Abstract: The present invention describes the connecting of a corrodible material (100, 105) with a non-corrodible material (110, 115) by electron beam welding so that the corrodible (100, 105) material is not affected by non-corrodible material (110, 115) during the welding process. Employing an electron beam welding process not only minimizes unintended alloying of the corrodible element (100, 105) but also minimizes the width of the weld heat affected and fusion zones. This fabrication method is necessary to ensure that the corrodible element (100, 105) faithfully replicates the wastage of the subject metal.
