Conventional Welding Automation

Automated welding machine 

Welding is an important process of industrial manufacturing. With the development of robotic technology and due to the demand of improving welding quality and flexibility, robotic welding system is used more and more in industrial community. The welding robot is in fact a kind of automated welding machine which needs to e programming a prior.
Welding automation has been classified as;
Simple mechanization (tractors and manipulators etc.
Special purpose systems (orbital welders etc.)
Dedicated automation (purpose designed)
Modular automation (component systems)
Programmable systems (robots. CNC machines etc.)
All of thaw systems remove elements of human mechanical effort from the welding operation, improve consistency and remove the operator from the welding hazards. Simple mechanization is often underutilized in the West but has he exploited very effectively in Japan. Dedicated automation is generally only justified for highs volume operations although it often completely removes the welding skill element during its operation. The most interesting trend is probably in welding robotics. Standard industrial robot systems have become more affordable and the user and peripherable interfaces have improved to give them greater flexibility. Generic off-line programming systems provide reduced production down time and the possibility of process simulation and optimization. On line position detection and seam tracking systems add to the potential consistency of the welded joint.
In spite of these advantages the following limitations are often quoted;
Inability to perform short butch or 'one-off' operations due to the high programming overhead.
Inability to achieve high accuracy on large workplaces
