Abstract: An arrangement for soldering aluminum objects which are coated with solder, especially coolers and heat exchangers, comprises at least one oven section and a cooling chamber. A transporting arrangement, especially a carriage, advances the objects to be soldered in succession through the oven section and the cooling chamber. A heating arrangement and a controllable blower are arranged in each of the oven sections provided, being operative for directing heated air against the objects advancing through the respective oven section. A first temperature sensor measures the temperature upstream of the objects as considered in the flow direction of the heated air, while at least one second temperature sensor is arranged at the opposite side of the object from the first sensor and is operative for measuring the temperature of the air that has been discharged from the object after it has intimately contacted and heated the same. An auxiliary radiation heating arrangement may be provided, so that the objects are heated both by convection heat carried by the air flow that has been heated by the heating arrangement, and by radiation heat emanating from the radiation heating arrangement to thereby achieve a uniform temperature increase and thorough heating of the object from both sides.
