[0002] In the field of furnace tube manufacturing and repair, welding is one of the key processes for connecting furnace tubes. However, in the traditional furnace tube welding process, due to the differences in furnace tube size and shape, as well as various errors that may occur during welding, the accuracy of the connection has become a difficult problem to solve.

[0003] First, the size and shape of furnace tubes may vary depending on production batches, operating environments, and maintenance needs. Traditional welding auxiliary devices often lack sufficient flexibility and adaptability, making it difficult to meet the welding requirements of furnace tubes of different sizes and shapes. This results in the difficulty of precisely controlling the butt joint position of the furnace tubes during the welding process, thus affecting the welding quality.

[0004] Secondly, errors that may occur during the welding process are also a significant factor affecting the precision of the weld. For example, the skill level of the welder, the precision and stability of the welding equipment, and the properties of the welding materials can all influence the weld quality. Traditional welding auxiliary devices often lack effective control and compensation for these errors, making it difficult to guarantee weld quality. Utility Model Content

It can be raised, lowered, and moved laterally to adjust the docking position, improve docking accuracy, effectively reduce manual operation, improve work efficiency, and ensure stability and safety during the welding process. After electric welding and fixing, the furnace tube can be rotated through the roller 291 to facilitate welding.

[0024] Furthermore, the base frame 21 is longitudinally slidably connected to the frame 1. A platform is provided on the upper side of the frame 1, and a dovetail groove 11 is provided on the platform.
