GMAW를 이용한 V형 맞대기용접에서 와이어전극돌출길이 변화에 따른 용접 특성 연구
Study on Characteristics of V-type Butt Welding Using GMAW Depending on Variations in the Protrusion Length of Wire Electrode
The purpose of this study is to determine more variables in welding characteristics of ATOS(steel for automobile structure) 80 high tensile steel available in market, and in terms of welding using GMAW(gas metal arc welding), this study seeks to examine how welding characteristics of ATOS 80 may vary depending on protrusion length of wire electrode. The major characteristics of this study can be summed up as follows, this study analyzed welding characteristics of ATOS 80 by changing the protrusion length of wire electrode (10㎜, 15㎜ and 20㎜) in welding section, and also used visual inspection and radiograph test to examine observations of major defects on welding section.
