Powder for Welding Exothermic

The Exothermic Welding is a simple, effective, quality welding method, which weld the parts to desired size and type in graphite mold cave with overheat melting. Currently, exothermic welding replaced mechanical connections widely.Exothermic Welding Mold: The mold is made of a quality graphite body to obtain the perfect seal and lasting performance. The life of our mold can be 80-100 joints, which is more lasting than other competitors'.Exothermic welding powder: We mix the powder to comply with your conductor's material and size with a 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 of tools to meet your demand, including an ignition gun, brush, screwdriver, and glove. It is a packing box to meet your whole demand..(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 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:ElementRatio Wt/%Cu≥76.0Al≤2.0Fe≤10.0Physical properties of jointProperties of joint:PropertiesTechnology indexConductivityResistance of conductor (Including joint) should be less than that of same length base metalStrengthJoint strength should not less than 95% of low limit of raw material's strength (CCS material is regarded as pure copper )High melting point≥1083ºCSurfaceNo air hole,residue and crackSection qualityThe max size anywhither should be higher than 1/3 of the thickness(or 1/4 of diameter) ,but should be less than 3mmResistance of joint:Resistance/μΩTest location113Distance between tested location:15cmStrength of joint:Strength Rm/MpaRemark340No crack and base metal offStore instruction :The flame point of powder is very high , the store condition should be dry ,cool ,no shine ,no humidity.If the packing damaged ,please don't use.FAQ1.
