BahraWeld
BahraWeld is an exothermic welding system that does not require an external source for heating. Exothermic welding is preferred where highly conductive, strong connections are required, these connections are permanent and do not loosen over time and withstand repeated fault conditions.
Major three parts that comprise this welding system are:
Molds:
Molds are made from optimum density graphite that lasts for 50 to 80 welds. The density of graphite and design of mold is selected based on various factors,
- Life of molds to withstand repetitive opening, closing, firing and cleaning cycles for 50-80 connections. (Higher the density of graphite, higher is the life)
- Time of welding/dissipation. (The lower the density of graphite, faster is the heat dissipation).
- Type of connection, size and complexity of connections, etc.
In addition to the standard molds listed in this catalog, Bahra Weld offers a wide range of customized molds for power stations, railways and other unique applications.
Weld Metal:
Weld metals are available in the form of powders and tablets. Weld metals are made from copper and aluminum oxides. The content of metal varies based on the size and type of the joint required. Ignition / starting powder is an explosive which initiates the combustion process of weld metal.
Tools:
- PPEs such as gloves and goggles are mandatory for the BahraWeld process.
- Handle clamps are required for opening and closing and to hold the graphite molds during the welding process.
- Fint guns or electronic ignition tolls are required for initiating the welding process.
- Scraper, Brush and other cleaning tolls are needed to clean the molds, conductors and joints.
