The joining of materials, typically metals, through the application of heat to create a molten pool is a fundamental process in fabrication. This involves melting the base materials, often with the addition of a filler metal, to form a continuous bond upon cooling. An example is the creation of a strong seam between two steel plates, accomplished by heating the edges until they liquefy and fuse together.
This method offers the advantage of producing joints with mechanical properties comparable to or exceeding those of the base materials. Its implementation has been essential across numerous industries, from shipbuilding and aerospace to construction and automotive manufacturing. Historically, the development and refinement of such techniques have allowed for the creation of complex and durable structures.
