1. Contrastive Research on Electrical Contact Performance for Contact Materials of Cu-SnO2 and Cu-ZnO2 Alloys
Herein, SnO2- and ZnO2-doped (1.5 wt.%) composite Cu powder was prepared by mechanical alloying (MA) respectively, and both the contact materials of oxide-doped Cu alloys were subsequently obtained by canned hot-pressing powder sintering with hot extrusion combined. Scanning electron microscopy (SEM), laser scanning confocal microscopy (LSCM) and self-design

2. Development of a Powder-feed Device and Procedures for the Application of an Experimental Alloy in Overhead PTA-P Welding
Abstract: When they are damaged by cavitation, hydroelectric power plant turbine blades must be repaired using operations that could benefit from developments in welding technologies. In light of this, the LABSOLDA welding laboratory at the Federal University of Santa Catarina is making efforts to enhance the flexibility and robustness of the powder-fed plas

3. Valoraciones empírico-teóricas sobre los métodos de evaluación de la transferencia de carga eléctrica en la soldadura con electrodo revestido
The present work is based on an assessment of experimentally obtained results from the application of different methods of evaluation, reported in the specialized literature, of the electrical charge transference stability in the arc. A simple factorial design, taking the welding current as independent variable, was applied to the process with an AWS A5.1 E6

5. Valoración del desempeño de un dispositivo de autoalimentación diseñado para la evaluación operativa de electrodos revestidos
The objective of the present work is to evaluate the effectiveness of a self-feed device for covered electrodes. This device is able of eliminate disturbances from manual operation or the use of automatic control systems during the study of covered electrode behavior. The conjugation of different methods like short-circuit time statistical analysis, metallog

6. Desenvolvimento de procedimento utilizando processo de soldagem plasma para confecção de sementes de Iodo125 / Development of a procedure using plasma welding process to produce 125I seeds
The prostate cancer, which is the second cause of death by cancer in men, overcome only by lung cancer, is a problem of public health in Brazil. Brachytherapy is among the possible available treatments for prostate cancer, in which small seeds containing 125I radioisotope are implanted in the prostate. The seed consists of a titanium sealed capsule with 0.8

7. Stainless steel manual metal arc welding fumes in rats.
Forty two male Wistar rats were exposed to manual metal arc (MMA) stainless steel (SS) welding fumes generated by an automatic welding device for "nose-only" exposure. The exposure simulated an actual MMA/SS welding environment as closely as possible. For the retention study, the duration of exposure was one hour per workday for one, two, three, of four week
