High-performance TIG welding for precise, productive joints
InFocus combines the weld quality of TIG welding with a concentrated, stable arc. This enables higher welding speeds and narrow, deep welds – for automated welding tasks on sheets, tubes and complex components.
OSCAR PLT helps you adapt the torch technology and process configuration to your welding task and existing motion system.
Your benefits at a glance
| • | Higher productivity compared with conventional TIG welding |
| • | Concentrated arc for narrow, deep welds |
| • | High arc stability with challenging joint geometries |
| • | Precisely repeatable electrode replacement for consistent torch positioning |
| • | Different torch variants to suit available space, power requirements and materials |
Challenges in production
When high weld quality and short production times are required simultaneously, conventional TIG welding can reach its limits:
| • | Insufficient welding speed |
| • | Insufficient penetration or excessively wide welds |
| • | Arc deflection at flanges, corners and joints between components of different thicknesses |
| • | Time-consuming multi-pass welding and joint preparation |
What is needed is a process that reliably produces the required weld geometry within an economical processing time.
The solution: InFocus
Concentrated arc energy for productive welding processes
InFocus concentrates the arc energy through the interaction of torch design, electrode and intensive cooling. The higher energy density and increased arc pressure support deep penetration while keeping the weld narrow.
Depending on the material and welding task, the process can be configured for high-speed conduction welding or single-pass keyhole welding.
Technology & system configuration
Technological advantages
| • | InFocus 1000: torch current capacity of up to 1,000 A |
| • | Single-pass keyhole welding of sheets up to 10 mm thick with InFocus 1000 under suitable process conditions |
| • | Closed cooling circuit for high thermal load capacity |
| • | Screw-in electrodes for precisely repeatable replacement without regrinding or extensive adjustment |
| • | Favourable weld depth-to-width ratio; narrower heat-affected zones and reduced distortion are possible compared with conventional TIG welding |
The achievable results depend on the material, joint geometry and process parameters. The usable current of the complete system also depends on the power source, duty cycle and ambient conditions.
Modular system configuration
The torch, power source, cooling system and machine interface are combined to suit the welding task. Different InFocus variants are available:
InFocus 500
The slim torch design is suitable for confined spaces and welding currents up to 500 A – for example, in automated applications with limited access to the component.
InFocus 1000
The high-performance torch is designed for deep welds, keyhole applications and high-speed continuous welding processes.
InFocus Pluspole
The aluminium variant operates with direct current and an electrode connected to the positive pole (DCEP). The cathodic arc attachment on the workpiece continuously removes the oxide layer.
Under suitable conditions, single-pass aluminium welds up to 8 mm thick are possible without machined joint preparation. The torch is rated at 450 A at a 100% duty cycle under the gas conditions specified by the manufacturer.
Process expertise & control
A stable welding process requires the right combination of welding current, travel speed, torch position and shielding gas. The material, sheet thickness and joint geometry determine which combination is appropriate.
Support from OSCAR PLT
| • | Assessment of the welding task and selection of the torch variant |
| • | Development of conduction or keyhole welding processes |
| • | Adjustment of welding parameters and shielding gas supply |
| • | Evaluation of penetration, weld shape and thermal effects |
| • | Testing of process conditions for the planned automation |
Software & process control
Parameter settings and integration into your system
The power source provides the electrical process parameters and is connected to the motion system. Depending on the system configuration, the following options are available:
| • | Analogue, digital or customer-specific bus interfaces for machine control |
| • | Software for configuring power source parameters via USB |
| • | Optional sensors for torch guidance and height control |
| • | Camera systems for visual process monitoring |
| • | Additional cold-wire feeding; hot-wire and oscillating wire feeding are also available as equipment options for InFocus 1000 |
The range of functions is defined to suit the power source, motion system and welding task.
Applications
For automated longitudinal, circumferential and component welding
InFocus is suitable for joining applications where weld quality, penetration and productivity are equally important.
Typical applications
| • | Longitudinal seams on sheets, profiles and hollow sections |
| • | Circumferential seams on tubes and rotationally symmetrical components |
| • | Flange joints, corner joints and joints between components of different thicknesses |
| • | Continuous welding processes on thin-walled components |
| • | Aluminium joints with InFocus Pluspole |
Potential materials include high-alloy steels, duplex steels, nickel-based alloys, copper and titanium. Suitability is assessed for the specific joint.
