[0030] The online rolling system for longitudinal welds of annular steel strips in this embodiment has significant technical advantages, mainly reflected in the following aspects:

[0032] 2. Improve welding quality: Effectively eliminate weld gaps and remove gases and impurities from the welding process, thereby improving welding quality and preventing problems such as corrosion and oxidation.

[0033] 3. Reduced operational difficulty: Online continuous compaction can reduce the labor intensity and operational difficulty for workers, and improve work efficiency.

[0034] 4. Improve steel strip quality: Significantly improve the quality of steel strip. After rolling, the weld seam of the steel strip is smooth inside and out, with uniform thickness, which can enhance the density of the weld seam and achieve the effect of reducing internal stress.

[0035] 5. Reduced cracking: The compacted weld material has increased density, improved performance, and enhanced ductility, thereby reducing cracking during weld operation.
