Choosing the appropriate tungsten electrode diameter is mainly based on the material thickness of the welding workpiece, the amount of current, and the specific requirements of the welding process.
Firstly, the welding current is a critical factor in determining the electrode diameter. Smaller diameter electrodes, such as 1.0mm or 1.6mm, are suitable for low-current welding and are often used for thin plates or fine welding, allowing for better control of heat input and avoiding burn-through and deformation. Conversely, larger diameter electrodes (such as 3.2mm or 4.0mm) are suitable for high-current welding and are used in thicker materials or welding situations requiring deep penetration, capable of withstanding stronger heat loads and ensuring arc stability.
Secondly, the thickness of the welded workpiece will also affect the choice of electrode diameter. thin plate welding usually uses thin diameter electrodes to ensure that the weld seam is fine and the heat-affected zone is small; Thick plate welding favors coarser electrodes to provide a more concentrated heat source and stable arc.
In addition, the electrode diameter will also be required by the welding position, equipment type and welding method (manual or automated). In conclusion, reasonable electrode diameter selection can help improve weld quality, extend electrode life, and improve welding efficiency.
