Patent ID: 8502103

Claim:
A submerged arc welding apparatus for performing submerged arc welding for a workpiece that is placed in a vertical position and has a welding line extending in a height direction, wherein the submerged arc welding apparatus comprises: (a) a flux receiver having an open side and adapted to receive and hold flux in an area defined by the flux receiver and the workpiece, wherein the area is disposed inside of the flux receiver when the flux receiver abuts against the workpiece on the open side; (b) a flux feeder disposed to supply flux to the flux receiver; (c) a welding torch disposed to supply a welding wire toward the workpiece with a tip of the welding torch disposed in the area; and (d) a moving mechanism operable to move the flux receiver and the welding torch along a direction of the welding line of the workpiece with the flux receiver abutting against the workpiece, wherein the flux receiver includes a body for holding the flux and a flexible flux sealing portion provided at an open side of the body, wherein the flux sealing portion includes a flexible skirt portion that flanges toward a lateral direction and a downward direction relative to a direction of the open side of the body, and an elastic member separate from the flexible skirt portion is disposed to elastically press the skirt portion to a surface of the workpiece.
