Intro to Welding • A weld is made when separate pieces of material to be joined combine and form one piece when heated to a temperature high enough to cause softening or melting. The precast elements are joined by welding the projected reinforcement bars (dowels) and casting the concrete in place. The boundaries more or less fade at the weld, and amalgamated crystals develop across them. Charts and graphs that support statistical analyses are illustrated in appendices as referenced in the body of the report. Laser Welding-Basics • Laser welding is a non-contact process that requires access to the weld zone from one side of the parts being welded • The weld is formed as the intense laser light rapidly heats the material-typically calculated in milli-seconds. Hyperbaric welding can either take place wet in the water itself or dry inside a specially constructed positive pressure enclosure and hence a dry environment. 1 Material Properties of Plastics 1.1 Formation and Structure The basic structure of plastics (or polymers) is given by macromolecule chains, formulated from monomer units by chemical reactions.
