A seam ripping assembly for use in preparing a coiled tubing operation in a production well, such as, for example, in the oil and gas industry. More particularly, the present invention pertains to a method and apparatus for seam dressing that can be used to efficiently remove a weld seam along an inner diameter on a section of coiled tubing, thereby allowing a coil connector to then be able to attach to an end of said section of coiled tubing.

The invention discloses a laser assisted micromachining system. The laser assisted micromachining system includes a working sliding, a tool module, a laser module, and a temperature control module for the processing of a workpiece. The laser module is disposed in the working slide and moves with the working slide in three-dimensional space. The temperature control module includes a temperature sensor, a cooler, a controller and a coolant, which detects the real-time temperature value of the cooler. The cooler is located in the working slide and supports the tool module. The controller controls the working state of the cooler according to the temperature feedback. Control signal induced by the temperature indicator, and the working state of the cooler are controlled by the controller. The coolant is used to control the temperature distribution of the cooler in the setting range. At the same time, the invention also provides a temperature control method for the laser assisted micro machining system.

The present invention discloses a laser shock forging and laser cutting composite additive manufacturing device and method. The device forms two different light guide systems by splitting an output laser beam of a laser device into two laser beams through a beam splitter system. The first light guide system splits a laser beam into a third laser beam and a fourth laser beam which are respectively applied to laser 3D (3-Dimensional) printing and laser cutting. The second laser beam is applied to laser shock forging. A three dimensional model is built according to individual design requirements of a part. Layer-by-layer slicing treatment is performed to acquire slice contour information, so as to determine a layered contour and internal complex structures such as a cavity, a pipeline and a cold pipe of the part through laser cutting. The third laser beam forms an Nth layer of slice through 3D printing, and the second laser beam performs synchronous laser shock forging in an optimal temperature region. The fourth laser beam works when the thickness of each layer of slice or each slice layer meets the requirements, thereby guaranteeing the dimension accuracy and the surface quality and realizing high-rigidity, high-accuracy and high-efficiency 3D printing. The device has the advantages of high machining efficiency, high quality and long service life.
