Welding
Manufacturing Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A manufacturing process that permanently joins metals or thermoplastics by melting the faying surfaces, usually with added filler, so that a continuous metallurgical bond forms on cooling. It differs from mechanical fastening because the parts fuse into one body.
Example in context
“The fabrication shop chose welding instead of bolting because the pressure vessel had to remain leak tight under cyclic thermal loading.”
“İmalat atölyesi, basınçlı kabın çevrimsel ısıl yükleme altında sızdırmaz kalması gerektiği için cıvatalama yerine kaynağı seçti.”
Where engineers use it
Welding appears in structural steelwork, pipelines, shipbuilding, and automotive assembly. Engineers specify welding procedures, consumables, and inspection levels because joint strength, distortion, and residual stress determine whether a fabricated structure meets code and survives service loads.
Synonyms: fusion joining
Practice: can you use “Welding” at work?
During a workshop assessment, a trainee must explain why welding was selected for a steel bridge girder splice and identify which joint preparation and inspection steps the welding procedure requires.
Show a model answer
“Welding fuses the two plates into a single load carrying member.”
