käsihitsausmenetelmä

Käsihitsausmenetelmä refers to manual welding processes where the welder controls the welding torch or electrode by hand. This category encompasses a variety of techniques used to join metals. The most common manual methods include shielded metal arc welding (SMAW), also known as stick welding, where a consumable electrode coated in flux is used; gas metal arc welding (GMAW), or MIG welding, which uses a continuously fed wire electrode and a shielding gas; and gas tungsten arc welding (GTAW), or TIG welding, which employs a non-consumable tungsten electrode and a separate filler material if needed, all while being shielded by gas.

The selection of a specific käsihitsausmenetelmä depends on factors such as the type of metal being joined, its thickness, the required weld quality, the position of the weld, and the available equipment. Manual welding offers flexibility and is suitable for a wide range of applications, from heavy fabrication and construction to intricate repairs and artistic metalwork. However, it requires significant skill and precision from the welder to achieve consistent and high-quality results. The welder's ability to maintain consistent arc length, travel speed, and electrode angle is crucial for controlling the weld pool and ensuring proper fusion.
