Description:
The exothermic reaction occurs between copper oxide and aluminium powder (contained within the weld metal) creating molten super-heatedcopper and an aluminium oxide slag. When an ignition spark comes into contact with the weld metal, it causes an exothermic reaction withinthe weld metal, melting and separating the metals.
The aluminium rises to the top of the connection creating a slag leaving the molten coppeito flow around the joint, creating the weld.
The exothermic connecion is a permanent, maintenance-free weld that wil not loosen overtime or deteriorate with age.
The connections' curent carying capabilty is equal to or greater than that of the conductors being joined. In other words. there is no increase inresistance in an exothermically welded connection, unlike in most pressure type (bolt/crimp) connections.
Throughout the word, exothemic welding has been shown to be the best choice where safety, reliabilty, curent carryjing capacity andlongevity are critical.
The exothermic process is a simple, self-contained, effcient way of welding copper-to-copper or copper-to-steel
Each connection uses a weld metal which, when ignited, creates an exothermic reaction between copper oxide and aluminium powder.
The connections are produced inside a graphite mould, specifically designed to suit the size of conductors to be welded as well as the specificjoint configuration.
Each connection requires a specific mould designed to suit the joint configuration and conductors being used.
Each mould type requires a specific weld metal size.
Once the correct mould and weld metal have been selected, the process is simple and straightforward.
Operation Instruction
l Check to ensure the graphite mold and conductor is clean ,no residue before making the connection
l Use a propane torch to dry wire conductors and remove remaining cleaning residue, solvent, or water before making the connection.
l Close the graphite mold lid before ignition ,and close the lid tightly
l Insert the conductors and position them for the connection.Ensure them in the center of cavity.
l Keep the irrelevant personnel 1.5M away when welding
l Keep the inflammable goods 1-2M away when welding
l The operator must be equipped thermal barrier glove
l Don't face to the mould opening when welding
l The operator keep 1.5M away mould is must after ignition
l Don't touch the mould and connected parts directly after welding
l Open the mould and take the joint out with wrench 10-20S later after reaction .
l Insulate the joint after the conductor cooling completely .
