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 utilize 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.
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
Mechanical behaviour of stainless steel, ferritic steel welds and weld joints
Fracture toughness in the design and operation of ferrous weldments
Testing and evaluation of weld cracking in ferrous alloys
Lessons leat 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
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
