Trumpf enters the world of automated arc welding

Cobot handles welding process and programming along with welding takes just minutes

Trumpf enters the world of automated arc weldingLuton-based Trumpf Ltd has unveiled the TruArc Weld 1000, its first automated arc welding system which comes equipped with a collaborative robot (cobot). After the operator has manually guided the cobot over a component, it then automatically carries out the weld, which is significantly more efficient than would be possible manually.

With this new system, Trumpf says it is responding to the increasing lack of skilled workers and the system gives fabricators the opportunity to enter the realms of automated welding. CE-compliant and approved by TÜV Austria, customers can rest assured that the TruArc Weld 1000 meets the very highest safety standards.

Unlike conventional industrial robots, operators can interact with the cobot, guiding it over the part by hand. A built-in sensor ensures it responds smoothly. Trumpf has equipped the cobot with an operating unit which lets users store the weld path’s start and end points as well as intermediate waypoints in order to create the program.

Welding made easy

Furthermore, the cobot control system includes templates for welding programs and parameters that cover scenarios such as different sheet thicknesses. Combined with the operating unit on the welding torch, this greatly simplifies the task of programming the cobot and weld with the TruArc Weld 1000 can be carried out within minutes. Next to no previous experience is needed handling the system.

The welding system offers an automated alternative for many parts that users would normally weld by hand and thanks to the rapid programming function, fabricators have an affordable means of tackling short production runs and one-off pieces, even if the parts only require a short weld seam.

The TruArc Weld 1000 produces straight and even seams every time, prevents spatter and offers very high machining quality.

Simultaneous set-up and welding

Inside the TruArc Weld 1000 is a partition that can be raised and lowered, allowing users to divide up the working area and choose between welding one large part (single-station operation) or several smaller ones (two-station operation).

CobotIn single-station operation, the robot can weld parts measuring up to 2,000 x 600 x 600mm. Other ratios of width to length are also possible depending on part dimensions. In two-station operation, the TruArc Weld 1000 can process smaller parts measuring up to 600 x 600 x 600mm.

To ensure it can easily reach both stations, the robot travels between two positions along a linear axis. While it is busy welding on one side, the operator can use the time to set up a part on the other side. The robot program can be transferred automatically from one station to the other.

Customers can carry out commissioning of the TruArc Weld 1000 themselves within a few hours using the dedicated video tutorials. From the wire coil to the welding parameters, the system comes with everything needed to get started with the welding process.

No classroom training is required for machine operators as the video tutorials contain all the information required to quickly learn how to operate and program the easy-to-use machine.
