Executed destructive tests were tensile testing, hardness testing and metallographic analysis, allowing us to determine several mechanical properties of the welded joints, such as ultimate tensile strength, strain, hardness profile throughout the welded joint, and changes in the material’s microstructure.
1 gru 2022 · Current work presents a review of various filler materials (electrodes) used to weld ductile cast iron using two common industrial welding processes, namely, shielded metal arc welding...
Our results revealed that the weldability of ductile cast iron can be enhanced by performing laser surface pretreatment to sublimate graphite nodules. Microhardness at the interface of the...
The present work analyses the strength and microstuctural variations of ductile cast iron welded by means of the TIG technique, without heat treatment and using different filler materials (pearlitic malleable cast iron, Fe-Ni alloy and bronze and manganese alloy).
This article aims at measuring and comparing the fatigue strength with fully reversed push-pull tests in the case of two different cast irons: ductile and vermicular. Spheroidal Graphite Iron (SGI), also known as ductile cast iron, is nowadays used in a very large variety of applications.
14 lip 2019 · Abstract. The main advantage of welding cast iron is to recover parts by repairing defects induced by casting processes (porosities, etc.), before they enter their working cycle, as well as repair cracks or fractures when already in service.
24 lip 2024 · For the spheroidal graphite cast iron materials, also known as ductile cast iron (DCI), EN-GJS-400-18-LT and EN-GJS-450-18, different welding procedures were examined for potential repair welding. A repair weld was performed on thick cast iron plates using the optimum procedure in each case.
