Purpose: This paper represents the current status of welding industry of South Korea - how much the welding industry accounts for in monetary terms in the manufacturing industry of South Korea. Design/methodology/approach: We classify welding industry into welding equipment industry and materials & the welding engineering sub-industry. To decide the portion of the welding industry in other engineering industry, we adopt the Welding-Related Expenditures, Investments, and Productivity Measurement in U.S. Manufacturing, Construction, and Mining Industries, a report published by AWS in 2002. The statistical analysis was performed based on the NSO and KITA data. Findings: In South Korea, the welding-related portion in the engineering industry showed much higher figures - about 9 times higher in production amount and over 5 times in export amount - than the welding equipment and materials industry. In addition, the total production of the welding industry amounted to 2.6 billion $, indicating that the welding industry holds a very important place in the entire domestic industries. Research limitations/implications: The welding industry of South Korea was statistically analyzed using the welding related expenditure of the manufacturing industries. Research limitations/implications: This research quantitatively showed the relative importance of the welding industry in South Korea. Originality/value: Due to the nature of welding industry, it is difficult to identify the boundary of welding industry. In addition, monetary impact of welding industry was not revealed in practical manner. In this paper, we categorize the welding industry into two sub-industries and analyze the statistical data with our framework to reveal monetary impact of welding industry. With our results, it is possible to estimate the economical effects of welding industry in South Korea.
