Effects of several TIG weld repairs on the axial fatigue strength of AISI 4130 aeronautical steel-welded joints
(Wiley-Blackwell, 2012-03-01)
Welded joints of airframes critical to the flight-safety are commonly repair welded during its operational live. In this study, the effect of up to three weld repairs by gas tungsten arc welding (GTAW) on the axial fatigue ...
Aplicação de cavacos de titânio para produção de revestimentos resistentes ao desgaste
(Associação Brasileira de Soldagem, 2014-09-01)
Equipments of the sugar-cane plants and mineral extraction are submitted to severe abrasive wear conditions. Welded hardfacing are usually applied to repair that kind of damage where commercial chromium/carbon-rich welding ...
ASTM A923-Practice A application to identify intermetallic phases in a UNS S32750 superduplex welded joint
(ESCOLA DE MINAS, 2010)
Duplex and superduplex stainless steels present superior mechanical and corrosion properties when compared to usual stainless steels. This superiority is based on chemical composition when in a balanced microstructure ...
Reciclagem de cavacos de titânio para a deposição de revestimentos duros por soldagem
(2015-01-01)
Titanium element is a noble metal and owns excellent biomechanical properties. The necessity for utilization dental implants fabricated with titanium alloys have caused an increased in generation of residue as a result of ...
Characterization of titanium welded joints by the orbital gas tungsten arc welding process for aerospace application
(Departamento de Ciência e Tecnologia Aeroespacial, 2010)
In this work, three welding programs for orbital gas tungsten arc welding (GTAW), previously developed, were used, using pulsed current and increasing speed (#A), constant current (#B) and pulsed current and decreasing ...
Repair Welding Effects on the Bending Fatigue Strength of AISI 4130 Aeronautical Steel used in a Critical to the Flight-Safety Structure
(Trans Tech Publications Ltd, 2010-01-01)
The aim of this study was to analyze the effect of successive TIG (tungsten inert gas) welding repairs on the reverse bending fatigue strength of AISI 4130 steel, which is widely used in components critical to the ...
Aplicação da norma astm A923-Prática a para identificação de fases intermetálicas em junta soldada de aço inoxidável superduplex UNS 32750
(Escola de Minas, 2010)
Os aços inoxidáveis duplex e superduplex apresentam propriedades superiores aos aços inoxidáveis convencionais. Essa superioridade é baseada na composição química e em uma microestrutura balanceada (aproximadamente 50% de ...
