Abstract: PURPOSE:To improve mechanical properties with the fined metallic texture of a weld bead and to assure the build-up thickness of the weld bead easily by compressing the fluid weld bead formed successively according to propression of welding with a pressurizing roll thereby smoothing the bead. CONSTITUTION:A welding rod A and a pressurizing device 1 so as to be located behind the welding rod in the advance direction are first disposed in the welding position. While the rod A is melted by an arc or gas, the rod is moved leftward and the build-up welding of a butt part 3 is executed. The weld bead B formed successively during this time is compressed in the state of the molten bead C prior to solidifying with a pressurizing roll 5 which is operated so as to follow up the rod A. The metallic texture of the compressed bead C is fined in a compression stage and the surface of the bead is formed smooth. The bead is solified by a heat radiating effect. As a result, the metallic texture of the bead B is made fine and uniform, and the mechanical properties thereof are improved. Since the surface of the bead B is smoothed, the thickness of building- up is made constant, and the assurance of the constant thickness is made easy.

IPC: G09G3/22
Filed: 1994-03-22
Abstract: PURPOSE:To save electric power energy by controlling an electric field in an electron source in the way electrons are emitted only out of positions of a flat electron source facing to electron beam passing positions. CONSTITUTION:ON-voltage is applied to a divided back side electrode 16a from a divided back side electrode driving apparatus 17 and potential at which no electron is emitted out of a linear thermal cathode 1 is applied to other divided back side electrodes 16b-16i. Consequently, electrons 19 are emitted only out of a part of the electrode 16a through a small hole of a hole-having cover electrode 2. When ON-voltage is applied to only one of successively corresponding electrodes 16a-16i from the driving apparatus 17 while being timed to the scanning work to set a group of control electrodes at ON-potential, electrons 19 can be emitted only out of the electrode. As a result, electrons 19 are emitted only out of a part facing to the scanned position of the group of control electrodes of a flat electron source 4a, vain electron emission is suppressed and electric power is saved. Moreover, the electrodes 16a-16i are easily formed on an insulating film 21 after the insulating film 2 is formed on the face of a metal substrate 20.
