Robot Narrow Gap Hot Wire Argon Arc Welding

In recent years, with the development of welding industry and continuous improvement of welding technology, narrow-gap auto welding is attracting more and more attention. At present, the narrow auto welding system mainly adopt SAW welding and tungsten-rod TIG welding.

The advantages of narrow gap automatic welding are: reducing the amount of metal filling, saving a lot of welding materials and welding time, thereby greatly reducing the welding cost of the weld seam; The low heat input of the weld seam refines the microstructure of the welded metal and heat affected zone, improving the mechanical properties of the weld seam.

The narrow gap automatic welding system we produce consists of heavy-duty robots, wire feeding mechanisms, narrow gap welding guns (including swinging devices), welding equipment, etc.

The narrow gap automatic welding system is mainly applied in industries such as nuclear power, chemical equipment, pressure vessels, wind power, ships, bridges, petroleum, mining machines, etc.

The narrow gap automatic welding systems we exhibited at this Essen exhibition are mainly three types of robot narrow gap automatic welding systems, which are introduced as follows:

The robot narrow gap hot wire argon arc welding is composed of a heavy-duty welding robot, a hot wire argon arc welding machine, and a narrow gap welding gun.

Heavy duty welding robot, model: SYB1830B

Robot features: low noise, good linearity

Modular design, high reliability

High intelligence and security

Hot wire argon arc welding machine, model: DSP-400/RS

Hot wire argon arc welding consists of a welding power source, a hot wire power source, a water cooling system, and a vibrating digital wire feeder.

Welding machine features:

1. The welding machine and automatic wire feeder are both digitally controlled by DSP and communicate digitally.
2. The LCD menu touch screen function display of the welding machine and automatic wire feeder.
3. The wire feeder can choose from vibrating wire feeding, constant speed wire feeding, and pulsating wire feeding.
4. When vibrating wire feeding, it is beneficial to stir the melt pool and make the crystal grains finer,
5. Better mechanical properties of welds; Stir to remove volatile gases and bubbles from the melt pool,
6. Improved welding quality; The vibration function improves the welding ability at all positions; send
7. The molten droplets are easy to detach from the welding wire and enter the molten pool.
8. Automatic heating of welding wire, hot wire current: 10-200A;
9. The welding speed is more than twice that of a regular argon arc welding machine.
10. There are 30 storage channels

Narrow gap TIG welding gun

Suitable materials: carbon steel, low-alloy steel, stainless steel, etc

Suitable for narrow groove welding of 15mm or more

During welding, the wire swinging technique ensures that both sides of the groove are fully fused together

High deposition efficiency, low heat input

It can achieve various welding positions such as horizontal welding, vertical welding, and overhead welding
