A friction stir welding tool holder is provided and includes: a tool holder cone, an end thereof is connected to the rotating spindle, a cone flow channel is formed therein, the cone flow channel has a valve, and the tool holder cone further has a tool locking ring, and the tool locking further has a tool accommodation groove axially arranged and a thermal sensing slot laterally arranged; a cutting tool, axially movable relative to the tool holder cone, where the cutting tool is arranged in the tool accommodation groove and has a machining end protruding from the tool accommodation groove; a torque transmission system, arranged between the tool holder cone and the cutting tool to transmit torque from the tool holder cone to the cutting tool; and a thermal sensor, inserted in the thermal sensing slot to sense a temperature of the cutting tool at any time.

Friction stir welding tool holder with thermal sensor

An additive manufacturing method includes: providing a metal substrate; pressing a plurality of first metal parts to weld the same on the metal substrate one by one using a welding unit through friction welding so as to form a first stacked layer laminated on the metal substrate; pressing a plurality of second metal parts to weld the same on the first stacked layer one by one using the welding unit through friction welding so as to form a second stacked layer laminated on the first stacked layer; and repeating formation of the second stacked layer until a required amount of the second stacked layers are additively laminated on the first stacked layer to obtain a final three-dimensional (3D) article.
