Description

technical field [0001] The invention relates to a friction welding physical simulation test device, in particular to an inertia friction welding physical simulation device for simulating the plastic metal flow behavior of an inertia friction welding joint and monitoring the temperature field of the butt joint. Background technique [0002] Inertial friction welding technology is a solid phase connection technology invented by the American Tracked Vehicle Company in 1962. Inertial friction welding is a type of friction welding in which the energy required for welding is mainly provided by the rotational kinetic energy stored on the welding machine. In inertial welding, one of the workpieces is attached to a flywheel while the other does not rotate. Accelerate the flywheel to a predetermined speed to store the required energy, then disengage the drive motor and use the upsetting force to press the workpieces down and rub against each other. As the speed of the flywheel decre...

Problems solved by technology

The former cannot reflect the temperature of the weld area in real time due to the lagging reaction of the thermocouple; the latter hinders the real-time monitoring of the surface temperature of the weld by the infrared thermometer due to the flash and spatter of the welding process, and cannot monitor the temperature field inside the weld. to observe the changes

According to the retrieval of relevant literature, there is no report involving the inertial friction welding physical simulation test device. Therefore, a physical simulation test device with simple process and convenient operation for studying the plastic metal flow behavior of the inertial friction welding joint and the distribution of the weld temperature field is sought. become an urgent problem to be solved in this field
