Provided herein is a spar cap having a profile for guiding and receiving a shear web for wind turbine blade. Particularly, the present disclosure provides a pultruded spar cap having a bond gap feature to maintain a uniform space for distribution of bonding paste between the spar cap and shear web. Also, the spar cap is formed with locating features which guide and receive placement of the shear web.

Installation fittings for use with induction weldable pipe connectors for assembling multi-layer pipe fluid distribution systems. Induction welding pipe connectors including a major central pipe connector section and a minor lateral pipe connector section pair having reduced thickness relative to the major central pipe connector section. Induction welding pipe connectors with integral solder flow barrier for assembling fluid distribution systems. Electromagnetic induction coil reverse action pliers for use with induction weldable pipe connectors for assembling fluid distribution systems.

Induction Weldable Pipe Connectors (IWPCs) (400) for electromagnetic induction welding with at least one plastic pipe (30). IWPCs (400) include a tubular induction weldable mounting (401) having an opposite pair of induction weldable sockets (404A, 404B), a tubular cover (406) externally mounted on the induction weldable mounting (401), and a tubular pipe tang (407) internally disposed in one induction weldable socket (404A, 404B) for destining an induction weldable socket (404A, 404B) as an induction weldable pipe socket (408A, 408B) for forced sliding insertion of a pipe end (31) thereinto. The cover (406) includes an opposite pair of thermally insulated induction weldable socket mouth rims (426A, 426B) for entrapping melted solder lining (412) inside the induction weldable mounting (401) during an electromagnetic induction welding operation, thereby ensuring improved welding.

A method and device for connecting and repairing a shear web includes the method steps of dry-fitting a shear web insert in a rotor blade assembly to establish a perimeter gap at an angled perimeter interface between the shear web insert and the rotor blade assembly, the angled perimeter interface positioned between the shear web insert and at least one adjacent surface of a first shear web, a second shear web, a first side of the rotor blade assembly, and a second side of the rotor blade assembly, and then injecting a bonding paste into the perimeter gap. The rotor blade assembly can include a connecting device having at least one pre-fabricated clip.
