A method for integrating a fitting (110) fitted between two wings of a composite profile (100) comprising the steps of: i) obtaining a preform of a fitting impregnated with a thermosetting resin, comprising two flanges (111) and a rib (114); ii) pre-curing the laminate preform of the fitting to obtain a partial polymerization of the preform; iii) laying up a laminate preform of the profile so that fibers impregnated with a thermosetting resin included in two of the wings of the laminate preform of the profile are laid up over the two flanges of the preform of the partially polymerized fitting; and iv) completely polymerizing an assembly comprising the laminate preform of the profile and the laminate preform of the partially polymerized fitting while maintaining into contact the flanges of the laminate preform of the fitting with the wings of the laminate preform of the profile.

The invention also pertains to a tooling for implementing the method and a wing spar obtained by this method.

A device, a method and a movable welding apparatus for thermal joining of respective two material sheets over a connecting piece arranged areally on a bottom side, wherein the material sheets are arranged with a respective side surface facing one another abutting against each other at least partially with a respective bottom side lying areally on a top side of the connecting piece are provided. In particular, the two material sheets and the connecting piece can be joined together in one pass.

An apparatus for welding polymeric pipes such as pipe segments in a pipeline welds first and second pipes around a circumferential weld zone and has one or more welding heads, a carriage for guiding the one or more welding heads around the circumferential weld zone and a drive arrangement for effecting relative rotation between the pipes and the or each welding head. The or each of the welding heads has a body and a heating element carried by the body for supplying heat to the circumferential weld zone to cause melting thereof. The heating element is arranged to reciprocate relative to the body of the welding head between a retracted and an extended configuration such that as the heating element moves from the retracted to the extended configuration the heating element melts and penetrates the surface of the circumferential weld zone forming a weld.

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.
