Seam welding is one of the basic processes in resistance
welding.The continuous seam is formed by a lot of overlapped welding
spors.Two lapped welding pieces are forced between two
electrodes(welding wheels).After squeezing,wheels rotate and the welding
pieces are gone forward.The welding current may be switched on
continuously or intermittently.
By means of using the intermittent welding,the high quality welding seam
can be got,but it should be controlled the welding processing with the
help of control cabinet.
Seam welding model FN1-150-1/2 are used respectively for transversal and
longitudinal welding of non galvanized mild steel of alloy steel plates
equipped with control cabinet model KF4-500-1. http://www.autoweldingmachine.com
