Welding method for repairing seriously damaged steel rail of seamless track
The invention relates to a welding method for repairing a seriously damaged steel rail of a continuously welded track, and relates to the technical field of welding of steel rails of continuously welded tracks. The seamless track seriously damaged steel rail repair welding method comprises the following steps that the distance between a first mark and a second mark is obtained and recorded as a mark distance; cutting a part between the first mark and the heavily damaged steel rail and a part between the second mark and the heavily damaged steel rail; a replacement steel rail is inserted into the seamless track, one end of the replacement steel rail is welded to the seamless track, and the other end is a free end; the distance between the free end of the replaced steel rail and the first mark is obtained and recorded as a welding distance; and determining the distance between the stress locking welding head and the second mark when the free end of the steel rail is replaced for welding according to the mark distance and the welding distance. The marked steel rail lengths before and after welding are kept consistent, stress is prevented from being generated at the welding position, and it is ensured that the locking rail temperatures before and after welding are the same.
本发明涉及一种无缝线路重伤钢轨修复焊接方法，涉及无缝线路钢轨焊接技术领域。本发明的无缝线路重伤钢轨修复焊接方法，包括如下步骤：获取第一标记和第二标记之间的距离并记为标记距离；切割无缝线路位于第一标记与重伤钢轨之间的部位、第二标记与重伤钢轨之间的部位；向无缝线路中插入更换钢轨，更换钢轨的一端与无缝线路焊接、另一为自由端；获取更换钢轨的自由端与第一标记之间的距离并记为焊接距离；根据标记距离和焊接距离确定更换钢轨自由端焊接时的应力锁定焊接头距离第二标记的距离。使焊接前后的标记的钢轨长度保持一致，避免在焊接处产生应力，确保焊接前后的锁定轨温相同。
