Panasonic TAWERS Robots

The Arc Welding Robot Solution (TAWERS)

This advanced robot controller with integrated welding power source and range of rigid high speed arms from Panasonic, fuses control of the robot motion, welder waveform and servo wire feeder to adjust and correct for dynamic changes in the welding process.

TAWERS is the first robot with Embedded Arc Control (EAC) technology, soaring beyond conventional digital communication systems, delivering the first generation of fully software-controlled robotic welding solutions with Synchronization between welding waveform and robot motion

A combination of constant voltage and pulse welding technologies in the SP-MAG welding process leads to significantly reduced spatter levels, low heat input, low susceptibility to arc blow, wide process windows and excellent thin material and gap handling capabilities.

What this means for YOU

High Quality Welds | Faster cycle times | Cleaner Welds | Reduced levels of spatter | Less distortion

Features

Lift-start / Lift-end

At the start and end of the welding process, the robot quickly lifts the welding torch. By coordinating the robot movement with the specified welding parameters and the wire feed control, quality and cycle time are improved.

Flying Start

Gives the start/end command a short time before the beginning/end.

Automatic Wire Retract Function

When the robot moves to the next welding start point, the welding wire is automatically retracted, thereby improving the re-ignition.

Repeat Function For Arc Ignition

If an error is detected when the arc is ignited, the robot automatically starts a new ignition attempt.

Programming Aids

Incremental Movement

This function allows the robot to move a set distance by clicking on the jog dial. This function is useful when working in narrow and limited spaces, or when fine tuning the robot position.

Torch Angle Display (Control Panel)

The torch angle display on the robot control panel reduces the component programming time and leads to an improved weld seam appearance.

Simple Calculation of Welding Parameters

Input of plate thickness T1 and T2 as well as seam type.

Finished! You immediately receive the recommended parameters.

Weld Navigation Enables Parameter Determination

A large parameter database based on our experience is available for your selection. The weld navigation system guides you quickly and safely to a perfect weld.

Welding Processes

SP-Mag

Super Imposition Control SP Mag Process

Drastic reduction of the weld spatter, highest seam quality with low heat input

Super AWP

Active Wire Welding Process

Achieve a much higher welding speed of up to 2m/min with greatly reduced spatter

Tig

HF or Lift Arc TIG Welding Process

Up to 3 times higher welding speed than conventional Tig Filler welding

HD Pulse

Hyper Dip Pulse Welding Process

Pulse welding process with better penetration and better quality at higher welding speeds, low notch and undercut effect

Additional Software / Hardware

Tawers Spiral Weave Function

Welding in helical movements together with synchronised welding parameteres and wire feed speed produces an ideal welding result for aluminium MIG welding. Included in this option are the TAWERS aluminium MIG function and the TAWERS synchronous weave low-pulse function. These spiral weave functions are used for perfect aluminium welding of varying plate thicknesses, e.g. 2mm plate to 6mm plate.

Cooperative Multi-robot Control Master/Slave Function

Enables communication between multiple robots. Harmonic movement: Panasonic offers software solutions that allow for harmonious movement between the external axis and robot or multiple robots. The software ensures that the relative speeds and the relative speed of the path are sychronised with each other.

Automatic Distance Control Auto Extension

^{(available for MIG/MAG & TIG)}

Simplified programming for uneven-shaped workpieces and adaptive control for heat distortion compensation. The robot detects changes in the distance between the contact tip/tungsten electrode and the workpiece and automatically compensates for this.

Contact Sensor System

The contact sensor can detect deviations between the programmed and actual welding start point and correct these automatically. This feature is also available as a non-contact option using laser technology.

Arc Sensor System

During weave or pendulum weave welding, the arc sensor can measure the changes in the welding current, which occur during welding, and automatically correct to maintian correct welding parameters.

Welding Data Management

The welding date management software includes 3 main functions:

Welding data monitoring

^(extended)
Monitoring the compliance within set limit values and outputting signals when the limit value is exceeded. In contrast to the standard system, up to 50 different 'welding parameters' can be set with two different signal outputs (error / alarm).

WDM extended

Welding data recording

Recording the welding parameters in milli- or microseconds of a weld. The recorded data can be exported and checked by means of suitable software [e.g. EXCEL). Then the current / voltage history settings are visible.

WD R

Welding data storage

^{(log function)}
Recording the set and actual welding parameters as average values for each welding section (weld seam) in synchronisation with the welding program.
