Welding is a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion.
Robot welding is the use of mechanized programmable tools (robots), which completely automate a welding process by both performing the weld and handling the part. Robot welding is commonly used for resistance spot welding and arc welding in high production applications, such as the automotive industry.
Automotive, Electrical and Electronics
A basic robotic arc welding system is formed by two subsystems: the welding equipment delivering the energy from the welding power source to the work piece, and the robot providing relative positioning of the heat source and the work piece. Normally six-axis industrial robots comprising a three-axis lower arm and a three-axis wrist are used, since they enable the welding torch mounted at the wrist to achieve all the positions necessary for three-dimensional welding.
