Técnica de la unión

La soldadura por termofusión entre tubería y accesorio constituye una unidad de material homogéneo. Dos elementos del mismo material son conectados directamente, sin necesidad de añadir ningún material de aporte. Las siguientes técnicas de soldadura son aplicadas en instalaciones de agua potable.

• Soldadura a enchufe
• Soldadura por electrofusión
• Soldadura a tope

Soldadura a enchufe

On heating element socket welding pipe and fittings are fused overlapping - and without application of welding fillers. The heating element is necessary for heating the outer pipe and inner fitting diameter. The heating element socket welding can be carried out either with a welding machine or with a weldingdevice. Two pipes are always connected with a fitting, like socket, elbow or tee. Fitting, pipe and heating tool must be coordinated insize by keeping the standard.

Soldadura por electrofusión

The electro-fusion fittings, applied for electro socket welding, are equipped with integrated resistance wires, which are current-carrying during the fusion process. By this the inner diameter of the socket and the outer diameter of the pipe are heated up to welding temperature resulting in a melting mass on both parts.

After their cooling there is an inseparable homogeneous connection.The necessary electrical energy is automatically supplied bysuitable electro-fusion devices. Environmental influences areconsidered by the barcode and temperature compensation of the electro-fusion device.

Soldadura a tope

While heating element butt-welding the connection surfaces of the parts to be welded are levelled under pressure at the heating element, then heated up to welding temperature with reduced pressure and after removal of the heating element joint under pressure.
