Arc Welding Safety Standards Arc Welding Safety Standards address the various aspects of arc welding and the safety considerations that accompany them, such as cutting noise. In addition to arc welding safety standards published by national standards bodies and the American Welding Society (AWS), a 13-part series has been published by the International Electrotechnical Commission (IEC), with each part looking closely at a single component of arc welding, setting forth requirements for both performance and safety, highlighting the ever-present attention to safety necessary in arc welding.
