Global Market Analysis for Welding Power Source and Welding Robot (I)

Abstract

The authors have been introducing the trends of the Korean welding and joining industry 1-4) and the global welding material industry 5,6) through the Journal of Welding and Joining. This article will introduce and summarize the status of the welding power source and robot market. According to the Welding and Joining Handbook from Korean Welding and Joining Society, welding automation systems utilizing robots consist of robot arms, controllers, welding power sources, transport devices for welded specimens, robot movement devices, sensors, safety devices, and fixing devices for welded specimens 7) . Their most important components are the welding robots (robot arms and controllers) and welding power source, which are commercialized by specialized companies and applied in the industry. This article introduces the market status of the welding robot and welding power source using data from 2007 to 2017 in "Welding Market Annual Research & Trend" (MART) published by Shinbo 8) . This article classifies welding robots and welding power sources into arc welding and resistance welding, and summarizes the global market status and market status of major consuming countries.
