A solder pot is provided in the form of an elongated pot for containing molten solder, at least one elongate coupling member extending longitudinally of said vessel and fixed on the outside thereof in energy transfer relationship therewith, a multiplicity of vibratory transducers equally spaced along said coupling member and affixed thereto, a power generator and oscillator connected commonly to all said transducers and means for uniformly heating the vessel and metal therein.

Apparatus and methods for fluxless soldering

A method and apparatus for skimming liquids such as solder are provided for removing the surface layer to produce a clean fresh surface by breaking the surface at two parallel spaced confining boundaries and moving the confined surface unidirectionally.

Methods and apparatus for skimming liquids

A method and apparatus for fluxless soldering, particularly of capillary joints, is provided wherein the part to be soldered is immersed in a bath of molten solder, the solder is caused to cavitate and simultaneously the part is subject to vibratory or impact energy.

Methods and apparatus for soldering

A method and apparatus for fluxless soldering, particularly of capillary joints, is provided wherein the part to be soldered is immersed in a bath of molten solder, the solder is caused to cavitate and simultaneously the part itself is set into a sympathetic mode of vibration by means of low frequency amplitude modulated variations or harmonics and sub-harmonic variations imposed on the bath.

A method is provided for eliminating 'icicles' or ligaments and other manifestations of dripping solder from articles which are dip soldered by vibrating the articles simultaneously with removing them from the solder bath and continuing to vibrate the articles until the solder thereon has at least levelled.

Methods of dip soldering

An ultrasonic flame soldering tool is provided which combines an ultrasonic contact probe and an acetylene air torch into a compact, convenient soldering unit. The tool can be used for soldering new or previously soldered joints in aluminum or other metals without the necessity of using a flux.
