The OTC FD19-BT6 - The Most Versatile 7-Axis Welding Robot on the Market
The FD19-BT6 solves a problem that classic 6-axis robots fail at: collision-free welding on complex, hard-to-reach components. With its seventh axis and integrated welding cable, it is particularly designed for the automotive industry, where body and chassis parts require tight fixtures and nested geometries.
Collision-Free Welding
Evasive movements without interrupting the welding path, even in tight fixtures.
Integrated Welding Cable
No external cable management needed, less interference contour in the working area.
Designed for Complex Components
Ideal for nested geometries, as typically found in the automotive industry.
What Sets the FD19-BT6 Apart
The most important features at a glance:
Integrated Welding Cable
Reduces collision risk during programming.
Stable Robot Posture
Torch position stays unchanged during welding.
Simplified Manual Operation
Thanks to synchronized motion technology.
7-Axis Robot Avoids Interference
Finds the most effective torch posture, even with complex fixtures.
Circumferential Welding with One Robot
The seventh axis moves around the workpiece, no second robot needed.
Designed for Series Production
Repeatability of plus/minus 0.05 mm even on complex paths, crucial for body and chassis parts with tight tolerances.

Practical Examples
In the automotive industry, tight build tolerances, nested assemblies, and high cycle times all come together. Classic 6-axis robots reach their limits here as soon as the torch needs to navigate around an obstacle without interrupting the seam. The seventh axis of the FD19-BT6 creates exactly this additional degree of freedom, making it the preferred choice for frame, chassis, and body parts where standard robots fail due to accessibility limits.
Example: Chassis Arm:
A chassis arm with several nested weld-on parts often requires multiple repositioning steps or a second robot for hard-to-reach seams. The FD19-BT6 welds these components in a single pass, without needing to change fixtures.
Frequently Asked Questions
It allows avoiding interference with fixtures and workpieces and finding the most effective torch posture, and also enables circumferential welding with just one robot.
6 kg at the end effector, plus an additional 10 kg additional load on axis 3.
No, according to the datasheet only floor mounting (F) is intended.
Yes, particularly well suited. Body and chassis parts often have nested geometries where classic 6-axis robots have to collide or interrupt seams. The seventh axis of the FD19-BT6 solves exactly this problem and makes it the preferred choice in automotive series production lines.
