weld seam

height of weld seam

weld surrounding area of the base metal, where the microstructure has been altered

in the seam at an angle of 45°

in the heat affected zone at an angle of 45°

breaks the parent metal

weld does not break

in the seam, due to the formation of hardening structures caused by rapid cooling; and presence of internal stresses

in the seam, due to the hydrogen diffusion into the metal

in heat affected zone due to metal's shrinkage and presence of internal stresses

in the seam, due to metals low deformability in semi-solid state and the deformations caused by shrinkage.
