通过大量试验研究了钛钙型耐候钢焊条药皮组分对焊条性能的影响规律。在此基础上研制出具有优良综合性能的耐候钢焊条 ,并在螺旋式焊条涂粉生产线上投入批量生产。该焊条可广泛用于 5 0 0 MPa级铁道车辆用低合金耐候钢及其它要求耐大气腐蚀结构钢的焊接。
Through a large number of experiments to study the titanium calcium weathering steel electrode coating composition of the electrode performance rules. On this basis, we have developed a weathering steel electrode with excellent overall performance, and put it into mass production on the spiral electrode powder coating production line. The electrode can be widely used for welding of low alloy weathering steels and other atmospheric corrosion resistant structural steels for rail vehicles with a diameter of 500 MPa.
