Elsevier Weld Cracking in Ferrous Alloys (Series in Welding and Other Joining Technologies) (Woodhead Publishing Series in Welding and Other Joining Technologies)

Weld cracks are unacceptable defects that can compromise the integrity of welded structures. Most cracks are the result of solidification, cooling and stresses that develop due to weld shrinkage. Weld cracking can lead to structural failures which at best will require remedial action and at worst can lead to loss of life. All industries that utilise welding can be affected, including nuclear, aerospace, automotive, shipbuilding and civil engineering. This book covers the processes of weld cracking in different ferrous alloys and for different welding technologies. It also covers methods of testing for weld cracks, avoidance and repair. Key Features: reviews the latest developments in the design, evaluation, prevention and repair of weld cracks; assesses recent advances in welding technology, design and material selection; analyses weld crack behaviour, evaluation and repair including environment assisted weld cracking; examines the important area of NDE and quality control. Contents: Part 1 Welding technology and design to prevent weld cracking: Selection of weld-crack resistant stainless steels; Robust welding technologies for ferrous alloys; Design against cracking in ferrous weldments; A discussion of the current procedures for design of welds against fatigue. Part 2 Weld crack behaviour, evaluation and repair: Mechanical behaviour of stainless steel, ferritic steels welds and weld joints; Fracture toughness in the design and operation of ferrous weldments; Testing and evaluation of weld cracking in ferrous alloys; Lessons learnt from failures in ferrous weldments; Cracking in high-performance superduplex stainless steel welds; Weld metal cracking in cellulosic girth welds of pipelines; Repair of weld cracks; Measurement of residual stresses in weld repairs in steels. Part 3 Environment-assisted weld cracking: Corrosion issues in ferrous weldments; Advances in techniques for determination of susceptibility of welds to stress corrosion cracking (KISCC); Less explored types of environment-assisted cracking of welds: Industrial issues and research opportunities.
