The invention relates to a plastic-welding device for connecting a first, thin-walled plastic part to a second plastic part in a planar manner. The device includes a hand-held mounting aid and a welding head that can be held in a retainer of a hand soldering iron; wherein the welding head has a main body and at least one welding tip arranged on the main body. The mounting aid has at least one spacer, which can be placed onto the thin-walled plastic part by means of an underside of the at least one spacer and on the surface of which the main body of the welding head can be supported. The spacer is designed so that, when the main body is supported on the at least one spacer, a depth of penetration of the welding tip into the plastic parts to be connected is limited to a predetermined maximum value.
A welding head for producing plastic rivet joints, the welding head in the form of a soldering iron attachment or soldering iron insert, wherein the welding head comprises a base body (21) with a bottom end face having an axially raised circumferential rim (17) and a welding tip (18) disposed at a center.
A welding head for welding two plastic parts together, the welding head in the form of a soldering iron attachment or soldering iron insert and comprising a base body (21) with a slanted bottom end face (23), the slanted bottom end face (23) comprising a welding tip (26) and an opening (25) of a bore (24), the bore (24) extending along a side of the base body to the slanted bottom end face (23) and adapted to introduce plastic for welding.
