发明名称 WATER-COOLED SLIDING COPPER STRAP FOR ELECTROGAS ARC WELDING
摘要 <P>PROBLEM TO BE SOLVED: To discharge molten slag, generated on a molten pool in welding, from the molten pool efficiently. <P>SOLUTION: In a sliding copper strap for electrogas arc welding which slides in a moving direction of welding while contacting the surface of a to-be-welded material of a groove part of electrogas arc welding, a first trench 16 and a second trench 17 are provided in order from upper side to lower side on the surface facing the groove part of the to-be-welded material of the water-cooled sliding copper strap. The first trench 16 is parallel to the surface of the to-be-welded material and provided for forming a weld bead, and the second trench 17 continues to the lower part of the first trench and is inclined against the surface of the to-be-welded material to discharge the molten slag, and further, in the second trench 17, the trench width gets wider in order from the upper side to the lower side (&theta;1), and the trench depth gets deeper in order from the upper side to the lower side (&theta;2). <P>COPYRIGHT: (C)2012,JPO&INPIT
