Stick electrodes also require proper handling and storage on the jobsite if you are to achieve proper weld quality, maintain compliance with the specified welding parameter, and eliminate unnecessary downtime.

Without question, moisture is the number one enemy of stick electrodes—it can cause hydrogen induced-cracking, porosity and a host of other weld discontinuities that require rework. Depending on the type, stick electrodes often must be stored in a holding oven at a specific temperature to protect them from moisture. In some cases, a specific welding procedure or code even dictates how long a package of stick electrodes can remain open before it must be discarded—regardless of whether or not it has been stored in an oven.

Not surprisingly, leaving a package (can or carton) of stick electrodes open and/or storing it improperly during or after the workday are the biggest mistakes anyone can make on the jobsite, especially with low-hydrogen products. Remember to always follow the welding code specifications for the job, as well as the filler metal manufacturer’s instructions for the particular stick electrode. Proper oven storage or holding temperatures are critical. Also, look for packaging options that provide greater moisture resistance, such as a wax-coated carton or plastic package, and always close the package after retrieving an electrode.

In the event that stick electrodes have been exposed to moisture, follow the recommended procedure for reconditioning them. Reconditioning involves placing the damaged electrodes in an oven at a given temperature for a specified period of time. Instructions for reconditioning are included with the original stick electrode package, or can be determined by contacting a trusted welding supply distributor. Note: welding wires never should be reconditioned.

A small price to pay
Most people would agree that filler metals are only one of many concerns to have on a jobsite. Worker safety, compliance to the job specifications, material handling, and other jobsite issues certainly take precedence. Still, the goal of any job is to complete it correctly, on time, under budget, and with the greatest amount of efficiency. Properly handling and storing filler meals can be a simple way to help achieve these goals. It just takes a little time and know-how to yield positive results—both in cost savings and productivity.
