ELECTRODOS STORAGE RECOMMENDATIONS:
 

Stick electrodes are a common filler metal choice for equipment repairs that occur in the field, as they are lightweight and do not require a shielding gas. They are also available in a variety of alloys, making them usable on many types of materials. Stick electrodes are best suited for smaller repairs due to the need for frequent electrode change out.

Moisture, in particular, is the biggest enemy of stick electrodes. Not only can it cause porosity and hydrogen-induced cracking, but also it can result in costly downtime for rework associated with these defects.

Never leave a can or carton of stick electrodes open in the shop or in the field, especially if you are using a low-hydrogen product. Instead, you should store your stick electrodes as recommended by the manufacturer, which may require the product to be placed in a storage oven designed for this purpose. Filler manufacturers provide recommendations for the best storage temperature for each of their products. For example, a stick electrode classified as American Welding Society (AWS) E7018-1 H4R (a commonly designated low-hydrogen product) may have a storage temperature of 220- to 350-degrees Fahrenheit. This temperature keeps the stick electrode at its optimum operating condition and also ensures it provides the low-hydrogen weld deposit indicated by its AWS classification — in this case, 4 ml. per 100 grams (indicated by the H4). Check with your filler metal manufacturer for proper storage temperatures for your stick electrodes or consult the original package for information.

When possible, select stick electrode packages that offer good moisture resistance. Options include wax coated cartons or re-sealable plastic packages. Remember to close the package after you retrieve your stick electrode. Also note, for critical repairs, such as those involving a load-bearing joint, you may have specific welding procedures or codes that require you to discard your stick electrodes after a given period of time—regardless of the type of package you have or if you’ve stored it properly in an oven.

Most filler metal manufacturers offer information on the original packaging for reconditioning stick electrodes should they become exposed to moisture (see Figure 1 for examples). Reconditioning involves placing the exposed stick electrodes in an oven at a given temperature for a specified period of time. In the example of the AWS E7018-1 H4R stick electrode, this product might have a reconditioning recommendation of one hour at 575 degrees Fahrenheit. Again, be certain to check your particular stick electrode package, or call the manufacturer for the proper reconditioning information.
