into the various types of welding robots, it is necessary to understand that one welding robot can be configured on two main welding versions. For linear welding robots, the machine's arms are configured to move in three directions, while the robots configured by the joint version can move through more planes.

After the robot operator uses the teach pendant to configure the controller, the operator starts the welding process by pressing a button on the service box. The tools of the robot arm heat the metal to melt it before joining the parts together. The wire feeder supplies welding wire and welding torch to the arm as needed. After the robot completes a part, it pushes the cutting torch to the cleaner for cleaning to remove any metal splashes on the robot arm to prevent them from solidifying in place.

In the two versions of the robot configuration, the filler wire is transferred to the robot via a wire feeder. After using a high-temperature welding gun to melt the metal, the molten metal is placed in the arm of the welding robot for the welding process. 

This automated welding method is superior to the traditional welding process because it is safer. Welding robots replace labor affected by the high temperatures required to melt metal. Nevertheless, a certified expert is still required to supervise the welding robot in case the machine malfunctions.

The development of special robots for arc welding has also increased the use of robots in welding because they are smaller, more cost-effective, flexible, and occupy less operating space. In addition to increasing productivity, the use of welding robots also improves the quality of products produced and reduces operating costs.  

If you are purchasing a welding robot for your company for the first time, it may not be easy to find the best welding equipment. Today's market offers a range of options, leaving you confused as to which machine is best for your company's operations. 

The first step in determining the best robot for your company is to determine the welding process you need. Robot welding includes:

Each type of these processes has its advantages and disadvantages in specific scenarios. Therefore, you need to review each process carefully to determine the process that best suits your needs. 

The second step in determining the best robot for your company is to consider some equipment. You need to determine the automation consumables and automation peripherals that will best help you increase productivity and return on investment. It is best to consider the manufacturing software used by the robot, remote support capabilities, and performance analysis. Because these also play an important role in the difference between average productivity and peak productivity. 

In order to improve your company's competitiveness in the global market, you need to invest in the right welding robot. The best way is to choose a robot with a proper welding system and the latest software development. Let us now narrow down the options to help you take a closer look at each device and process. 

This is an arc welding robot with 6 to 7 axes. According to its size, its weight is between two to thirty kilograms. Its acceleration and speed capabilities are up to 25 m/s2 and 5 m/s, respectively. Gantry welding robots also have repeatability up to 0.05 mm and digital and analog IO.

This type of robot is very suitable for connecting current-resistant metals. They are commonly used to connect metal frames in cars. There are also many kinds of resistance welding for this type of welding. 

This type of robot is very suitable for economical welding and heat treatment projects. Electric current passes between the metal sheets, and then the metal sheets are connected to form a hot pool. 

These robots are ideal for performing processes that require high precision. 

These robots are ideal for fast and straightforward processes that do not require too much attention to detail. They have a direct and relatively fast high deposition rate. Due to the low accuracy, this robot welding process requires the continuous feeding of the welding wire into the welding nozzle, so that the surface area of ​​the molten welding wire or metal is larger. 

This robot is very suitable for welding operations where it is difficult to reach the welding position. The laser light is transmitted through fiber optic cables. This type of robot is also used for high-volume applications that require precision, such as biomedical companies, the jewelry industry, and automotive parts that require precision applications. 

The robots are ideal for processes that generate extreme temperatures during welding, as they provide flexibility through temperature and speed adjustments. 

There are different types of welding robots. Finding the right welding process for your organization requires you to determine the welding process your company needs and consider the features that will enable you to achieve your goals and maximize production at the lowest cost.
