Welding, Repair and Local Post Weld Heat Treatment Residual Stresses
Volume 2: Computer Technology & Bolted Joints; Design & Analysis, 2023Abstract The study presented deals with an industrial case and relates to the calculation of the residual stresses in a butt weld of two shells of large diameter, high thickness and great length constituting part of pressure equipment. After completion of the weld, it can be repaired if unacceptable defects are detected ...

Cranial-Base Repair Using Endoscopic Laser Welding
Otolaryngologic Clinics of North America, 2009As the scope of transnasal cranial-base surgery expands, reconstruction of the complex residual defects remains a challenge. Laser welding is a novel technology that can be performed endoscopically and offers the potential of producing instantaneous, watertight repairs using a chromophore-doped biologic solder.

Performance of repair welds on aged Cr-Mo piping girth welds
Journal of Materials Engineering and Performance, 1999This article documents the results of an industry survey of weld repair practices and describes the results of experimental evaluations performed on service-aged 21/4 Cr-1Mo steel piping using SMAW with both conventional postweld heat treatments and temper bead repair techniques.

Laser welding: An alternative method of venous repair
Journal of Surgical Research, 1986This study compared the histology, biochemistry, tensile strength, and extensibility of Nd:YAG laser-welded and sutured venotomies. Two-centimeter-length bilateral canine femoral or jugular venotomies were evaluated with one vessel (control) closed with interrupted 6-0 polypropylene sutures, and the contralateral vessel (experimental) welded with the ...

Materials at High Temperatures, 2015
Creep strength-enhanced ferritic steels, such as Grade 91, are the preferred material for much of the high-energy boiler tubing and piping components used in modern power generating plants. Weld repair techniques that achieve the necessary performance without the need for high-temperature post weld heat treatment (PWHT) offer particular benefits for ...

Characteristics Evaluation of Weld Metal Zone Welded with Various Repair Welding Filler Metals
Advanced Materials Research, 2013Recently, the fuel oil of diesel engine of marine ships has been changed with heavy oil of low quality as the oil price is getting higher and higher. Therefore, the wear and corrosion against all parts of the engine, such as cylinder liner, piston crown, and spindle and seat ring of exhaust valves has predominantly increased due to its consumption ...

IN WELDING STEEL STRUCTURES REPAIR WELDING AND PROCEDURE
2016The structures which are prepared with high cost welding processes must continue its working lifedespite corossion and static and dynamic loads while doing a lot of functions at the same time. Therefore, extreme stresses which may be occur in time may shorten the life of the welded structure whichhas produced wrongly, also it may cause dramatic life ...
