English term or phrase:4 ball weld load
This is a test method, in which three steel balls are clamped together and covered with lubricant, while a fourth steel ball is pressed into the cavity formed by the three balls. The temperature is brought to 35°C, and the ball is rotated at 1760 RPM. A series of tests of 10 seconds duration are made at increasing loads until welding occurs.
