Behaviour of welded and brazed joints in galvanized steels in a corrosive environment

Abstract

Investigations were carried out into the behaviour in a corrosive medium of joints in galvanized steels produced by arc welding and brazing without removal of the coating using welding materials based on iron, copper, zinc and aluminium. The topography of the electrode potentials and galvanic currents on the surface of the joints, coated with a thin layer of the electrolyte, is determined. The maximum width of the damaged coating in relation to the joint, ensuring efficient anodic shielding, is determined. The corrosion resistance of the joints is evaluated.

Evaluation of anticorrosive properties of welded junctions of pipes and profiles made of a galvanized strip on a continuous electric-weld pipe mill

“…1 приведен общий характер разрушения цинкового покрытия на внутренней поверхности трубы в зоне сварного соединения. Диаграмма распределения температуры нагрева металла в направлении поперечного сечения от оси шва определена условно по параметрам повреждения покрытия и зоны термического влияния сварного соединения [4].…”

Development of Predicted Stress and Strain during Conventional and after Mitigation of Welded Aluminium-Manganese Alloy

“…The reduction in thickness will need to effective solutions for residual stress control during welding. The negative influence of welding stresses and deformations on the welded structure have been discussed by many researchers [1][2][3][4][5]. In the past decades, efforts have been made and progress has been achieved in controlling stress and distortion problems [6][7][8][9][10][11].…”
