Auto welding: what is it?

Automatic welding, or robotic welding, uses robots programmed to perform welding sequences with precision and without human error. The technology has improved with wire spools and advanced computer programming. It eliminates the need for costly ventilation and respirator systems required for human welders, and reduces repair work due to human error.

Automatic welding is also called robotic welding. Advances in technology have allowed robots to take up skilled trading positions in manufacturing plants around the world. When a product that has traveled down an assembly line stops between welding robots, the robots begin automatic welding sequences that have been programmed into a control system. The advantage of automatic welding is a perfect weld every time without human errors.

As the development of the wire welding machine improved, the design of the automatic welding robots also improved. The wire spool allows for hours of welding without requiring a spool change. The computer programming that controls the automatic soldering stations is so advanced that any problems it finds can be corrected without human intervention. By using automated welding robots, a manufacturer is able to avoid costly ventilation and respirator systems required for welding personnel.

In the early years of production, a human welder was required to perform the welding operation. Welders used replaceable welding rods that had to be changed when they burned out. The fumes and toxic gases produced by welding began to create health problems directly related to welding. This required the use of welding respirators which would filter out the toxins. The early form of the respirator was uncomfortable and hot, requiring frequent breaks to avoid exhaustion on the wearer’s part.

For many years it was thought that men could do a better job on an assembly line than machines. As machines began to improve and labor costs increased, components such as automatic welding robots began to dispel myths about unreliability and robots. The automotive industry was one of the first to fully understand the automatic welding robot. A batch of robots was soon tasked with completing all of the welding sequences needed to create an automobile. Repair and rework requirements were reduced and soon there was no longer a need to man a repair crew for the assembly line.

Before the introduction of automatic welding robots, a repair team was needed to fix the mistakes made by human welders. The machines proved proficient at completing correct welds with correct penetration and proper start and end points. Unlike its human counterpart, the robot welder is able to hit the start mark exactly and complete a flawless weld at the correct speed and temperature nearly every time. The ability to eliminate repair work due to human error helps the manufacturer reduce project costs.
