N’Akron connector is made of a material suitable to bewelded by arc melting.
The dimensions and design of the connector are in accordance with the UNE - EN ISO13918:2008.
N’Akron connector is available in diferent materials, the properties of each can be documented by a test report 2.2 or by a certificate of inspection 3.1 or 3.2 (EN - 10204)

Unalloyed structural steel.

The unalloyed connector to welded by arc melting is made of steel materials belonging to Group 1 in accordance to the standard ISO/TR 15608:2005 requiring very stringent carbon content, the degree of purity, grain size and characteristics of its surface, this makes the material particulary suitable for N’Akron welding connector.

We supply connectors manufactured with steel Group 1, and with the following mechanical properties.

Tensile strength Rm $ 450 N/mm2
Yield strength Rel $ 350 N/mm2
Elongation A5 $ 15%

These connectors exceed the requeriments of UN - EN ISO 13918:2008

89/106/EEC

Certificate N0. TC.11/005804 dated 31/05/2011 by UKTC. UK Product Safety Test Center Limited

CONNECTOR DIMENSIONS

The nominal length is the length of the connector after the welding. Connectors provided for welding, are between 1 to 5 mm longer.

N’Akron connectors by arc welding with ceramic ferrule protection, are supplied with a small ball of aluminium at its end as required by the welding process, to facilitate the opening of the arc, stabilize it and deoxidize the surface of metal base.

The correct amount of &ux used is a key factor to obtain a perfect result in the weld.

Ceramic ferrule

In the welding of connectors, ceramic ferrule forms a combustion chamber surrounding welding, protecting welder from both arc and welding projection.

Concentrates arc in a reduced area and limits the loss of heat and cooling rate.

The ceramic ferrule is used for a single weld and removed once the molten metal has solidified.

Welding collar

In the process of the pin welding, collar is formed at the welding joins of the workpiece.
Its dimensions depend on welding parameters and the ceramic used.
