Description

Technical Field

[0001] The utility model relates to the field of lightning rod production, in particular to an exothermic welding device with high processing safety. Background Art

[0002] Nickel alloy is an alloy composed of nickel as the base and other elements. Nickel has good mechanical, physical and chemical properties. Adding suitable elements can improve its oxidation resistance, corrosion resistance, high temperature strength and improve certain physical properties. Since lightning rods are often exposed to the atmospheric environment, the material is required to have good corrosion resistance; and nickel-chromium alloy wire, with its stable chemical properties and corrosion resistance, can effectively resist chemical corrosion and oxidation in the atmosphere. As a metal material, nickel-chromium alloy wire has good electrical conductivity. During use, lightning rods need to be clad in nickel alloy by exothermic welding (also known as aluminothermic welding), which is a method of using the superheated molten metal generated by the exothermic reaction between metal oxides and metal aluminum to heat the metal and achieve bonding. The existing lightning rods use a torch to ignite the ignition powder for exothermic welding. After ignition, the sparks at the ignition port are easy to splash and injure people, which poses a safety hazard and brings certain adverse effects to people's use process. For this reason, we propose an exothermic welding device with high processing safety. Utility Model Content
