A system for connecting electronic assemblies, in particular a soldering and/or sintering system, has a transport device for conveying the assemblies through the system, with a plurality of gas-tightly separable modules for connecting the assemblies to one another. At least one module is a soldering and/or sintering module and one module is a cooling module. Between the soldering/sintering and the cooling module, a further module is a soft cooling module for cooling between a process temperature of the soldering or sintering module and an intermediate temperature, in particular below a solder solidification temperature. In a soldering or sintering module in a gas-tightly sealable process chamber, in particular in the soft cooling module, at least one heat source is contactable with the assemblies for heating the assemblies and at least one cold trap is arranged, having in operation a surface temperature which is lower than a heat source operating temperature.

A container for distilled spirits includes a stainless steel body, stainless steel top element and stainless steel bottom element wherein the body, top element and body element are joined together without solder such that the flavor of the distilled spirits therein is preserved. A method of making the container is also disclosed.

An arc welding apparatus and corresponding method includes a torch, a non-consumable electrode and a consumable electrode both disposed within the torch, a wire feeder configured to feed the consumable electrode in a vicinity of the non-consumable electrode, a first power source and a second power source that provide independent current, respectively, to the non-consumable electrode and the consumable electrode, and a weld process controller to control outputs of the first power source and the second power source such that a concentrated arc is formed, as a heat source, between the non-consumable electrode and a workpiece, and an inter-electrode arc is formed between the consumable electrode and the non-consumable electrode to melt the consumable electrode. The approach is characterized by low heat input, low distortion, low spatter, and the relative high speed or high deposition of laser and laser-MIG hybrid and other forms of multi-wire/multi-electrode welding, cladding, and additive manufacturing.

A processing method of formic acid soldering includes providing a solder, performing a formic acid providing step, performing a soldering step and performing a cooling step. The solder is disposed at a soldering object. In the formic acid providing step, a water-containing formic acid vapor extracted from a formic acid source is introduced to a soldering object so as to form a water-containing formic acid atmosphere surrounding the soldering object. In the soldering step, the solder and the soldering object are soldered in the water-containing formic acid atmosphere at a soldering temperature so as to form a soldered object with high temperature. In the cooling step, the soldered object with high temperature is cooled by a cooling method so as to form a soldered object. A range of a moisture content of the formic acid source is greater than or equal to 0.1 wt % and less than 15 wt %.
