An apparatus for heat welding together thermoplastic components and work-pieces comprises a heating unit and a carriage unit. The heating unit is axially movable to contact and melt part of the work-piece to a sufficiently tacky state for the component to be fused thereto. The carriage unit releasably retains the component and is axially movable to move a component contact surface against the melted part of the work-piece, mounting the component thereto. The carriage unit is pivotally movable about the axis, whereby the initial contact of the component against a mis-aligned work-piece causes the component and the carriage unit to pivot so that the component contact surface is re-aligned with the melted part of the work-piece.
