Restoration of the cooling systems radiators using flame brazing through oxyhydrogen flame

摘要

Efficient restoration technology of the cooling systems radiators parts produced of aluminum and copper alloys with low-temperature fluxless flame brazing through oxyhydrogen flame uzing brazing Sn-Zn system alloys alloyed with gallium is developed. Application of the portable gas-welding apparatus MEB-50 allows to reduce restoration net cost using low-cost oxyhydrogen gas mixture instead of expensive balloon gases with high quality of obtained joints.
