A Study on GMA Welding Automation of STS301L Joint using Design of Experiment
SeungYeb Baek, IlSeon Sohn
Abstract
  Stainless steel sheets are widely used as the structural material for the railroad cars and the commercial vehicles. These kinds structures used stainless steel sheets are commonly fabricated by using the GMAW (gas metal arc welding). For fatigue design of GMA welded joints such as fillet and plug, ring type joint, it is important to obtain optimum design factor information on GMA welded joints. in this paper, analysis approach for fatigue test using design of experiment are evaluated optimum factor in GMA welded joint type and geometrical parameters of materials. Using these results, that factors applied to fundamental information for fatigue design.
Key Words: Design of experiment, Fatigue strength, Gas metal arc welding, Main effect, Interaction analysis
