Abstract: A method for manufacturing an element (8) of a modular scaffolding system, comprising: providing an at least partly galvanized pipe part (10) having a first end (12) and a second end; providing an at least partly galvanized first connection head (40) which is designed to be connected to the first end (12) of the pipe part (10); forming, through welding, a weld (24) which connects the first end (12) of the pipe part (10) to the first connection head (40), the weld (24) comprising an internal weld surface (24b) and an external weld surface (24a), which internal weld surface is proximal to the pipe part (10) and/or the connection head (40), and which external weld surface is proximal to an outside environment (60) of the pipe part (10) and the connecting head (40).; and covering the external weld surface with a protective layer, such that the external weld surface is screened off from the outside environment (60).
