[0002] The hot melting welding mode is a simple, efficient metal connection process, which uses the chemical reaction of metal compounds (welding powder) as heat source, and directly heats the welding body by the hot melting liquid generated by chemical reaction to form a certain shape and size in graphite mould. The hot melting welding process needs to use a special mould to fix the welding parts and hold the welding agent. The working principle is to put the copper stranded wire to be connected into the forming cavity of the mould, fix and clamp it, pour the welding agent into the combustion chamber of the mould, add the exothermic welding agent through the ignition port on the mould cover and ignite it.
