A New Approach to Simulate HSLA Steel Multipass Welding through Distributed Point Heat Sources Model
Metals, 2018 Mechanical properties of welded joints depend on the way heat flows through the welding passes. In multipass welding the reheating of the heat affected zone (HAZ) can form local brittle zones that need to be delimited for evaluation.

Design of a (mini) wide plate specimen for strain-based weld integrity assessment [PDF]
, 2011 Wide plate tension tests are commonly executed to investigate the integrity of defective welds under a uniaxial load. The specimen can be flat or curved, depending on the geometry from which it has been extracted (plate or pipe).

Effects of hydrogen upon the properties of thermo mechanical controlled process (TMCP) steel [PDF]
, 2016 Research into the effects of hydrogen on the mechanical properties of the material is wide-ranging and time-consuming, since there is no single way of predicting cold cracking that would be applicable to all steel grades.
