Basic Details about Welding and Welding Control

摘要

For Japan with its frequent great earthquakes, seismic design is very important. Further, there are cases in which welds can become the starting point of fractures that lead to the collapse of steel structures. In the No. 37 issue (December 2012), basic details about welding and welding control in steel-frame building structures and information regarding the key dynamic performance characteristics of welds were introduced. The current issue introduces a discussion about on-site welding, mainly the problems that occur in on-site welding and appropriate counter-measures.
