Stray current testing procedure
WebStray current corrosion occurs when metal with an electrical current flowing into it is immersed in water that is grounded (such as in any lake, river, or ocean). The current can leave the metal and flow through the water to ground. This will cause rapid corrosion of the metal at the point where the current leaves. Stray direct current (or ...

Web4 Feb 2024 · Wow! This is not even close to the procedure for determining the source of stray current. Read Nigel Calder's Boatowner's Mechanical and Electrical Manual for a very detailed step by step procedure. It is not a reference cathode, it is a reference anode. WebMMA and TIG processes can be either alternating current (AC) or direct current (DC) whilst MIG is usually only operated with DC. As arc processes need a large current (up to 500 A) but at a relatively low arc voltage (10 to 40V),the high voltage mains supply (230 or 400V) must be reduced.

WebThe stray current density on the surface of Steel Bar 1 is higher than on the Steel Bar 2 in both Case 1 and Case 2. This is clearly indicated in Figures 7 and 8 (Case 1) and Figure 8 and 10 (Case 2). Therefore, it is apparent that the effect of stray current corrosion on Steel Bar 1 is greater than that on Steel Bar 2 in the present study.
