Electrode Angle
Electrode inclination is the process where the workpiece is driven off by the electrode. An excessively large angle can lead to uneven penetration depth and lack of fusion.
Physical-Chemical Mechanism of Action
Electrode inclination is the process where the workpiece is driven off by the electrode. This happens through mechanical force and chemical reactions between the electrolyte and the metal. An excessively large angle to the workpiece surface can cause certain areas of the workpiece to be driven off slower or faster than others.
Metallurgical Relevance & Risks in Welding
An excessively large electrode inclination angle can lead to uneven penetration depth and lack of fusion. This can result in missing weld spots, cracks, or poorer mechanical properties of the weld. Additionally, excessive electrode inclination can cause overheating of the workpiece, leading to distortion or failure.
Shop Practice & Instructions
Set the electrode inclination angle so that even penetration depth and a clean weld profile are ensured. Typically, this means an angle between 30° and 45° to the workpiece surface. For special materials or welding processes, this angle may vary, so it's important to follow the manufacturer's instructions. Continuously monitor the feed and adjust the electrode inclination angle accordingly.
