A tube is only as strong as its weld, and inconsistent fusion from tube-type or worn welders leaves weak seams that split in bending or leak in service. Mills chasing stable weld quality on φ10-26mm thin-wall tube need repeatable, controllable heat input.
Older or under-powered welders struggle to hold heat input as line speed and wall thickness change, so the seam over- or under-fuses. Without positive seam guidance the edges drift off-center, and inconsistent squeeze pressure leaves voids or excessive flash at the weld.
A 100 kW solid-state HF welder delivers stable, adjustable heat across the full φ10-26mm / 0.4-1.5mm range, holding consistent fusion at up to 90 m/min.
Dedicated seam guidance locks the edges before squeeze rolls complete fusion, and adjustable squeeze pressure matches the wall for a clean, strong weld.
Automatic outside-burr removal then clears the bead, so the welded tube moves cleanly into sizing without surface defects.

|---|---|
| Tube outside diameter | φ10–26 mm |
| Wall thickness | 0.4–1.5 mm |
| Rated production speed | up to 90 m/min |
| Raw material | HR / CR low-carbon steel, galvanized steel |
| HF welder power | 100 kW solid-state |
| Forming stands | 5 rough + 3 finish |
| Sizing stands | 6 horizontal + 6 vertical |
| Leveling rolls | 7-roll precision leveler |

| Coolant flow | ≥10 t/h spray + overflow pool |
| Roll shaft material | 42CrMo quenched & tempered + HF hardened |
Every ZY20 runs one continuous flow from coil to finished cut tube. An uncoiler feeds strip through a 7-roll precision leveler that removes coil-set, then double-radius forming shapes it in 5 rough and 3 finish stands without edge wave. A 100 kW solid-state HF welder fuses the seam under squeeze pressure with a dedicated seam guide, and an automatic outside-burr unit clears the bead immediately. ≥10 t/h spray plus overflow-pool cooling locks the shape, the 6-horizontal + 6-vertical sizing train sets the diameter, and a 4-roll Turk head straightens the tube before the microcomputer flying saw cuts 4–8m lengths to ±3mm. Overload-protected stands and 42CrMo hardened shafts keep the whole line stable over long runs.
Welded steel tube for furniture, structural, precision and galvanized applications where a strong, repeatable HF weld is the critical quality driver.
Confirm your wall range and speed, then verify the welder power (100 kW solid-state on the ZY20) covers your material mix. Check seam guidance and squeeze control for repeatable fusion, and confirm cooling capacity after the weld.
The ZY20 ships as a turnkey package with layout and foundation drawings so you can prepare the site before delivery. Engineer-led on-site installation and commissioning bring the line to rated output, with operator training to hand over a running mill. A one-year warranty with spare-parts support protects the investment, and because the line accepts HR, CR and galvanized coil, you can adapt to changing material costs and market demand without re-tooling.
Solid-state output is stable and adjustable, giving repeatable fusion across the wall range.
A dedicated seam guide positions the edges before squeeze welding.
100 kW solid-state, sized for φ10-26mm and 0.4-1.5mm at 90 m/min.
