METHOD OF MAKING STRUCTURE AT METAL PART SURFACE Russian patent published in 2013 - IPC B23K9/04 F16B5/07 

FIELD: process engineering.

SUBSTANCE: proposed method can be used in production of connector 6 on metal party surface 4 in the form 3D structure 1 raised above the surface. Welding 7 is carried pout using at least one fused extra material 2. In welding cycle 8 of welding process 8 electric arc 3 is initiated between extra material 2 fed into welding torch 5 and part 4. Heat feed in welding process 7 is adjusted by setting of welding conditions. 3D structure 1 is composed stepwise of several separate elements 6. Every said separate element 6 is produced in one welding cycle 8 while after every welding cycle 8 break is performed in welding. Every welding cycle is started by arc initiation and terminated before the break 9. Electric arc 3 is quenched by adjustment of welding parameters. Separated element made in previous welding cycle is connected with separate element produced in the next welding cycle 8.

EFFECT: production of whatever connectors using whatever extra materials.
