1. Investigation on the Wear Properties of Ti/TiC/TiN Composite Coatings Prepared by Powder Cored Wires Through TIG Method at Nitrogen Atmosphere on Titanium Substrate
In this present study, Tungsten Inert Gas (TIG) welding and powder filled cored wires with nitrogen shielding gas were utilized to produce TiC and TiN surface composite coatings on the titanium (Ti) sheet substrate. The TIG procedure was done at same welding parameters for all of prepared samples. Phase analysis and microstructures were done by X-ray Diffrac

2. Microstructure and Abrasion Resistance of Fe-Cr-C and Fe-Cr-C-Nb Hardfacing Alloys Deposited by S-FCAW and Cold Solid Wires
Abstract This work assesses the wear resistance behavior of different high Cr and Nb alloyed hardfacing deposits carried out by Self-shielded Flux Cored Arc Welding, considering the resulting microstructures as base for the analysis. To obtain non-commercial alloys, an “in-situ” technique was employed with addition of cold wire into the weld pool. Six co

3. Influence of Heat Input and Filler Metal on Mechanical Properties and Microstructure of Microalloyed High Strength Steel Welded by FCAW
AbstractCurrently, microalloyed high strength steels are being widely used to replace C and C-Mn steels for their advantages in terms of mechanical properties, corrosion resistance and weldability, allowing weight reduction of vehicles and structures without impairing their strength. When these steels are welded, the welding heat cycle causes microstructural

4. Aplicação de revestimento duro utilizando o processo arame tubular com e sem adição de arame não energizado para diferentes tipos de consumíveis / Hardfacing application using the FCAW process with and without not-energized wire addition for different kind of consumables
O cultivo de cana-de-açúcar é uma das maiores atividades agropecuárias do Brasil proporcionando um forte mercado de produção e exportação de etanol e açúcar. Um dos fatores que afetam os custos do processo da indústria sucroalcooleira é a manutenção dos equipamentos afetados por danos relacionados à perda de metal (massa) por mecanismos de des

5. Mapeamento do processo mecanizado de soldagem unilateral FCAW com backing cerâmico aplicável no passe de raiz em aço carbono
This work aims to evaluate one-sided welding automatic using the flux cored arc welding process with ceramic backing in the root bead. The tests were performed using a KUKA KR-16, robot for welding in the flat position. The wire is the AWS A5.20-79 E 71T-1, with 1.2 mm diameter, V-groove butt joints were design to be used in steel plate ASTM A-36. The proces

6. Aplicação de ensaio de impacto Charpy instrumentado no estudo da tenacidade à fratura dinâmica nas soldas a arco submerso em aços para caldeiras / Instrumented Charpy impact test application in the dynamic fracture toughness study by submerged arc welds at steel for boilers
A utilização do eletrodo tubular no processo de soldagem a arco submerso leva a um aumento na produtividade com um custo relativamente baixo, pois não requer investimentos complementares em equipamentos. A mudança do eletrodo sólido para o tubular acarreta variações microestruturais no metal de solda que influenciam as propriedades mecânicas, tais co

7. Efeito do Tipo de GÃs de ProteÃÃo Sobre o Desempenho do Arame Tubular AWS E71T-1, Utilizando Processo Convencional e Pulsado / The effect of the shielding gas type on performance of the AWS E71T-1 flux cored wire using the conventional and the pulsed process
O arame tubular AWS E71T-1 tem sido utilizado, na grande maioria das aplicaÃÃes, com CO2 e argÃnio. No entanto, para esta mistura de gÃs, as informaÃÃes nÃo foram levantadas, de forma suficiente, com relaÃÃo ao desempenho operacional do arame. Sabe-se que o tipo de gÃs afeta tambÃm a transferÃncia metÃlica, o comportamento do arco, a geometria d

8. Welding current effect on diffusible hydrogen content in flux cored arc weld metal
The application of flux cored arc welding (FCAW) has increased in manufacturing and fabrication. Even though FCAW is well known for its good capability in producing quality welds, few reports have been published on the cause of the relatively high diffusible hydrogen content in the weld metal and its relation with the ingredients used in the wire production
