Hitsausvirtaan

Hitsausvirtaan refers to the electrical current used in welding processes. The amperage of this current is a critical parameter that directly influences the heat input into the workpiece and the filler material. Selecting the correct welding current is essential for achieving a strong and sound weld.

Too low a welding current can result in insufficient penetration, leading to a weak joint with a shallow fusion zone. It may also cause arc instability and spatter. Conversely, excessive welding current can lead to excessive heat input. This can cause burn-through, especially on thin materials, distortion of the workpiece, and an overly wide heat-affected zone, potentially degrading the material properties.

The optimal welding current depends on several factors including the type of welding process (e.g., stick welding, MIG welding, TIG welding), the type and thickness of the base metal, the welding position, and the type and diameter of the welding electrode or wire. Welders often use charts or experience to determine the appropriate current setting for a given application. Proper adjustment of the welding current is fundamental to controlling the weld pool, ensuring proper fusion, and producing a weld that meets the required mechanical properties and quality standards.
