    摘要: Methods and systems for providing a cold plate assembly include providing a base and a cover. The cover can be fixedly coupled to the base. Each of the base and the cover can include spaced internal ribs, which can form flow paths when the base and cover are fixedly coupled together. The internal ribs of the base and the cover can have spaced tabs that can be fixedly coupled to the other of the base or the cover. The base and the cover may also include spaced external or outer sacrificial ribs.

    摘要: A friction stir spot welder includes: a pin; a shoulder; a rotary driver; a tool driver; and circuitry that performs an operation of driving the rotary driver and the tool driver such that the pin and the shoulder press a workpiece by a first pressing force while rotating at a first rotational frequency, and after the operation, performs an operation of driving the rotary driver and the tool driver such that a tip of the shoulder in a rotating state is pressed in to a first position. The first position is a position corresponding to 46% or more of a thickness of the workpiece from a front surface of the workpiece. A press-in speed of the shoulder until the shoulder reaches the first position is a constant speed.
