Semi-Auto Shear & Butt-Weld Joiner
Keep the line feeding across coil changes. Operators should focus on square ends, weld bead, and grind flush—so joins don’t print into formed product.

Operation steps
Stage coil ends at the joiner
Stage coil ends at the joiner
Bring outgoing tail and new head into the 400 mm window. Tag CS vs GI—coating burns differently.
Square-shear both ends
Square-shear both ends
Semi-auto shear step. Out-of-square faces force a tall bead—gate with a square before weld.

Bead height and porosity. specification is butt-join for continuous feed.
Grind / plane flush
Grind / plane flush
Join must clear roll stands and punches. Confirm flushness before releasing the line.

If dual-head decoilers ship in the same order, cut to the decoiler page—don’t paste 4 T / 50 m/min decoiler claims here.
Key details
Note 1
Publish millimetres. A literal 400 m strip width is a transcription fail for a 400-class joiner.
Line speed
Same order’s dual-head decoiler (4 T / remote rotate / ~50 m/min class) is a different specification—keep numbers off this table.
