RESEARCH ON PLATING PARTS USED IN THE OIL INDUSTRY

The paper includes a number of theoretical and experimental results on plating of several pieces from different classes focusing especially on the pieces of the flanges and housings class. For reasons of confidentiality to beneficiaries, the paper presents experimeindustry at the ends of probe drilling and extraction. Have been taken into account these kinds of pieces in the research due to operating conditions and high requests which occur during operation

CONTRIBUTIONS OF THE POSSIBILITY OF USING ULTRASOUND IN PLATING PROCESS PARTS

The efficiency of the plating process in the ultrasonic field is primarily dependent on the mode of \ud introducing the ultrasonic energy into the welding bath. The research undertaken has revealed that the \ud propagation\ud of ultrasound in the liquid metal bath has a significant influence on the transfer process filler \ud material through the electric arc and on the process of crystallization. All these influences are attributed to the \ud two basic phenomena due to the propagatio\ud n of ultrasound in liquid enviroments and ultrasonic cavitation and \ud the acceleration of diffusion process

CONTRIBUTIONS REGARDING IMPACT ON THE NATURAL ENVIRONMENT OF A NUCLEAR EQUIPMENT BULIDING COMPANY

Paper presents how to determine the environmental impact of nuclear equipment manufacturingcompany. Here are analized the most important sources of environmental pollution (booth blast, furnace annealing and thermal plant) and principal emissions and pollutants of the environment are determined in five distinct points within 200 m of the enterprise, using a measuring original stand. According practical determination, CO,SO2 and NO2, concentrations exceed normal values presented in the 462/93 Government Order
