Ship wedding process of ship building butt for accuracy and welding works in ship

摘要

PURPOSE: A cast plate linear welding method of a hull setting/welding work is provided to readily load by protruding a cast plate, to save welding materials, welding capacity and time and to save costs by minimizing contraction caused by heat deformation. CONSTITUTION: A regular gap is kept to weld a three-dimensionally assembled block with front and rear blocks. Upper and lower faces where a beam is formed are regulated by a wedge piece and a tooth tool to equalize a level for butt-welding. A restriction work is performed with the wedge piece and wedge to keep a cast plate level. A back bead is formed on a rear face of the cast plate by welding passes(1,2). An upper wedge piece and the wedge are removed and a removed part is finished. In a state that the tooth tool is attached, an inner member is perfectly welded and a finishing work for a welding portion is completed as needed. After removing the tooth tool in a state of fixing the cast plate and inner member, all the welding works of the inner member and cast plate are finished. Then, a work for cast plate linear welding is completed by a finish work as needed.
