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 ...

Investigation of the metal/porcelain interface in LASER-welded Ni-Cr-Mo alloy
(2009-07-22)
The interface formed between the metal and the porcelain of laser-welded Ni-Cr-Mo alloy was studied on a metallurgical basis. The characterization was carried out by using optical microscope, electron scan microscopy and ...

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 ...
Mechanical Strength and Analysis of Fracture of Titanium Joining Submitted to Laser and Tig Welding
(Universidade Federal de São Carlos (UFSCar), Dept Engenharia Materials, 2012-11-01)
This study compared the tensile strength and fracture mechanism of tungsten inert gas (TIG) welds in cylindrical rods of commercially pure titanium (cp Ti) with those of laser welds and intact samples. Thirty dumbbell-shaped ...

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 ...
