KLK

KLK WELD exothermic Welding Process  uses the high  temperatures generated by the reaction between copper oxide and aluminum to melt and subsequently fuse objects with the welding material. The reaction takes place within a mold or crucible, into which the welding powder and pieces to be welded are introduced in their respective positions.

After  the  welding mixture is ignited, the molten metal flows into the chambers within the mold forming homogeneous bond with the pieces to be joined.

The reaction is so quick that the pieces to be welded get a lower temperature, on the zone around the welding point, than that arising when using other process. This is an important fact for protecting insulated cables or physical characteristics of the pieces to be welded. The KLK WELD process may also be used in addition to welding copper to copper, steel-copper, etc.

The KLK WELD connection is a perfect molecular weld:

• Connections are not affected by high current surges. Tests have shown that the electrical conductors will melt before the connection when subjected to high short-circuit current.
• Connection conductivity is at least equal or greater than the conductors welded.
• There is not possibility of corrosion at the point of the weld, since conductors become an integral part of the connection.
