Description
The Exothermic Welding is a simple, effective,quality welding method,which weld the parts to desired size and type in graphite mould cave with overheat melting.Currently,the exothermic welding replaced mechanical connection widely.
Exothermic Welding Mold: The mould is made of quality graphite body to obtain the perfect seal and lasting performance.The life of our mould can be 80-100 joints,which is more lasting than other competitor’s.
Exothermic welding powder: We mix the powder comply with your conductor’s material and size with reasonable ratio ,so the joint is more strong and more lasting.
Exothermic Welding Clamp: The clamp make sure the mold is closed during welding. We can provide the scale of the mold, or we can make the clamps according to the customer's demand.
Welding toolbox: We offer the full sets tools to meet your demand,including ignition gun,brush,screwdriver and glove. It is a package box to meet your whole demand.
Product Parameter
The Size OF Exothermic Welding Powder
Product Advantages
(1).Good current loading ability:The welding point current loading ability is same to that of conductor;
(2). Good mechanical performance: The connection is a molecular connection. It is a permanent connection ,no loss or corrosion result to high resistance;
(3). Stable dash current resistance: The test shows that in the surge of big current in short time, and the conductor melts earlier than the connection point, no damaged by surge current.
(4). Good resistance to corrosion: The welding joint is covered by copper and more strong than copper, it provides good resistance to corrosion.
(5). Simple and safe connection: Neither outside power nor facility is required. It take very little time to finish one welding both indoor and outdoor.
(6). Free control the reaction temperature: Different welding powder is provided according to the metal features, so the welding powder can be very solid.
Welding Property
Welding Fluxe is also called aluminium heat welding powder.Use proper exothermic fluxes to make the connection joints more solid and extend the using life.
Main content and ratio of welding powder:
Properties of joint:
Resistance of joint:
Strength of joint:
Store instruction :The flame point of powder is very high ,so pyrophoric powder is must to ignite, the store condition should be dry ,cool ,no shine ,no humidity.If the packing damaged ,please don’t use.
