China UL-Listed Exothermic Welding Powder

Can be used different metal's connectionConnection between conductors and earth rodGenerated with several chemical substances after aluminum heating reaction under high temperature and weldingCurrent carrying capability from welding point is same as conductor with good conducting performanceAfter inspection, the DC resistance ratio and change rate are almost zero before and after weldingLevel that any of the traditional welding method cannot be comparedNo need of resources from outsideCan be operated indoor and outdoorWon't damaged by surge currentTest shows the conductor will be melted earlier than welding point's when under high current impact in short periodCorrosion or slack will not produced from weldingWeld junction, no contact surface, no residual stress, junction is stable and reliable as long term conductive bodyWelding junction, connector and conductor are combined on molecular so it has a good mechanical strength and is a permanent junctionEquipment is simple, convenient and handyEasy operation and can done without professionals
