täytejohtoa
Täytejohtoa, a Finnish term, translates to "filler wire" or "filler rod" in English. It refers to a material used in various manufacturing and repair processes, primarily in welding and brazing, to join two or more separate pieces of metal or to fill gaps and build up worn surfaces. The composition of täytejohtoa is typically similar to the base metal being joined, although alloys can be used to enhance specific properties like strength or corrosion resistance. Its purpose is to melt and fuse with the parent materials, creating a strong and continuous bond upon cooling. Different types of täytejohtoa are available, each suited for specific metals and welding or brazing techniques. The selection of the correct täytejohtoa is crucial for achieving a successful and durable joint. Beyond welding and brazing, the concept of täytejohtoa can also extend to other joining or filling applications where a malleable material is used to bridge gaps or provide structural support.
