Hitsauspökistä

Hitsauspökistä, a Finnish term, generally refers to a small, hardened lump or blob of molten metal that can form during welding processes. These pökistä can arise from various factors, including the welding technique, the type of welding consumable used, and the base materials being joined. The formation of hitsauspökistä is often considered a defect or an undesirable side effect in welding.

These metal blobs can vary in size and composition. They might be small spatter particles that have adhered to the workpiece, or larger, more integrated formations that have detached from the weld pool. Their presence can be attributed to issues like poor gas shielding, excessive welding current, or incorrect electrode angle. In some cases, they can also result from the melting and re-solidification of filler material or base metal.

The consequences of hitsauspökistä can range from purely cosmetic to more significant structural concerns. They can affect the surface finish of the weld, potentially requiring additional cleanup or grinding. More critically, if they become embedded in the weld metal, they can act as stress concentrators, weakening the joint and potentially leading to premature failure under load. Therefore, controlling and minimizing the formation of hitsauspökistä is an important aspect of achieving high-quality welds. Welders often employ specific techniques and adjustments to prevent their occurrence.
