A robotic welding machine is a machine that is applied for the welding process, which is to fuse two pieces of metals together by melting the metals with the high heats that the wire feeder and the torch provided, and these processes are all conducted automatically.
The robotic welding machine is like a combination of several manual welding devices, as it is capable of performing various welding processes with the automatic control of the arms on one machine, which makes the manufacturers benefit from the enhanced efficiency of the welding processes and the productivity of the final products.
A welding machine utilizes the special properties of the metal materials, which melt when they come in contact with heat that is higher than how they can withstand, to fuse them as one assembly, which provides these metals with the firmest seal.
Due to the extraordinary feature of welding, which is to fuse two parts as one instead of stretching the materials as in the forming processes of the metals, this kind of machine is widely adopted in a variety of applications, such as the automobile or aircraft components production, the fabrication of thin sheet metals, or the attaching of ferrous and non-ferrous metals.
In the past, welding should be conducted by professional welders, who are specialized in the required techniques of each type of welding method and have the ability to promptly change different methods when it is necessary. However, recently, the newly invented robotic welding machine makes a difference in the welding work fields.
As the name implies, the robotic welding machine uses robotic arms to replace the hands of the manual operators, which reduces the required numbers of the operators, the time and efforts that might be spent on changing one welding method to another. In addition to the robotic arms that are capable of automatically controlling the welding processes, there are many other advantages that the robotic welding machine can provide, which would be discussed in the later paragraphs.
Now that there have already been well-trained professional welders, who are able to conduct different welding methods to achieve the requirements of the related applications, why use a robotic welding machine?
The answers may lie in some perspectives, which are to ensure the safety of the operators, to reduce the labor expenditure, and to improve the flexibility and quality of works.
● Ensure the safety of the operators
Since the welding processes would produce extremely high heat and bright lights on the working sites, which make the operators have to wear safety equipment during the processes.
While the safety equipment cannot ensure one hundred percent of the safety of the operators, which results in the need for a robotic welding machine. With this machine, the required operators who directly stand beside the working sites are eliminated, which can prevent hazardous circumstances from happening.
● Reduce the labor expenditure
As the requirement of operators reduces for each welding process, the labor expenditure would thus reduce as well, which saves quite a lot of costs for the manufacturers when it is necessary accordingly.
● Improve the flexibility and quality of works
In addition to the reduction of time and the required operators, when the manual operators are limited in some welding processes such as the break and off time of the operators, and the high heats and bright light that they are relatively less capable of withstanding, the robotic welding machine can deal with these problems perfectly, as the machine doesn’t have the limitation of the time and the working environments.
A robotic welding machine is mainly comprised of three parts, which are connected with the electrical components, including the control system, the operator interface, and the robot.
● Control system
During the operation of the robotic welding machine, the control system is not required to be operated, since it serves as the automatic control system, which contains the wires and other components that drive the motion of the robot arms and other parameters.
● Operator interface
The operator interface is a device that allows the operator to actuate and stop the operation of the robotic welding machine. Under the interface, there would be a coolant system that provides the coolant for the working sites when it is needed.
The robot has arms that serve like the combination of the operator’s hand and the clamping device, as the arms are able to hold the wire feeder and the torch, and clamp on the wires at the same time.
In short, there are several advantages that adopting a robotic welding machine can have. In addition to ensuring the safety issue, the improved efficiency and quality of works, this innovative design of the welding machine can help increase the productivity of the related products for a variety of applications, which benefit not only the manufacturers but also the customers who apply the products that are made by the robotic welding machine.
