施焊时采用分段跳焊法：根据焊缝长度先对焊缝进行分段，每段长400mm左

When welding, use segment jump welding method: first segment the weld according to the length of the weld, and each section is about 400mm long. When the length of the end section is less than 150mm, it is combined with the adjacent section as one section, and when it exceeds 150mm, it is regarded as a separate section. During welding, the two welders apply welding symmetrically to both sides from the middle according to the welding sequence in the above figure, and perform inter-section welding. After each section of welding, strike the weld evenly with a hand hammer for about 5 minutes to fully release the stress. The four corners are finally welded at a distance of about 200mm to relieve the stress generated during the welding process. When the deformation is found to be obvious during the welding process, the welding should be stopped immediately and the weld should be knocked.

Welding is performed using segmented jump welding method: according to the length of the weld first to the weld segment, each segment length of about 400mm, the end section length of less than 150mm with the adjacent segment merged as a segment, more than 150mm as a separate segment. During welding, two welders perform symmetrical welds on both sides from the middle in the order of welding in the figure above, and perform staggered welding in segments. After each weld, hit the weld with a hammer evenly for about 5 minutes, so that the stress is fully released. The four corners are welded at a distance of about 200mm to release the stress generated during the welding process. When the deformation is found to be more obvious in the welding process, the weld should be stopped immediately and the weld should be hit.

During welding, the method of sectional skip welding is adopted: according to the length of the weld, the welding seam is segmented first, and each section is about 400mm long. When the length of the end section is less than 150mm, it is combined with the adjacent section as a section, and when it is more than 150mm, it is taken as a separate section. During welding, the two welders shall start from the middle and weld symmetrically to both sides according to the welding sequence in the figure above, and carry out staggered welding of intervals. After each welding section, knock the weld evenly with a hammer for about 5 minutes to fully release the stress. The four corners are about 200 mm away from the final welding to release the stress generated during welding. If obvious deformation is found during welding, stop welding immediately and knock the weld.<br>
