| INDUCTION WELDING |
That welding process in which weld is produced by the the heat obtained from the resistance of the weldment to flow of an an induced electrical current is known as induction welding.
process :
In opreation a high current is induced with both edges of the work
close to where weld is to be made .Heating to welding temperature is
extremely rapid and the joint is completed by pressure rolls or
contacts.A form of induction welding known as high-frequency welding is
similar except that the current is supplied to the conductor being
welded by direct contact.High -frequency current flow near the surface
of the metal and as heating is almost instantaneous,there as chance of
hamful oxides high frequency welding.
Application
; It is a high -speed process and is best suited for high production
use. Welding speed ranges from 60 m/mt to 300 m/mt. It is now,being used
for most metals ,e.g,copper and copper alloys,nickel ,zirconium and
many types of steels.
