Basic Details about Welding and Welding Control

摘要

For Japan with its frequent great earthquakes, seismic design is very important. In a great earthquake, while it is assumed that collapse will occur in wooden and concrete structures, it is commonly understood that seismic design has provided steel structures with sufficient seismic resistance. However, there are cases in which inappropriately applied welds can become the starting points of fractures that lead to steel structure collapse.
