Description

A laser welding machine welding seam dust automatic purging device

technical field

The utility model relates to the field of cold rolling, in particular to an automatic purging device for welding seam dust of a laser welding machine.

Background technique

During the production process of the pickling head of the cold rolling mill, the iron sheet ash on the hot-rolled strip falls on the bridge platform. When the unit produces strip steel from narrow to wide, especially when the unit produces extreme wide material, when the lead enters the welding machine, the ash on the bridge platform will be brought to the welding machine splint platform and on the strip. surface. When welding with a laser welding machine, due to the presence of iron scale ash on the upper surface of the strip with the head and the tail, the weld will produce pores. Production operators had to re-weld, and before re-welding, manually clean the top surface of the strip of scale dust. Not only does it increase various gas losses, but also because of re-welding, the rolling mill has to reduce the production speed or stop due to the re-welding of the welding machine. Moreover, if the production operator finds out that it is not timely, the strip will be broken in the rolling mill, and in serious cases, the welding seam will be broken at the tension leveler.

SUMMARY OF THE INVENTION
