TRENDS AND PERSPECTIVES OF HOT METHODS FOR RECONDITIONING OF WEAR DETAILS

The structure, trends and perspectives in development of hot methods as such used for reconditioning of worn details during the new Millennium are presented in the article as well as trends in production of consumables in industrially developing countries. The structure of welding methods is also shown giving priority to its development until 2020. It can be concluded that in the industrially developed countries by 2020 the share of arc welding will be stabilized at levels of 10-15% of the total number of methods used for weld overlaying of worn-out components. These figures will be 45-55 % and 7-9% for gas shielded and submerged arc welding respectively. The welding methods that will be prioritized for the period until 2020 will be gas shielded arc welding, contact, laser beam and hybrid welding.
