| Abstract: | The cladding preparation technology for the micro contact profile is investigated through the way of seam welding. The effects of the seam welding on different conditions including welding electrical current, welding time, electrode force and electrode material were contrasted through the way of metallographic structure, electron scanning, experiments of rectification and twist fatigue. The parameters of welding several kinds of materials were obtained. As a result, the qualified contact profile can be produced by making a control of the technical conditions: welding current, welding time, electrode force and electrode material. |
