摘要： Provided is a seam welding device capable of seam welding various shapes of objects to be welded. A seam welding device which performs seam welding by causing electricity to be conducted between a first electrode wheel and a second electrode wheel comprises a first motor which drives the first electrode wheel, a second motor which drives the second electrode wheel, and a first belt provided between the first electrode wheel and the first motor. If a direction joining the axes of the first electrode wheel and the second electrode wheel is defined as a vertical direction, the direction from the first electrode wheel toward the second electrode wheel is upward, and the direction from the second electrode wheel toward the first electrode wheel is downward, then the first motor is disposed further upward than a point of contact of the first electrode wheel and the second electrode wheel.

摘要： A welding gun equipped with a retaining unit, which includes a first retaining member and a second retaining member, and retains a stationary gun arm and a movable gun arm. A retaining hole for retaining the stationary gun arm, guide grooves for insertion of rolling members provided on an arm holder that retains the movable gun arm, connecting member insertion holes into which connecting members connecting the first retaining member and the second retaining member are inserted, and a retained member insertion hole for inserting a retained member retained by a moving member that moves the retaining unit to a welding operation location, are formed in the first retaining member and the second retaining member, and the regions where these components are formed are set as thick-walled regions having a greater thickness than other regions. Thus, adequate rigidity is ensured while avoiding an increase in weight.
