Research ArticleOpen accessIn the keywordsA Novel Method to Improve Weld Uniformity by Automatic Control of Current IntensityAbdul Aziz A. Morgan, Fahad A. Al-MufadiThis study aims to develop an automatic arc welding system capable of welding irregular and moving joints which are difficult to weld manually. The motivation of this research comes from the need to produce uniforms weldings on regular and irregular surfaces by automatic means. The system consists of a personal computer equipped with A/D interface card connected to an electric … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 26 Jan 2015 · 7,507 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExperimental Investigation on Micro-Welding of Thin Stainless Steel Sheet by Fiber LaserMohd Idris Shah Ismail, Yasuhiro Okamoto, Akira Okada, Yoshiyuki UnoProblem statement: The miniaturization of components plays an important role for manufacturing in electrical and electronic industries. The joining technology of thin metal sheets has been strongly required. Laser welding with micro-beam and high-speed scanning is a promising solution in micro-welding, because it has high-potential advantages in welding heat sensitive components with precise control of heat input and minimal thermal … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 18 Aug 2011 · 8,996 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRelationship between Nickel Exposure and the Level of Carcinoembryonic Antigen among Welders in an Automotive PlantChiang Lee Juan, Shamsul Bahri Mohd Tamrin, Syazwan Aizat Ismail et al.Background: Study on the effect of nickel exposure in the occupational setting and its association to carcinoembryonic antigen (CEA) had been studied before. Questions were raised whether the result from previous study would also show the same pattern of the urinary nickel concentration in this study. Objective: A cross-sectional study was conducted to determine the association between urine nickel concentration … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 7,636 accessesView PDF Cite
