The first advanced fan was produced using traditional methods, but future blisk fans will be made using translational friction welding with the goal of reducing manufacturing costs.

"' Spin welding "'is a friction welding technique used on thermoplastic materials, in which the parts to be welded are heated by friction.

In this position he was responsible for the development of new equipment, primarily linear friction welding machines, but also friction stir welding machines and rotary friction welding machines.

15.
In friction welding, the two parts to be assembled are rubbed together at a lower frequency ( typically 100 300 Hz ) and higher amplitude ( typically ) than ultrasonic welding.
16.
Further testing of these methods was done in the following decades, and today researchers continue to develop methods for using other welding processes in space, such as laser beam welding, resistance welding, and friction welding.
17.
In 1956, KUKA manufactured the first automatic welding system for refrigerators & washing machines and supplied the first multi-spot welding line to Volkswagen AG . Ten years later, the first friction welding machine went into production.
18.
The process and contact can be compared to cold welding or friction welding, because cold welding is not truly cold and the fusing points exhibit an increase in temperature and energy density derived from applied pressure and plastic deformation in the contact zone.
19.
After obtaining a qualification as a Class 1 welder, in 1961 he joined the British Welding Research Association ( which subsequently became The Welding Institute and then TWI Ltd ), where he conducted research on the fatigue strength of structural steel and on friction welding.
20.
He was a project leader in the friction and forge process group at TWI in Cambridge, UK . He conducted high level research in friction welding, linear friction welding and related processes for international and national aerospace companies, such as Boeing ( US ), Rolls Royce ( UK ) and Embraer ( Brazil ).
