Ultrapulse Low Heat Resistance Welding
Ultrapulse solid state pulse resistance welding
is a process in which joints are produced electrically with little
heat since the weld is completed in milliseconds. In many cases, Ultrapulse
welding can join metals where no other process would be practical
Ultrapulse is resistance welding, but with little
or no melted nugget and with very little heat affect (1).
Absence of heat allows Quanta to weld pre hardened
tips to engine valves (2); finish-ground shafts to pistons, hubs or
gears (3); and studs, hard or soft, to thick or thin parts (4).
Brackets, nuts or studs can be welded to sheets
even if the opposite face of the sheet is painted or coated, without
damage to the coating (5).
