This book was released on 1996-09-01 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fundamental factors affecting the impact toughness of four gas metal arc welds (GMAW) made on HSLA-100 base plate using a newly developed steel weld wire were studied. The weld metal analysis included chemistry, mechanical testing (hardness, CVN/FATT), as well as optical, scanning and transmission electron microscopy. Studies of inclusion composition using energy dispersive x- ray (EDX), and electron energy loss spectroscopy (EELS) in the transmission electron microscope were also performed. It was found that increasing oxygen content of the weld metal (due to increased oxygen in the shielding gas) led to increased non-metallic inclusion size and volume fraction; which in turn, led to both decreasing strength and toughness. The strength was lowered because increasing oxygen in the shielding gas led to increased 'consumption' of strengthening alloys such as carbon, manganese and silicon. The toughness was compromised by the increasing size and number of oxide inclusions as these provide sites for void formation and subsequent fracture.

This book was released on 1999-12-01 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: The factors that affect strength and toughness often ultra-low carbon steel weld samples (HSLA-80 and HSLA-100), welded using the gas metal arc welding (GMAW) process and new ultra-low carbon consumable electrodes, were studied. The analysis was confined only to the weld metal, and the base metal was not considered. Analysis methods included optical microscopy, scanning electron microscopy, and transmission electron microscopy. Energy dispersive x- ray analysis was performed in the transmission electron microscope to analyze the chemical composition of non-metallic inclusions. The microstructure was found to be primarily granular ferrite with some primary ferrite, bainite, and martensite. Very little acicular ferrite was found (

Available in PDF, EPUB and Kindle. Book excerpt: This report details a metallurgical analysis which identifies the factors affecting the strength and toughness behavior of newly developed low carbon welding consumables. It was found that the 50% transformation temperature (T50) was a good indicator of the microstructure type and was successfully correlated to weld deposit strength. Other factors responsible for strength development were prior austenite grain width (gamma sub gw), cooling rate, muitipass reheating, carbon content and oxygen. The factors responsible for toughness development.

This book was released on 1994 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted to evaluate the effect of weld cooling rate on the strength of autogenous GTAW deposited weld metal. The basic weld metal composition was based on a low carbon bainite metallurgical system. The weld metal yield strength goal was 130 ksi, needed to surpass the current HY-13O weld metal requirements. Vacuum Induction Melted (VIM) heats of steel were produced and processed into 3/4' thickness plates. The autogenous gas tungsten are welds (GTAW) on the parent steel plates were produced under two different heat input conditions. Tensile specimens were produced from the weldments; specimens from certain heats were subjected to gleeble thermal simulations of multi-pass welding conditions using the Gleeble 1500. All specimens were then evaluated for yield and ultimate tensile strength. From the data presented, it was found that the experimental compositions studied were less sensitive to cooling rate than current HY-130 welding consumables. The compositions tested approached the target yield strength of 130 ksi, but further work is necessary in this area.

Book Synopsis Process Variables And Post Weld Heat Treatment Effects On Steel Weld by : Oluyemi Olawale
Download or read book Process Variables And Post Weld Heat Treatment Effects On Steel Weld written by Oluyemi Olawale and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph presents the outcome of our investigation that was conducted to correlate process variables in shielded metal-arc welding and post weld heat treatment on some mechanical properties of low carbon steel weld. From the results obtained we observed that welding current and post weld heat treatment temperatures influences the tensile strength, impact strength and hardness of welded low carbon steel. As the welding current increases the hardness and strength increases but impact strength reduces, while hardness and strength continuously reduces but impact strength increases as post weld heat treatment temperatures increases. This outcome will help to eliminate much of the "guess work" often employed by welders to specify welding parameters and help them to properly select them for a given task to provide a good weld quality. With this finding welder can now adequately select welding currents and post weld heat treatment temperatures for low carbon steel that will yield quality weld in shielded metal-arc welding without guess work.

Available in PDF, EPUB and Kindle. Book excerpt: The book describes the results of over 20 years research completed this year at one of the world's premier consumable manufacturers and aimed at improving the properties of MMA electrodes for high quality applications. It examines the influence of some 17 elements and welding variables on the composition, microstructure and mechanical properties of the resulting weld metal. The often complex relationships discovered are sufficient to give a good understanding of the properties of weld metals produced by other arc welding processes.
