A data framework for environmental assessment of metal arc welding processes and welded structures during the design phase

Life Cycle Assessment of Fusion Welding Processes—A Case Study of Resistance Spot Welding Versus Laser Beam Welding

“…The integration of life cycle assessment within the weld planning and production chain utilizing a data platform is shown by Favi. [ 25 ]…”

“…The integration of life cycle assessment within the weld planning and production chain utilizing a data platform is shown by Favi. [25] Summarizing the literature survey, it can be concluded that life cycle assessment has become a standard tool in manufacturing technology from a plant design perspective [26] comprising the analyses of other production processes such as cutting and turning [27] or even certifying entire production-oriented companies. [28] The evaluation of the environmental impact of welding processes is obtained on basis of the individual amount of consumed electrical energy and resources, which requires corresponding data acquisition and handling during the processes.…”

A Rule-Based System to Promote Design for Manufacturing and Assembly in the Development of Welded Structure: Method and Tool Proposition

“…Welding is a joining process widely used in various industries, such as automotive, aeronautic, shipbuilding, oil and gas, and industrial/chemical plants. Design for welding (DFW) requires the definition of a list of design actions that are related to the geometry of the product under development and affect aspects of the overall product design such as (i) the type of welding, (ii) the material to weld, (iii) the geometry and the thickness of the weld plates, (iv) the geometry of the bevel, (v) the location of the weld beam, (vi) the dimensions for weld beam, (vii) the possibility to use intermittent versus continuous weld, and (viii) the accessibility for the weld gun and fixture equipment [9]. Moreover, many other activities are related to the welding process itself such as the settings of welding parameters (current and voltage), the consistency of joint design with approved standards, the levels of distortion in the base material, the selection of the wire/rod material and diameter, the number of passes, and the welding speed [10].…”
