| | Common Causes | Solutions | | :--- | :--- | :--- | | Porosity / Worm Tracks | Gas contamination (wind, lack of gas), dirty metal, damp flux | Move indoors, check gas flow, clean base metal, store wire properly. | | Slag Inclusions | Trapped slag from previous passes, too low of heat input, poor technique | Clean thoroughly between passes (chipping hammer, wire brush), increase voltage. | | Spatter | Voltage too high, incorrect stick-out, wrong polarity | Reduce voltage, shorten stick-out, check/verify polarity. | | Incomplete Fusion | Low heat input, incorrect travel angle. | Increase WFS/voltage, adjust travel angle. |

Increase voltage settings, slow down to allow the base metal to melt, and center the wire directly on the joint root. Essential Workplace Safety (EHS) Guidelines
To get the cleanest weld with FCAW, maintain a (the distance from the contact tip to the metal). For most wires, this is between 1/2" to 1". This pre-heats the wire and ensures the flux activates correctly. Heavy-duty gloves, welding mask (lens shade 10-14), and

The chemical compounds inside the flux core react to the high temperature. They decompose into shielding gases (like CO2cap C cap O sub 2
Flux-cored arc welding (FCAW) is a versatile, high-productivity welding process that uses a continuously fed tubular electrode filled with flux. It combines the advantages of shielded metal arc welding (SMAW) and gas metal arc welding (GMAW): high deposition rates, improved penetration, and suitability for outdoor and high-production environments. FCAW is widely used in construction, shipbuilding, heavy equipment fabrication, and structural steelwork.
Self-shielded FCAW relies exclusively on the chemical reactions within the flux core to generate protective shielding gas and slag.
