我段凡因花键部分磨损的传动轴均按此方法修复。一、堆焊:1.电焊条牌号为φ毫米、JD35;2.施焊电流为170～175安;3.堆焊部位为花键轴磨损侧面,花键根部末磨损处留出2～3毫米长度不进行堆焊,作器铣削键时的基准面;4.为减小焊接引起的轴弯曲,施焊时依次按顺序对边交叉焊接;

My section where the spline part of the shaft wear are repaired by this method. First, the surfacing: 1. Welding rod is φ mm, JD35; 2. The welding current is 170 ~ 175 A; 3. Welding site for the spline shaft wear side, spline root at the end of wear leaving 2 to 3 Millimeters of length without surfacing, when the machine milling key datum; 4. In order to reduce the shaft bending caused by the welding, when the welding sequence in order to cross the edge of the welding;
