Abstract：Miebach CSLH21 laser welder is inducted in Shougang Jingtang 2 230 mm cold strip mill and used for the weld of the low carbon and HSS coils. The strips which can be welded were a variety of steel, including low carbon steel, high carbon steel and duplex steel in a width range of 800- 2 150 mm and in a thickness of 0.4- 2.5 mm. The influence of laser welder′s bad shear cutting precision on the quality of the weld seam in the CAL line was introduced. Through the adjustment of the shear unit, it recovered the shear cutting accuracy, and greatly improved the welding quality, reduced the rewelding rate and parking rate of laser welder in the cold rolling annealing process.
