The invention belongs to the technical field of heat release melting soldering powder, and particularly relates to copper-clad steel grounding grid heat release melting soldering powder suitable for cyclic wet-dry environments. The heat release melting soldering powder comprises the following components of, by weight, 30-50 parts of copper oxide, 2-10 parts of cuprous oxide, 8-15 parts of aluminumpowder, 18-28 parts of copper powder, 3-12 parts of copper-phosphorus alloy, 2-6 parts of nickel-chrome-cobalt-molybdenum alloy, 2-5 parts of fluorite powder, 1-4 parts of rare earth, 1-2 parts of borax and balance alloy additive powder. Through the soldering powder prepared through the invention, the problems that copper-clad steel welded through existing heat release melting soldering powder isprone to having the defects of pores, slag inclusion, hot cracks and the like and is poor in ocean atmosphere corrosion resistance are solved.
