In design and fabrication, it is advisable to avoid sharp changes in cross section, such as short radius fillets or undercut that can give rise to _________.
Long-seam welds are particularly susceptible to reheat cracking due to mismatch caused by fit up problems.
In design and fabrication, sharp changes in cross section, such as short radius fillets or undercuts, can lead to stress concentrations. These stress concentrations can become points of weakness susceptible to various types of failure mechanisms, including cracking. Therefore, it is important to avoid such features to maintain the structural integrity and longevity of the component.
In design and fabrication, it is advisable to avoid sharp changes in cross section, such as short radius fillets or undercuts that can give rise to stress concentrations. Long-seam welds are particularly susceptible to mismatch caused by fit-up problems or by “peaking” due to the plate edges not being properly rolled.
