Comparison of Cobot and Manual Welding Based on Arc Parameters
A newsletter from Belgian Welding Institute (BWI)
The present publication proposes an empirical evaluation of real-time quality monitoring of MIG/MAG welding of dissimilar high strength steels DP800 and DP1000 in T-joints based on the measurement of the processes parameters. A new strategy is proposed to evaluate the quality of the welds of HSS materials using the ISO 5817 standard. From the obtained results, a correlation between the process parameters and the quality of the weld was established. An operational comparison between cobot and manual welding was performed based on their repeatability. The results confirm the higher repeatability of the mechanised cobot process and the feasibility of using process parameters as an in-situ NDT technique for production control. [LINK]
New Strategy to Evaluate Specific and Complex Welds Application Using EN ISO 5817 Standard
A newsletter from Belgian Welding Institute (BWI)
In order to evaluate welding of specific and complex applications, such as welding of high strength steel for manufacturing of electric vehicles structures, it’s necessary to adapt the standard to its assurance and secure the quality of the process. With this idea in mind, a new strategy was proposed to evaluate the welds based on the ISO 5817 standard based on safety and stress categories. The safety category defines the consequences of failure of the single welded joint with respect to the effects on persons, facilities, and the environment. [LINK]
Manual, Cobot and Robot Welding? How to Make the Choice
A newsletter from Belgian Welding Institute (BWI)
There are several reasons why automation of welding production is gaining more and more importance. For example, skilled welders are nowadays scarce. Besides that, the weld quality obtained when using automatic welding processes has shown to significantly reduce the need for rework. [LINK]
High Strength Steels: An Overview
A newsletter from Belgian Welding Institute (BWI)
The ongoing need to reduce the weight of products while increasing strength has resulted in new generation steel manufacturing using special heat treatments to procedure high strength steels. The special steels can be divided in three major groups (Figure 1): High-Strength Steels (HSS) with a yield strength of 210 to 550 MPa, including among others, the CMn Steel, the steel bake hardening (BH) and the high strength low alloy steel (HSLA); the Ultra-High Strength Steels (UHSS) with a yield strength greater than 550 MPa; and the Advanced High Strength Steels (AHSS), also called of Multiphased High-Strength Steels, with a yield strength greater than 700 MPa, what includes, among others, the Transformation Induced Plasticity (TRIP), the Dual Phase (DP), the Complex Phase (CP) and the Martensitic Steels.

Mobility and electric vehicle: development of a safe urban electric vehicle, from idea to manufacture
A newsletter from CIDAUT
Mobility has undergone constant evolution throughout history. However, in recent years, it is undergoing an even more drastic change. The greater concentration of the population in cities, together with the growing increase in the number of vehicles worldwide, are making the air quality in urban centers increasingly worse, and therefore, that the consequences of this pollution affect a greater number of people. Therefore, due to the need to act against this problem, the Cidaut Foundation determined that the urban environment should be the source of the electrification of mobility. [LINK]
First safe urban electric vehicles prototypes ready to be tested in Avangard Project
A newsletter from CIDAUT
The aim of Avangard is to design a microfactory for the production of electric cars and bikes applying Industry 4.0 solutions and minimizing the footprint of both the production and use phase of the vehicles. After the first third of this three years project, the first prototypes of electric cars have been produced and the bicycles will come soon. Taking advantage of the modularity of the vehicle design, the prototypes correspond to different configurations: two standard four seat vehicles and two vans have been manufactured, in the case of the four seats vehicles one of them corresponds to the short length one, while the other is track extended. In the case of the vans the difference among them is the installation of photovoltaic panels in the external surface of one of them, which allows 20 additional kilometres range thanks to the solar irradiation.

Blockchain applied to the manufacturing of light urban electric vehicles
A newsletter from CIDAUT
Cidaut is involved in Avangard project whose main objective is to develop advanced manufacturing solutions tightly aligned with business needs and oriented to the assembly of electric urban vehicles: 4 passengers’ cars, vans and bicycles. To achieve this ambitious target some innovative solutions are been applied both in the physical and digital ambit. From the physical point of view robotized integration of laser cutting-shaping –welding for 3D components, supersonic deposition of metallic powders for high speed 3D printing and large volume and high-speed 3D polymeric printing are the most relevant solutions.
