Why Stainless Welds Lose Corrosion Resistance
Stainless steel can lose corrosion resistance after welding when the weld area is overheated, not cleaned properly, or matched with the wrong filler. The base metal may still be stainless, but the…

Common 70 Series Stick Electrodes: 7014 vs 7018 vs 7024
The E7014, E7018, and E7024 stick electrodes are all part of the AWS E70XX family, meaning they are designed to produce welds with approximately 70,000 PSI tensile strength. While they share similar…

6011 Rod Penetration Problems Troubleshooting: Polarity, Amperage, Arc Length, and Technique Fixes
6011 rod penetration problems usually come from low amperage, wrong polarity, weak AC output, long arc length, poor work lead connection, fast travel speed, electrode diameter mismatch, or poor joint preparation. E6011…

Stick Welding Porosity Troubleshooting: Pinholes, Wormholes, Moisture, Arc Length, and Electrode Checks
Stick welding porosity usually comes from gas trapped in the weld metal before the puddle freezes. With SMAW, start with the electrode, base metal, arc length, amperage, polarity, and technique before blaming…

6010 vs 7018 Rod Selection Guide: When to Use Each Stick Electrode
Use 6010 when the weld needs deep penetration, fast-freeze puddle control, open-root tie-in, or tolerance for less-than-perfect steel. Use 7018 when the weld needs low-hydrogen deposit control, higher tensile classification, smoother fill…

Stick Electrode Sticking During Arc Start: Amperage, Arc Length, Rod Condition, Polarity, Ground, and Hot Start Checks
Stick electrode sticking during arc start usually means the arc is not getting hot and stable fast enough to keep the rod from fusing to the work. The common causes are low…

Stick Welding Arc Blow Causes and Fixes: Magnetic Arc Deflection, Ground Clamp Placement, AC/DC Settings, and Weld Sequence
Stick welding arc blow happens when the arc is pulled, pushed, or deflected away from the joint instead of staying under the electrode. The usual symptoms are a wandering arc, undercut on…

7018 Rod Moisture Contamination Troubleshooting: Porosity, Rod Sticking, Arc Instability, and Hydrogen Cracking Risk
7018 rod moisture contamination is a low-hydrogen failure, not just a storage inconvenience. Damp E7018 electrodes can cause porosity, rough arc starts, excessive spatter, slag trouble, underbead cracking risk, and welds that…
