Technical Parameters

Product Uses

1. Pharmaceutical & Food Clean Piping Industry:

Hygienic stainless steel pipe butt welding for pharmaceutical equipment, pure water production lines, and dairy processing equipment. The inner walls of clean pipes are free of oxidation, meeting GMP hygiene standards, paired with closed-type pipe welding machines for automatic root welding of thin-walled clean pipes.

2. Nuclear Power & Military Special Equipment:

Precision automatic TIG welding for nuclear instrument tubes, heat exchanger pipelines, and military special alloy pipe fittings made of titanium/high-temperature alloys. Strict flaw detection conditions and precise stable current power supply ensure weld qualification.

3. Petrochemical & Coal Chemical Industry:

Automatic butt and flange circumferential welding for chemical plant heat exchangers, high-pressure vessels, and stainless steel oil & gas pipelines. Suitable for thick-walled, high-pressure components with multi-pass fill and cap welding.

4. Boiler & Pressure Vessel Manufacturing:

Welding of boiler heat transfer tube bundles, various storage tanks, and heat exchanger pipe openings. Automatic welding of batch tube sheets and flanges, suitable for factory assembly line mass production.

Product Operate Guide

1. Wiring Inspection

Connect the 380V industrial input power, welding machine head control cables, argon gas pipes, and water cooling pipes (for water-cooled models). Ensure that the cables are undamaged, the water circuits have no leaks, and gas valves are closed.

2. Head Matching

Connect and lock the corresponding pipe welding machine head (AT8/AT40/AT80, etc.) to the power interface. Verify the head specifications and the outer diameter and wall thickness of the pipe to be welded.

3. Fixture and Pipe Installation

Clamp the pipe in the chuck/closed head, align the pipe ends evenly, ensure offset edges meet process requirements, and lock the head claws.

4. Close the main power switch, power on the equipment, and the 7-inch touchscreen will enter the main operation interface.

5. Gas and Water Testing

Open the argon gas cylinder valve and set the protective gas flow; for water-cooled models, start the water circulation and confirm normal circulation with no water shortage alarms.

6. Briefly press the jog button on the interface to make the head rotate slightly, checking that travel and welding gun swing are smooth and not stuck.

7. Small-section test welding: observe arc stability. If the arc is too long or short, adjust the arc length parameter on the touchscreen; if there is excessive spatter, adjust the current.

8. Once the parameters are confirmed correct, press the touchscreen to start welding. The equipment first pre-purges argon to expel air in the pipe, then the head automatically rotates to strike the arc, completing root/pass and fill/cap layers according to the preset program.

9. After completing the full-circle weld, the equipment automatically delays closing the protective gas to prevent high-temperature weld oxidation.

10. When the head stops rotating, shut down the equipment operation program → turn off the touchscreen → cut off the main power and close the argon gas valve.
