ESTWELD® RAILWAY SIGNALING BOND
Exothermic welding is one of the most popular methods of railway signaling bond.
ESTWELD® Weld Metal E20A
ESTWELD® weld power is a mixture of copper oxide and aluminium , packaged by size in individual plastic tubs or bags.
ESTWELD® SAFE WELDED HIGH-VOLTAGE POWER CONNECTIONS
ESTWELD® SAFE high-voltage welds are permanent molecular bonds that cannot loosen or deteriorate, no maintenance is required and no resistance increase over time, so there is a continuous optimal electrical path.
ESTWELD® SAFE
Continuing the tradition of technical leadership, ESTWELD® SAFE was developed as a simplified method of performing exothermically welded electrical connections.
ESTWELD® Molds
The shape of the mould, its dimensions, and the size of the welding material, are all dependent on the items to be welded.
ESTWELD® Weld Metal E20A
weld power is a mixture of copper oxide and aluminium，These containers are packaged in plastic boxes with the corresponding metal disks.

Exothermic Welding Connection Process
The Exothermic Welding Connection process is a simple efficient method of Welding copper to copper or copper to steel. One advantage is that NO outside power is required when using the Exothermic Welding Powder. The Exothermic Welding Process uses high temperature reaction of powdered copper oxide and aluminum.
Exothermic Welding consists of copper oxide and aluminum oxide, the most important one being that the process produces a molecular joint and not just a mechanical one in between the conductors. It is produced through a starting reactant which enough energy to activate the Welding reaction. This takes place quickly and safely inside a graphite mould. The mould is designed specifically for a certain union depending on the elements to be welded and the joint type required. We guarantees all types of joints not only copper cable unions but also to Welding tapes, brass metallic pieces, stainless steel, steel ground rods covered with copper, etc. It is especially useful for joining dissimilar metals.
