Procedure for use

The Motoman HP 20L cell is designed to streamline the welding cycle efficiently. The operator positions the workpiece on the RM 250 positioner, which rotates the component, allowing the robot to weld in hard-to-reach places. Thanks to the Fronius CMT TPS 5000, welding is smooth, significantly reducing spatter and distortion.

Accessories and customizations

The system is compatible with various water-cooled welding torches and can be combined with automatic torch cleaning systems to maintain efficiency. Sensors and monitoring software are also available to monitor weld quality in real time.

Mathematical formulas for optimal use

To optimize the use of the Motoman HP 20L, it is essential to calculate the welding speed and angle parameters. The basic formula for welding speed is:

$V$

Where:

• V is the welding speed (in mm/s),
• d is the distance to be welded (in mm),
• t is the time (in seconds).

These variables, together with the characteristics of the material and the Fronius generator, determine the quality and strength of the welds.

Sectors of use

This robotic system is used in the automotive , aerospace , and naval , where precision and repeatability of welding are essential. It is particularly suitable for welding complex structures, frames, and tanks.

Maintenance and evaluation of used vehicles

Maintenance of this system requires regular checks of the mechanical components, lubrication and cleaning of the torches, as well as periodic software updates. When evaluating a used model like the Motoman HP 20L, it's important to check the number of operating hours, the condition of the NX100 controller, and whether any major component overhauls or replacements have been made.

Purchasing a used robotic welding cell, such as the Motoman HP 20L with a Fronius CMT power source, offers significant cost advantages while maintaining high operational performance. Furthermore, the availability of comprehensive technical assistance ensures ongoing support to maximize the system's efficiency and longevity
