The Challenge to get Higher Quality Arc Welding for the Automotive Body Assembly Production

In recent years, arc welding as an automotive body welding method has come to form two to five percent of all the joining points. This is because arc welding is suitable for the closed section structure-advantageous for lightweight-of a car body. On the other hand, its weakness is deterioration of thin sheets (1.2mm or less thick) quality used in the body. Each automaker is working hard on technology to deal with this problem. This time, on the occasion that DAIHATSU MOTOR adopted arc welding of thin sheets of a car body for the first time, we tackled a question of how we can achieve the top quality. Here, we would say that the new arc welder we have developed for thin sheets is the answer to this question.
