Welding Solutions to Achieve High Quality & High Speed Automation
KOBELCO offers welding solutions package, original welding process integrated with welding robot system and welding consumables
Ultra High Current GMAW welding process
Ultra High Current GMAW welding process (Approx. 2 minutes)
Ultra-high current GMAW welding process provides high efficiency
Ultra-high current MAG welding process provides high efficiency. Double productivity of conventional single arc, and same as tandem arc process.
Spray arc provides low spatter, even at high current
Low spatter and stable arc has been achieved with Ultra high current GMAW process and MX-A100D specially designed for this process.
Deep Penetration
Obtain deeper penetration than conventional process.

Features of Ultra High Current GMAW welding Process / the Tandem MAG welding process
Ultra High Current GMAW welding process, with single torch, promise wide application of robot welding with easy teaching and handling.
| Ultra High Current GMAW welding process* | Tandem MAG welding Process* | |
|---|---|---|
| Deposition rate | Better | Better |
| Spatter generation | Better | Fair |
| Welding speed | Good | Better |
| Penetration | Better | Fair |
| Handling | Better | Fair |
| Gas Cost | Better | Fair |
Configuration of ultra high current GMAW process
- Welding Robot ARCMAN™ MP
- Welding wire FAMILIARC™ MX-A100D 1.4mmΦ
- Welding Power Source SENSARC™ AB500
Tandem Arc Welding System
Features
- Tandem welding reduces the cycle time by about 40% compared to single welding.
- Advanced Lord Characteristic Control and Synchronous Amplitude Modulation Control function ensures stable arc and lower spatter welding.
- Dual Arc Sensor detects the difference in the amperage of the leading and the trailing wire and adjusts the alightment of the leading wire as well as correct the misalignment of the trailing wire during welding. This function significantly improves the welding quality and reduces the need for repair welding.
Efficient Horizontal Fillet Welding with CB controller
Features
- Able to achieve high speed horizontal fillet welding with single arc, 6mm leg length at 700mm/min, without undercuts and overlaps.
Able to simplify positioner by changing welding position from Flat positon to Horizontal Fillet position.
Function
- Setting arc voltage at vertical and flat member sides independently
- Changing weaving direction
Cofigulation
- Manupilator: ARCMAN™ GS, ARCMAN™ MP
- Robot Controller: CB Controller
- Welding Power Source: SENSARC™AB500
Laser Root-Gap Detection System
Features
- Able to apply various figures, even detect the root-gap at flare and T-joint
- Able to reduce detection time by around 60% comparing to wire touch sensing
- Able to detect more precisely than wire touch sensing
Welding Robot System with Preheating Device
It offers fully automatic preheating and welding;
- Switching between welding torch and preheating device
- Iginiting and fire extinguishment
- Detecting completion of preheating with sensor and proceed to welding
