DOWNLOAD EBOOKKey articles from over 10 separate ASM publications are brought together as a practical reference on weld integrity crack prevention. This book thoroughly covers the essentials of weld solidification and cracking, weldability and material selection, process control and heat treatment, failure analysis, and fatigue and fracture mechanics weldments. Contents also include an appendix for quick reference of tabular data on weldability of alloys, process selection, recommended interpass and heat treatment temperatures, and qualification codes and standards.

DOWNLOAD EBOOKThis book is intended to guide practicing structural engineers familiar with ear lier ACI building codes into more profitable routine designs with the ACI 1995 Building Code (ACI 318-95). Each new ACI Building Code expresses the latest knowledge of reinforced concrete in legal language for safe design application. Beginning in 1956 with the introduction of ultimate strength design, each new code offered better uti lization of high-strength reinforcement and the compressive strength of the con crete itself. Each new code thus permitted more economy as to construction material, but achieved it through more detailed and complicated design calcula tions. In addition to competition requiring independent structural engineers to follow the latest code for economy, it created a professional obligation to fol low the latest code for accepted levels of structural safety. The increasing complexity of codes has encouraged the use of computers for design and has stimulated the development of computer-based handbooks. Before computer software can be successfully used in the structural design of buildings, preliminary sizes of structural elements must be established from handbook tables, estimates, or experienced first guesses for input into the com puter.

DOWNLOAD EBOOKThis effort sought to determine the validity of carbon equivalent formulae to predict weldability of low carbon microalloyed steels. The HAZ of a range of steels was characterized (HSLA 80-130, HY 130, DQ and AC types) and Yuriokas formula was found to be the most accurate in predicting HAZ hardness. The CE1 carbon equivalent formula was also found to most accurately predict hardenability except that the effect of copper is not linear above 0.5%. The hydrogen sensitivity was evaluated by the Implant, Battelle and UT-Mod Hydrogen Sensitivity tests at two hydrogen levels. The lower critical stress in the implant test was used to define the critical preheat temperatures for steels evaluated. The HLSA 80 type materials may require a preheat of 150 F under highly restrained conditions with hydrogen present. HLSA 130 was found to be superior to HY 130 in regard to hydrogen cracking sensitivity. The high strength steels can be ranked in the order of increasing preheat cracking as: HSLA 100-- HSLA 130--DQ 125--HY 130 DQ 80 and AC 50 steels responded well to testing at high hydrogen levels (20ppm) and ambient temperature preheat. A soft zone was found in the HAZ of the HSLA, DQ and AC steels which was a function of weld heat input. The soft zone in the copper bearing HLSA steel could be eliminated by PWHT. A probe study showed that the HSLA steel is similar to A 1710 grades with regard to PWHT/Reheat cracking and that the HAZ toughness decrease is also similar to the A 710 grades.
