This research fulfills a need for an updated assessment of engineering control technology used by the welding industry, to reduce worker exposures to toxic substances found in welding fumes and gases. The objectives of this investigation were to (1) identify and summarize research studies in the literature which provide information on the control of worker exposures to arc welding fumes and gases, and (2) provide recent data collected by the author on the effectiveness of existing control measures in the field. Prior to collecting data, the author conducted walk-through surveys at numerous welding shops to gain a basic understanding of various arc welding operations, hazards associated with these operations, and control measures that are currently in use by industry. Then, nine in-depth case studies were conducted of actual arc welding operations to identify worker exposures to toxic welding fumes and evaluate the effectiveness of existing engineering control measures in reducing welding fume exposures. This was accomplished by collecting industrial hygiene air samples, assessing control measure performance, and documenting work practices. Four of the case studies, representing four types of engineering controls for welding operations, are presented in detail in this paper. Pertinent data and observations collected during the other five case studies are also discussed. From the information presented, readers will gain an understanding of the actual effectiveness of certain engineering control methods in the field and whether the data does or does not support the findings of other welding fume control research (primarily laboratory-based). In addition, the data will show how typical welding fume exposures compare to current occupational exposure limits and will demonstrate the range of welding fume exposure levels for several of the more common base metals (carbon steel, stainless steel, aluminum) and four of the most common arc welding techniques (shielded metal, gas metal, flux cored, and gas tungsten). This paper is also a useful technical reference for occupational safety and health engineers and industrial hygienists who are unfamiliar with arc welding processes, their hazards and available control methods.

Advances in science and technology have transformed the welding industry in recent years, with new developments in arc welding at the forefront. Arc welding control details Professor Pan Jiluan's remarkable achievements in this area using innovative methods which have given outstanding results and which have not been described in any previous publication. Arc welding control covers all aspects of the technology. Part one quantitatively describes the dynamic behaviour of arc welding, the power sources used and their effect on welding technology through the basis of control theory. Part two then describes new ways of controlling the welding arc through modern electronics. Part three establishes the first mathematical model of the arc sensor on the basis of control theory and part four describes a new method for measuring weldment temperature fields using the colorimetric-imaging method. Part five describes the idea of recognizing weld grooves with a three-dimensional vision system and automatic programming of the weld path. This comprehensive and authoritative treatment of the arc welding process and its control will make Arc welding control the essential resource for all welding engineers looking to use the technique to its maximum effectiveness. A major new handbook covering all aspects of arc welding Describes many novel and previously un-published techniques in detail Covers arc welding behaviour, arc control methods, arc sensors and seam tracking, temperature measurement and robotics
