There are shown the wide possibilities of combined micro plasma welding methods.They permit,for example,to do the local surfacing without essential deformations of rather thin jewelry elements,including a big growth a rise or layer of metal which exceeds it thickness in 2~8 times at the space with the approximately the same sizes.Such opportunities are based on the various possibilities of the joint producing - with different participation of metal parts and filler material.It may be added as a standard paste,wire,strip,etc.An operator can easy choose - where it is reasonable to apply only welding or brazing process as well as their combinationsdue to his qualification,the concrete jewelry good design,needed accuracy of the given joint adjustment and,of course,the operators fantasy.At the same time he has excellentchances to repair the spoiled jewelry good or its element.All these processes are very easy for realization and theymay be even made by beginners and not only in jewelry,but also forrepairing of copper tubes,brass heat exchangers,various bronze goods,in dental purposes.
