An experimental study was conducted into whether a workpiece reaches the lower bounds of melting temperature to trigger liquation when friction stir welded. BY G. Cao and S. Kou Published January 2005 A visual imaging system provides feedback on weld shape for controlling welding on plates with varied root openings. BY G. J. Zhang et al. Published January 2005 A test was devised to determine basic, independent machine parameters to help in the development of a model for predicting the mechanical dynamics of a resistance welding machine. BY P. Wu et al. Published January 2005 An increase in carbon content proved beneficial in reducing thin plate distortion caused by welding. BY M. P. Lightfoot et al. Published February 2005 A small welding hood that completely covered the weld area helped minimize fume emissions. BY N. Turkem et al. Published February 2005 A small amount of zinc in the filler metal composition was found to be a key ingredient for high joint strength. BY T. Watanabe et al. Published March 2005 The strength of a ceramic-metal interface was improved with the addition of a copper film interlayer. BY J. T. McKeown et al. Published March 2005 As molybdenum increased, hardness, yield, and tensile strengths increased for high-strength SMAW electrode weld metal. BY E. Surian et al. Published April 2005 An investigation showed high-Si, Al-Si casting alloys could backfill and heal liquation cracks in welds no matter which filler metal was used. BY G. Cao and S. Kou Published April 2005 A parametric study was carried out on a Gleeble® machine to evaluate the influence of pressure, temperature, and metal properties on resistance welding. BY Q. Song et al. Published May 2005 A parametric study was carried out on a Gleeble® machine to evaluate the influence of pressure, temperature, and metal properties on resistance welding. BY Q. Song et al. Published May 2005 Airborne particle size proves an important factor in determining welding fume toxicity. BY N. T. Jenkins and T. W. Eagar Published June 2005 A means of determining tungsten electrode service life under hyperbaric conditions is presented. BY H. Ozden and K. T.

DebRoy Published July 2005 To improve the reliability of heat transfer and fluid flow prediction calculations, optimized values for process variables were factored into the model. BY A. De and T. DebRoy Published July 2005 A controlled random search can determine the nearoptimal settings for weld process parameters using a small number of experiments. BY D. Kim et al. Published August 2005 A constraints-based modeling approach reduced the risks inherent in developing a high-performance welding electrode specification for U.S. Navy applications. BY K. Sampath Published August 2005 Different shielding gases, welding position, number of weld passes, and arc energy were all studied to assess their influence on the all-weld-metal properties of a metal cored filler metal. BY N. M. Ramini De Rissone et al. Published September 2005 A method was developed to estimate the cooling rate of a welded section based on applying a weighting factor to the Rosenthal analytical solutions for thick and thin plates. BY K. Poorhaydari et al. Published October 2005 Impactor separation of welding fumes showed the welding process determined particle size distribution. BY N. T. Jenkins et al. Published October 2005 Mathematical models were developed to correlate out-of-plane distortion with process variables. BY V. Vel Murugan and V. Gunaraj Published November 2005 Its high strength and light weight make DP-600 very attractive for auto bodies, but wide acceptance will depend on the proof of spot weld integrity. BY M. Marya and X. Q. Gayden Published November 2005 Fatigue life and fatigue limit were treated as random variables in this statistical model. BY V. Vel Murugan and V. Gunaraj Published December 2005 The integral of specific current action was used to quantitatively explain the mechanism of spatter production. BY S. K. Kang and S. J.
