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 ...

Fracture resistance of flash welded and laser welded butt joints in a microalloyed HSLA steel
(2017-01-01)
High-strength, low-alloy (HSLA) steels are widely used in the automotive and oil industries due to their good mechanical properties and weldability. The selection of the welding process depends on several factors, including ...
Pulsed Nd:YAG laser welding of UNS S 32205 duplex stainless steel
(2016-01-01)
This paper reports an experimental study of laser welding on duplex stainless steel UNS S32205 employed in the oil and natural gas industries. A pulsed Nd:YAG laser was used to weld the specimens. Bead on plate condition ...
Fatigue Crack Growth Investigation on a Maintenance Welding Repair Applied on a High Responsibility Airframe
(Elsevier B.V., 2014-01-01)
Fatigue crack usually initiates at welded joints of structural elements. For a high-responsibility aeronautic component, called Motor-Cradle - critical to the flight safety -, successive weld repairs are carried out toward ...
Comparison between autogenous welding and with addition of nickel on nd:yag pulsed laser welded UNS s32750 duplex stainless steel
(2019-01-01)
Duplex stainless steels (DSS) have a biphasic microstructure with equal proportions of austenite and ferrite, which gives them excellent mechanical strength and corrosion resistance compared to austenitic stainless steels. ...
Corrosion assessment of ASME qualified welding procedures for grade 2101 lean duplex stainless steel
(2019-01-01)
ASME qualified welding procedures do not guarantee suitable corrosion and passivation properties for lean duplex stainless steel welds. An evaluation of two ASME qualified welding procedures to optimize the corrosion ...
