Abstract: If it comes to discussions about the next level of industrialization “Internet of Things” / “Industry 4.0” are frequently used technical terms. The vision they stand for, is clear: The actual ongoing digitalization can provide valuable data but its benefit is restricted and very limited. If this data will be shared to a big community much more experts and scientists could use it and develop new solutions which generates new knowledge and brings a remarkable increase in customer benefits. To enable this, it is necessary to connect almost everything to a cyber world, the internet, to create a big data storage, the cloud, and to increase the data communication. The overall goal of I4.0 are autonomous working smart factories. All necessary manufacturing information is available in the cloud, intelligent software tools manage and control manufacturing processes and organize the supply chain and goods will be produced on demand by additive manufacturing technologies.

This impacts also welding and the welding equipment development: welding knowledge and all kind of welding parameters have to be digitalized, microprocessors will take over the essential part of the hardware and software will play in future the key role. And also new challenges will arise: ultrahigh speed data communication within the welding machine but also within the internet and the development of strategies for securing data. Last but not least virtual welding will get a necessary tool to bring the digital information into a manufacturing equipment and to check the plausibility.

Abstract: One of the pillars of the 4th Industrial Revolution is Additive Manufacturing (AM) technology that it is used currently in a smaller scale, but which has within manufacturing its most significant and lasting commercial impact.

Several hurdles need to be overcome to achieve full utilisation of additive manufacturing in most industrial scenarios, from parts size and resistance to the ability to mix materials in one production run and, last but not the least, the qualification of personnel able to use these technologies. Therefore, to realise the full potential of AM, manufacturing organisations must focus on developing a capable and skilled AM workforce.

EWF is tackling these aspects in collaboration projects focusing on two main topics, research and development (RTD) and training and qualification of personnel.

Through the participation in RTD projects, EWF is aware of the progress the AM technologies are undergoing, disseminates the results in its network and includes the innovations in the EWF personnel qualification profiles. As such, EWF is also  nvolved in collaboration projects addressing the development of new qualifications for additive manufacturing personnel which are tackling the industrial needs in this field.

 

The present paper focuses on the results obtained in some of the projects EWF has been involved.

Abstract: The extremely rapid development of welding after the 70’s and 80’s has imposed first the automation - and then the robotization of manufacturing processes. If at first the applications were focused on simpler and more precise parts, and the robots (non-adaptive at that time) were still able to weld the structures well, but in time the components intended for robotic welding were increasingly complex and imprecise.

It became necessary to equip the robotic systems with adaptive functions, first with the geometric one, then with the process adaptivity. At present, robots with an expanded adaptability are able to process more and more common parts, whose preparation for welding costs obviously less.

 

The paper presents the structure and functioning of the adaptive robotic systems for electric arc welding, especially the sensory devices and their adaptive regulators, as well as the specific developments of the welding equipments necessary for them to be successfully integrated into adaptive robotic cells and systems.
