MULTI PORT CIRCULAR WELDING

A typical automobile fuel tank has a number of ports for inlet, outlet, fuel level indication, drain etc. We have developed an automatic multi-port welding SPM, which welds the ports to the fuel tank in a single setting. A well design fixture ensures accurate positioning, clamping rigidity and buckling-resistance effects, forced by the welding heat and clamping pressure. Multiple linear slide movements, assisted by an efficient PLC programming, provide accurate location to the welding torch to commence welding of each port to the tank in rapid succession. Rotary movement, in-built in the main fixture, provides smooth & accurate circular movement to the component at the exact locations. This is an ideal, low cost solution for medium volume component industries, engaged in the manufacture of sheet metal components, like fuel tanks, silencer etc.
