<p>Disclosed is an apparatus to continuously weld a steel sheet. According to an embodiment of the present invention, the apparatus to continuously weld the steel sheet is provided to remove a weld bead protruding from a welding area to prevent rolling loads, strip breakage and defective products from being generated due to the welding bead in a following process, and deformation twining from occurring due to the pressed welding area. The apparatus to continuously weld the steel sheet comprises a welding machine welding a connection part of preceding and following steel sheets which are consecutively and continuously supplied, while moving in the widthwise direction of the steel sheet against the direction of progress of the connection part; a post-heating device installed on the rear end of the direction of progress of the welding machine which treats the connection part by post-heating while continuously moving; and a cutting unit installed on the rear end of the post-heating device to cut the welding bead formed on the welding area during the process of welding.</p> |
