Top 10 Common Sense Fallacies in Maintenance
#5: Getting grounded
When performing Maintenance Welding you can connect your ground lead anywhere as long as there is metal contact to the welded area (through overhead steel structure, etc). FALSE, Electrical current will flow through the path of least resistance and many times this path could be through electrical/electronic components, bearings, etc thus creating unknown failures for a later date.
Solution: A Welding Ground Clamp should be connected, if possible, within 6-10 inches of the welded area. Maintenance supervisor warning: if your welding ground lead is shorter than your welding electrode lead then you may be experiencing what is called “self induced failures”.

Maintenance Tip
Standing Work Orders
Standing work orders should be opened and closed on a monthly basis. It is important to audit what types of maintenance work is being charged to these work orders and if those charges are appropriate. Without audits and timely closure, standing work orders become a black hole for equipment cost and history.
