ABSTRACT:
Submerged-arc spot welding apparatus has a carriage for supporting a welding means which is displaceable along a track disposed above a bed or table supporting the work. The carriage is provided with a pressure mechanism consisting of a pressure cylinder guided for motion in the carriage towards and away from the work, a piston in the cylinder having a piston rod attached to a thrust member which is moved into engagement with the work by the outward stroke of the piston. The corresponding backward thrust acting on the cylinder is taken up by stop means rigidly connected to and extending along the track. A stop on the carriage serves to take up the weight of the cylinder when the drive pressure is shut off.
