    摘要: Method is disclosed for manufacturing a panel assembly comprised of an inner panel and an outer panel which are welded together at the peripheral portions thereof. The method comprises steps of forming a plurality of raised portions having projections in the inner panel along at least one peripheral portion thereof so that the raised portions project in a direction opposite to the outer panel, folding a peripheral portion of the outer panel over the peripheral portion of the inner panel so that the peripheral portion of the outer panel covers the raised portions in the inner panel, applying anvils to the outer panel at portions corresponding to the raised portions and applying welding electrodes to the peripheral portion of the outer panel which is folded over the raised portions of the inner panel so as to depress the peripheral portion of the outer panel to the raised portion simultaneously applying a welding current in series through at least two of the welding electrodes for welding the peripheral portion of the outer panel to the raised portion of the inner panel. The process is effective to prevent thermal deformations and depression marks on the outer panel.
