Schematic illustration of the positions where the photographs below were taken. The HAZ is the heat-affected zone.
Montage of weld
2.4 kJ/mm heat input. Montage with weld metal on the right and heat-affected zone on the left. The photographs are taken along a horizontal traverse which does not include any weld-bead overlap, as illustrated in the schematic drawing. Higher magnification snapshots follow.
Martensite, HAZ
2.4 kJ/mm heat input. The photograph was taken at position 8 in the heat affected zone (HAZ), along a horizontal traverse which does not include any weld-bead overlap, as illustrated in the schematic drawing.
Martensite, HAZ
2.4 kJ/mm heat input. The photograph was taken at position 7 in the heat affected zone (HAZ), along a horizontal traverse which does not include any weld-bead overlap, as illustrated in the schematic drawing.
Martensite, HAZ
2.4 kJ/mm heat input. The photograph was taken at position 6 in the heat affected zone (HAZ), along a horizontal traverse which does not include any weld-bead overlap, as illustrated in the schematic drawing.
Martensite, HAZ
2.4 kJ/mm heat input. The photograph was taken at position 5 in the heat affected zone (HAZ), along a horizontal traverse which does not include any weld-bead overlap, as illustrated in the schematic drawing.

Martensite, fusion surface
2.4 kJ/mm heat input. The photograph was taken at position 2 at the fusion line, along a horizontal traverse which does not include any weld-bead overlap, as illustrated in the schematic drawing.
Martensite, fusion line
2.4 kJ/mm heat input. The photograph was taken at position 1 including the fusion line, along a horizontal traverse which does not include any weld-bead overlap, as illustrated in the schematic drawing.
Montage of weld
2.4 kJ/mm heat input. Montage with weld metal on the right and heat-affected zone on the left. The photographs are taken along a horizontal traverse which covers the 'recrystallised' region where weld-beads overlap, as illustrated in the schematic drawing. Higher magnification snapshots follow
