Optimize weld seam with calculation and profile measurement

13.10.2020 | Inrotech A/S from Denmark achieves the optimal weld seam in a fully automated process with its special welding robot Inrotech-Crawler. This is done by calculating the welding process in advance. When executing the welding does the Robot on the exact measurements of the powerful laser profile scanners (picture above) from Micro-Epsilon back. The scanners are light, precise and compact.

After calculating the welding process, the Welding robots this automatically. He receives the exact measured values for this from the powerful Scancontrol profile scanners.

A scanner is on the crawler fixed. It records the geometry of the seam to be welded before the welding process. The highly accurate profile measurement for the potential weld seam enables the welding to be automated.

Thanks to an optimal control of the exposure time and the high resolution, the sensor delivers reliable measurement results on almost all measurement objects. The compact sensor has a integrated controller. The various connection options via an SDK (Software Development Kit) enable the calibrated profile data to be transferred directly to the customer's software via the Scancontrol DLL.

The Weldlogic technology von Inrotech then calculates, among other things, the number of welding passes, position of the welds, welding speed and pendulum width. Immediately after the calculation, the crawler automatically carries out the welding process.

Cells for robot-based inert gas welding

yaskawa0819 13.08.2019 | Expanded with two very compact turnkey, robot-based inert gas welding cells Yaskawa the “Arcworld” portfolio. Motoman robots, positioners, controllers and power sources are all combined on one platform to save space and are ready for immediate use. This means that the robot cell can be moved quickly and easily if necessary.

It is also very easy to install and operate. The two new models now offer these advantages in the smallest of spaces: The Arcworld RS Mini requires only 2,3 m² The Arcworld HS Micro only requires 1,4 m2 of installation space. The compact cells therefore offer a flexible, space-saving and cost-effective option for entry into automation or as a supplement to manual welding systems.

A manually operated turntable allows parts to be inserted while the workpieces are being processed in the cell. This reduces downtime and increases part throughput.

Beide Compact cells are supplied complete with platform and housing, robot, welding package and all necessary accessories. Each welding package contains a welding power source, the necessary cables, the wire feed and a welding torch. A Motoman AR900 is used as the robot. It has a high path accuracy and is completely designed in protection class IP67.

Cold Metal Transfer welding process convinces Voestalpine

03.04.2018 | Fronius has the CMT welding process recently brought to the most modern welding power source, TPS/i. With the second generation of the cold arc, robot-assisted welding can be carried out in many applications with previously unattainable quality, simplicity and process reliability. Voestalpine was the first to decide to use CMT technology in series production.

Check welds mobile, fast and secure

06.04.2016 | The ultrasonic testing device “Phasis one” from Vogt Ultrasonics guarantees reliable weld point testing with imaging using phased array technology. With a physical resolution previously unattainable by comparable devices, it provides precise information on the diameter of the weld nugget and the remaining wall thickness in the weld area.

In addition, the examiner receives information about the sound attenuation caused by the structural change as an evaluation criterion for adhesive bonds or zinc bonding. Testing device is suitable for checking resistance welded points on steel and aluminum sheets.

The test time is only a few seconds per point. With Phasis one, around 500 to 800 test points can be checked per shift and device. The 121 ultrasonic elements generate a physical resolution of better than 0.35 mm of the weld nugget diameter. The imaging of the phased array technology guarantees reliable evaluation of the test results. Welding defects such as pores or a weld nugget that is too small are reliably detected. Thanks to five hours of battery operation, a weight of just 3,5 kg and a robust aluminum housing, the device is suitable for mobile use, and not just in the automotive industry.

The management software Phasis Manager supports the user with a surface scan for optimal alignment of the test head on the weld point to be tested. The test plans are clearly laid out and can be created quickly. Individually customizable interfaces handle communication with the customer's database. The Phasis Device test and evaluation software is designed for use in the production process. Intuitive to use, it requires little training.
