In the present study, bead-on-plate specimens of 1-mm sheets of austenitic and duplex stainless steels were fabricated by laser penetration welding with a 2.5-kW CW Nd:YAG laser. The galvanic corrosion behavior of laser-weldment (LW) against as-received (AR) specimens with an area rato of 1:1 in 3.5% NaCL solution was studied by means of a zero-resistance ammeter. The free corrosion potentials of as-received specimens were found to be considerably higher than those of laser weldments, indicating that the weldments are more active and always act as anodes. The ranking of galvanic current densities (IG) of the couples in ascending order is: AR S31603-LW S31603 , AR S31803-LW S31803 , AR S32760-LW S32760 , AR S30400-LW S30400. For the galvanic couple between AR S30400 and LW S30400, the IG is the highest (78.6 nA/cm2) because large amount of δ-ferrite in the weld zone acts as active sites. On the other hand, the IG of the galvanic couple between AR S31603 and LW S31603 is the lowest (-26 nA/cm2) ...

Our family hobby was rock hunting, says Ron Wold, who grew up in Beaverton and majored in geology at Amherst. He got a masters degree at the University of Montana, then came to Eugene to pursue a Ph.D. After two years, I got a job as a geologist with the Bureau of Land Management, says Wold, who eventually became a realty specialist in the agencys Eugene office. I managed right-of-way agreements on 320,000 acres. After 30 years of service, he retired in 2004 at age 56. Though he knew at an early age that he was attracted to men, Wold took a conventional path, married a hometown Oregon girl and had a son, Eric. The marriage lasted five years. Two years later, he met Ken Hinds, an RN at Sacred Heart. Weve been together 36 years next month, he notes. He helped raise my son. Wold became active in politics shortly after retirement, in the failed 2004 effort to defeat Measure 36, banning gay marriage. He took part in the 2008 and 2012 Obama campaigns with his own personal project, a ...

It has long been non-destructively evaluated on weld joints of various pipes which are indispensable to most of industrial structures. Ultrasound evaluation has been used to detect flaws in welding joints, but some technical deficiencies still remain. Especially, ultrasound imaging on weld of elbow pipes has many challenging issues due to varying surface along circumferential direction. Conventional ultrasound imaging has particularly focused on ultrasonic wave propagation based on ray theory. This confines the incident angle and the position of an array transducer as well. Total focusing method (TFM), however, can provide not only high resolution images but also flexibility that enables to use ultrasonic waves to every direction that they can reach. This leads us to develop a method to get images of weld zone from an elbow part that curves. It is inevitable of each ultrasonic wave from the array transducer to transmit through different media and to be reflected from the boundary with angles ...

Materials have gotten stronger, but welds havent. We can design metals with intricate microstructures, but we destroy the microstructure when we weld, he said.. With our method, materials are shaped and bonded together at the same time, and they actually get stronger.. Daehn explained the new process in a keynote address at the Materials Science & Technology 2015 meeting recently in Columbus.. In a common technique called resistance spot welding, manufacturers pass a high electrical current through pieces of metal, so that the metals natural electrical resistance generates heat that partially melts them together and forms a weld. The drawbacks: generating high currents consumes a lot of energy, and the melted portions of metal are never as strong afterward as they were before.. Over the last decade, Daehn and his team have been trying to find ways around those problems. Theyve amassed more than half a dozen patents on a system called vaporized foil actuator (VFA) welding.. In VFA, a ...

A system and method have been provided for removing high lead content solder balls from the surface of a circuit package for the purpose of rework. The invention is applicable to ball grid array (BGA), C4 balls, chip scale balls, and flip chip bumps. Advantageously, the room temperature solder ball rework procedure minimizes damage to the circuit package. Specifically, a thin-film stainless steel mask with openings to expose the solder balls, is formed over the circuit package, and the solder balls are removed in a shearing or grinding operation, leaving a solder ball residue. Then, a conventional thick mask film is formed and a solder paste is deposited to fill the apertures. The solder ball residue forms a wettable surface for the low temperature attachment of new solder balls.

Microstructural Development in Friction Stir Welding R.W. Fonda,1 J.F. Bingert,2 and K.J. Colligan3 1 Materials Science and Technology Division 2 Los Alamos National Laboratory 3 Concurrent Technologies Corporation Introduction: Friction stir welding (FSW) is a relatively new technique for joining metals. It uses a rotating tool to deform (stir) the surrounding material together without any melting (Fig. 8). Although FSW was only developed in 1991,1 it is already experiencing a rapid growth in applications because of its ability to consistently produce high quality welds with low distortion, even in materials considered unweldable by conventional techniques. In addition, the accompanying reductions in weld inspection and re-weld procedures can also provide significant cost benefits. However, despite this considerable interest in FSW, the microstructural evolutions occurring during FSW are still not well understood. Conventional studies typically examine only sections of the deposited weld, ...

PROPOSED METHOD. The scarcity of skilled welders means that the development of additional factors, which will allow for variable artisan skills, should be possible. The objective of this study is therefore to develop a table of weld resistance factors, classified according to the grade of the welder. This is done to incorporate different skills into the design procedure, allowing the engineer freedom to assess the availability of welding skills and to specify connection details accordingly. Welders were classified into five groups, with Grades 1 and 5 being the lowest and highest grades respectively. These grades are a function of the training and experience of the welder. Welders in different grades will achieve different weld qualities and strengths. This subject is relevant to conditions in South Africa today when it may be desired to use welders who are below the standard normally required. The purpose of this research is therefore to determine what adjustments, if any, should be made to the ...
