langansyöttönopeus

Langan syöttönopeus, often translated as wire feed speed, is a crucial parameter in welding processes, particularly in gas metal arc welding (GMAW) and flux-cored arc welding (FCAW). It refers to the rate at which the welding wire electrode is fed from the spool to the welding gun and into the weld pool. This speed is directly controlled by the welding machine's wire feeder mechanism.

The langan syöttönopeus significantly influences the welding arc characteristics and the resulting weld bead. A higher wire feed speed generally leads to a higher deposition rate, meaning more molten metal is added to the joint in a given time. This can result in a wider and flatter weld bead. Conversely, a lower wire feed speed results in a lower deposition rate, typically producing a narrower and more convex weld bead.

Optimizing the langan syöttönopeus is essential for achieving sound welds with desirable mechanical properties. If the wire feed speed is too high for the given voltage and travel speed, it can lead to an unstable arc, excessive spatter, and a lack of fusion. If it's too low, the weld may be too narrow, have insufficient penetration, and be prone to porosity. The correct langan syöttönopeus is typically set in conjunction with voltage and travel speed to maintain a stable arc and achieve the desired weld profile and penetration. Different welding applications, material types, and joint configurations will require specific adjustments to the langan syöttönopeus.
