20130074994 | Method for Manufacturing a Plate Heat Exchanger - Manufacturing a plate heat exchanger calls for punching plates, each of which having at least one projection in the form of a hollow truncated cone, cleaning surfaces of the plates, composing a plate assembly by mounting the projection of one plate into opening of an adjacent plate. A predetermined gap between adjacent surfaces of the plates is maintained, a channel for passing a heat carrier is formed. A soldering paste solution based on copper hydrocarbonate and nickel salts is prepared, into which the plate assembly is immersed, the applied solution is dried. The plate assembly is placed into a high-temperature through-type conveyor furnace with a protective medium containing free hydrogen. Two temperature zones are provided along the way of movement of the plate assembly. The plate assembly is annealed in the first temperature zone and then soldered and covered with the copper-based alloy in the second temperature zone. | 03-28-2013 |

20140366996 | METHOD OF CLADDING AND FUSION WELDING OF SUPERALLOYS - The present concept is a method of cladding and fusion welding of superalloys and includes the steps of firstly application of a composite filler powder that consists of 5-50% by weight brazing powder which includes melting point depressants, and 50-95% by weight high temperature welding powder, to a superalloy base material. Secondly there is simultaneous heating of the base material and the composite filler powder by a welding heat source that is movable relative to the base material. There is heating to a temperature that will fully melt the brazing powder and at least partially melt the high temperature welding powder and also melt a surface layer of the base material, thereby forming a weld pool. Thirdly upon solidification and cooling of the weld pool, there is coalescence between the weld bead and the base material. | 12-18-2014 |
