Electric arc welding is a method of melting metal parts by using an electric arc to generate intense heat that causes the metal to melt at the junction between two workpieces and fuse together. An electric arc is created by the passage of an electric current through the electrode and the workpiece. The molten metal solidifies after cooling, resulting in a strong bond between the metal parts.
Arc welding is a welding process that uses an electric arc to generate heat and melt the metal, which is then cooled to form a solid joint. It is a popular welding method used in many industries due to its high welding speed, versatility and cost-effectiveness.
Arc welding robotics is a manufacturing process that uses programmable mechanized tools for a fully automated welding process where both welding and part handling are performed by the robot.
Robotic arc welding has become increasingly popular due to its largely human-independent process. The most common robotic welding devices consist of two main components:
A mechanical unit performs manipulations on materials or parts to create a component or product.
The controller is considered the “brain” of the unit because it is what causes the arms of the unit to move according to the design implemented in the system.
Finally, the many benefits of robotic welding have enabled many employers to increase accuracy, repeatability and throughput.
A basic robotic arc welding system consists of two subsystems: the welding equipment that delivers energy from the welding power source to the workpiece, and the robot that provides the relative position of the heat source and the workpiece. Commonly used six-axis industrial robots include a three-axis arm and a three-axis wrist, as the wrist-mounted welding torch enables it to achieve all positions required for three-dimensional welding. Traditionally, general industrial robots have been used that carry arc welding torches as end effectors. Many robot manufacturers have recently developed arc welding robots that are smaller and cheaper. This reduction in capital requirements has increased the sale of robotic welding systems. Another recent development in welding robotics is the introduction of seven-axis robots, which have an additional axis in the lower arm that provides greater flexibility and saves floor space.
What are the advantages of robotic welding over manual welding?
Manual welding can be a very dangerous operation, which makes robotic welding one of the most practical methods for suppliers. Not only does it contribute to a safer work environment, but robotic welding has significant advantages over manual welding in improving quality, maximizing efficiency, and reducing labor costs. Here are some other benefits:
Faster and more consistent cycle times. Robotic welding systems can operate 24 hours a day, allowing for greater productivity and throughput.
Higher quality and higher volume. High Volume Welding Systems can produce high quality welds with speed, accuracy and efficiency to produce high volumes of diverse parts.
Fewer interruptions Robotic welding systems allow for fewer interruptions than human-led production. It also creates a safer work environment and solves potential labor shortages.
Finally, manual welding can have many hidden costs and require the human welder to undergo training that takes time, skill and focus to master. In contrast, robotic welding produces parts in a short period of time with high precision and costs less.
