The ever-increasing world population has influenced human needs for activities, one of which is safe means of transportation. To meet demand, industries operating in the automotive sector are also developing to improve the comfort and safety of their products. This research aims to evaluate one of the transportation products based on the AWS D1 standard. 1 2015, namely about welding defects using GMAW welding that occur during the manufacturing process. This research uses a visual inspection method by directly observing the manufacturing process and evaluating welding results based on the AWS D1 standard. 1 2015. The results of observations show that there are 6 welding defects that occur in dump truck body manufacturing, namely: Undercut, Spatter, Porosity, Pin Hole, Surface Cold Lap, Capping. Where three of the six welding defects above meet the requirements and are included in the acceptance criteria qualifications according to AWS D1.1 2015. Where the capping, undercut and pinhole welding defects are included in the defects that must be rejected or not accepted and cannot be repaired anymore.
