Automated Welding Robotic Welding Applications

Robotic Welding Automation

Robotic welding is the process of using programmable robots to automate the welding process of materials. Not only does it increase production it reduces weld times, saves on weld filler and provides accurate results. There are various types of robotic welding.

Laser Beam Welding

This is the precise process of using either a continuous or a pulse laser beam to create welds. Since it is precise, the hot zone does not get very large during welding giving very defined welds with the least chance of error. A robot laser welding system consists of a servo-controlled, multi-axis mechanical arm, with a laser cutting head mounted to the face plate of the robot arm. The cutting head has focusing optics for the laser light and an integral height control mechanism.

Plasma Arc Welding

Plasma Arc Welding also known as PAW welding is when the joining of metals takes place by heating with a constricted arc between the work piece and an electrode or the constricting nozzle and the electrode. It is similar to gas tungsten arc welding since the arc is formed between a pointed tungsten electrode and the work piece. It allows for the Keyhole Effect (complete single-pass penetration) and smaller heat zones allowing for accurate welds and plasma welding robots allow more flexibility with easy adjustments to the velocity and temperatures at which the weld is formed.

Resistance Spot Welding

This process also known as Spot Welding uses two different welding heads on either side of two pieces of metal causing the surfaces between the two pieces of metal to fuse to a weld nugget. The welding heat is generated by an electrical current. No electrical arc is struck on the base material. Instead, the current ‘feeds back’ creating excessive resistance, friction, and heat. Spot welding is quick and easy to perform and simple to automate in a manufacturing process.
