Spot Welding Robots
Robotic spot welding, a type of resistance welding, is the most common welding application found in the manufacturing field. It joins thin metals together when the metals resist the electrical current.
Automatic welding imposes specific demands on resistance welding equipment. Often, equipment must be specially designed and welding procedures developed to meet robot welding requirements.
The spot welding robot is the most imortant component of a robotized spotwelding installation. Welding robots are available in various sizes, rated by payload capacity and reach. Robots are also classified by the number of axes. A spot welding gun applies approriate pressure and current to the sheets to be welded. There are different types of welding guns, used for different applications, available. An automatic weld-timer initiates and times the duration of current.
During the resistance welding process the welding electrodes are exposed to severe heat and pressure. In time, these factors begin to deform (mushroom) the electrodes. To restore the shape of the electrodes, an automatic tip-dresser is used.
One problem when welding with robots is that the cables and hoses used for current and air etc. tend to limit the capacity of movement of the robot wrist. A solution to this problem is the swivel, which permits passage of compressed air, cooling water, electric current and signals within a single rotating unit.The swivel unit also enables off-line programming as all cables and hoses can be routed along defined paths of the robot arm.
While it is commonly used in the automotive industry to join sheet metal frames together, the spot welding application has a variety of project uses.
Automating spot welding is quick, easy and a great economic solution. These robots offer various kinds of floor space savings, which is why so many automotive manufacturing companies have incorporated to this kind of robot into their plant.
Automated spot welding robot systems will provide your company with consistent welds and increase the quality of your product.
We can also integrate new and used robots into spot welding workcell configurations. With successful integrations throughout China, Mexico and Canada, ABK Machinery has built a reputation for excellent workmanship and customer service. Every system is constructed to match client specifications.
