A hitsausliitos, or welded joint, is a permanent connection formed by the localized melting of materials (usually metals) to create a strong bond. This melting is typically achieved by applying heat and sometimes pressure, with the addition of a filler material that solidifies to become an integral part of the joint.

The process of creating a hitsausliitos involves several key stages. Preparation of the surfaces to be joined is crucial, often requiring cleaning to remove rust, oil, or other contaminants that could weaken the weld. Then, the heat source, such as an electric arc, gas flame, or laser, is applied to melt the base metals and any filler material. As the molten material cools and solidifies, it forms a metallurgical bond that is often as strong as, or stronger than, the base materials themselves.

There are numerous types of hitsausliitokset, classified by the geometry of the joint and the welding process used. Common joint types include butt joints, lap joints, corner joints, T-joints, and edge joints. The choice of welding process depends on the materials, thickness, required strength, and desired appearance. Popular welding methods include shielded metal arc welding (SMAW), gas metal arc welding (GMAW or MIG/MAG), gas tungsten arc welding (GTAW or TIG), and submerged arc welding (SAW).

Hitsausliitokset are widely used in various industries, including construction, automotive manufacturing, shipbuilding, aerospace, and pipeline fabrication, due to their strength, durability, and cost-effectiveness. However, proper execution and inspection are vital to ensure the integrity and safety of the final connection.
