DEVICE FOR FRICTION WELDING WITH MIXING, METHOD OF WELDING BY SAID DEVICE AND ARTICLE THUS PRODUCED Russian patent published in 2011 - IPC B23K20/12 

FIELD: process engineering.

SUBSTANCE: invention may be used in friction welding of parts made from metal or alloy with high melt point of 1350°C or higher. At least, a section of the device brought in contact with processed parts has chemical composition including iridium and one of the following elements, i.e. rhenium, ruthenium, molybdenum, niobium, tantalum, rhodium or two or more of there elements and one of the following elements,i.e. zirconium, hafnium, lanthanum, cerium, samarium, gadolinium, scandium, yttrium, or two or more said chemical elements, with 300 HV.

EFFECT: reduced abrasive wear, ruling out easy destruction due to reduced amount of impurities in welding zone.
