About this book

This Guide is based on several decades of author’s research and practical experience in the areas of process optimization, ventilation and energy conservation in welding shops of auto manufacturing and maintenance facilities. The Guide will describe principles of Weld Fume Control, advanced ventilation systems for facilities with welding and allied processes and with energy conservation opportunities that result from the process related measures to reduce emission of fumes and gases and the building envelope improvements. The objectives of the Guide are to improve the health and safety in the industrial environment and offer strategies for energy conservation. The Guide is designed for engineers, production operators and energy managers.

Chapter 1. Introduction
Abstract
Welding operations are often used in different types of manufacturing facilities (mechanical, automotive, airspace, shipbuilding, maintenance, etc.). When welding, workers are exposed to fumes and gases generated by the process. The potential exposure varies with the process and welding conditions employed. Hand welding and semiautomatic, automatic, spot, joint contact, robot, and gas welding are the most common welding processes in manufacturing and repair industries. Contaminant control and comfort conditions in welding shops can be achieved using a combination of process optimization and enclosure as well as properly designed ventilation systems.

Chapter 2. Design Methodology
Abstract
The following methodology describes a process of the HVAC system selection and design. It reflects all important stages of design, and allows all parties involved in the design process (e.g., architects, process and mechanical engineers, building owners, etc.) to better understand the information required for HVAC system design and the order of tasks to be performed. Figure 2.1 shows a design methodology decision tree.

Chapter 3. Design Criteria
Abstract
As the design conditions for outdoor air temperature, humidity and wind, use the following information, which can be obtained from the National Climate Centers, WHO World Data Center or, for the United States of America, Canadian and many international locations from (ASHRAE 2017a):

Chapter 4. Processes and Contaminant Generation in Welding Shops
Abstract
Industrial facilities discussed in this Guide include those which house operations relying on welding, cutting, brazing, and joining processes, e.g., automotive plants, shipbuilding and repair wharfs, maintenance, and repair shops.

Chapter 5. Target Levels
Abstract
Contaminants, which can be produced in welding and allied processes, are as follows. The metallic components are typically found in the form of oxides and/or fluorides.

Chapter 6. Ventilation
Abstract
Clean air for welding operations is provided by ventilation systems, which typically consist of process and local exhaust systems and general ventilation supply and exhaust systems. The most efficient method of contaminant control in the occupied zone of the welding shop are [VGAI 2000]:

Chapter 7. Energy Conservation
Abstract
Energy conservation opportunities in industrial facilities in general and specifically in welding shops include process improvement measures, measures related to the building envelop, local and general ventilation systems. This section summarizes experiences gained through hands-on energy audits conducted at different international sites; best practices published in literature and obtained from the industry, as well as modeling and simulation conducted under the IEA EBC program Annex 46 (Annex 46 2014) and Annex 61 (Zhivov and Lohse 2020).
