Journal of the Japan Welding Society, 1959 Experimental studies were made concerning to the annealing and corrosion of the welded P.V.C. plate of 2 nun in thickness. Effects of radiation to the mechanical properties of these materials were also performd.Tensile strength of welded P.V.C. is decreased by the corrosion of H2SO4 HCl and HNO3, and is increased gradually with annealing time.Although ...

Protection of welded joints against corrosion degradation
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013 Welded joints form an integral part of steel constructions. Welded joints are undetachable joints, which are however subjects of corrosion processes. The internal energy increases during the fusion welding especially in the heat affected places around ...
