Basic Understanding of Weld Corrosion - ASM International

Microstructural Gradients.On a fine scale, microstructural gradients exist within the HAZ due to different time-temperature cycles experienced by each element of material. Gradi-ents on a similar scale exist within solidified multi-pass weld metal due to bead-to-bead vari-ations in thermal experience. Compositional

POLYMERS • A polymer is a macromolecule (long molecules) built of small covalently bonded units called monomers (“mer” from the Greek word meros meaning part). • These small units are repeated throughout the macromolecule chain. • The macromolecules are bonded together by weak Van der Waals
