China's Welding Robots Beat Fanuc & Yaskawa: Estun's 10,000-Robot Quarter

The quarter that broke the four-family grip

The "four families" — Fanuc (Japan), Yaskawa (Japan), ABB (Switzerland) and KUKA (Germany) — defined industrial robotics in China for two decades, and welding was their fortress: automotive lines demanded arc consistency, repeatability and safety certifications that only they seemed to hold. That ended quietly. In 2025 Estun took the top spot among all brands in China, local and foreign, with ~10.6% share and ~25% annual shipment growth. By Q2 2026 it shipped more than 10,000 robots in a single quarter — a first for a Chinese brand — and has now led domestic-brand shipments for eight straight years. Inovance, Siasun and EFORT are close behind.

Why welding was the beachhead

Welding is the right beachhead for a domestic challenger: it is high-volume, repetitive, and less demanding than aerospace or microelectronics precision, yet it rewards deep application engineering. Estun's decisive move was acquiring Cloos, the German arc-welding specialist, giving it world-class welding know-how overnight. It then vertically integrated the rest of the stack — own servo motors, motion controllers and drivers — which let it price a complete welding cell at roughly 60–70% of a Fanuc/Yaskawa equivalent and win the fast-growing EV, photovoltaic, energy-storage and lithium-battery lines that need local service within hours, not weeks.

The scoreboard: China market share 2026

Where the foreigners still win

The decline is a volume story, not a total-victory story. Fanuc and Yaskawa still lead in the highest-precision niches — luxury automotive body-in-white, semiconductor handling, and the tightest tolerance cells where decades of motion-control IP and global service networks matter. ABB's exit looks like a retreat, but SoftBank's robotics bet (it also owns Boston Dynamics) signals consolidation rather than abandonment. KUKA's Midea ownership makes it, effectively, a Chinese competitor with a German brand. The realistic read: Chinese robots won welding and general handling; foreign brands hold the precision crown, and that split is now the baseline assumption for any automation buyer.

What it means for buyers

• Cost: a six-axis Chinese welding robot runs roughly 60–70% of a comparable Fanuc/Yaskawa, and total installed cost is lower still with local engineering.
• Speed: EV/PV/lithium lines iterate fast; local suppliers deliver service, cells and changes in days versus weeks.
• Caveat: for the tightest automotive and semiconductor cells, verify cycle-time accuracy and certification before defaulting to the cheapest option.

Frequently asked questions

Who is the largest industrial robot maker in China now?

Estun Automation led all-brand industrial-robot shipments in China in 2025 with about 10.6% share, and in Q2 2026 became the first domestic brand to ship more than 10,000 robots in a single quarter (MIR DATABANK).

What happened to Fanuc, Yaskawa, ABB and KUKA in China?

Fanuc's China share fell from a peak above 20% to around 9%; ABB sold its robotics business to SoftBank for about $5.375B; KUKA, owned by Midea since 2016, keeps roughly 10%. Combined domestic-brand share in China has passed 56%.

Are Chinese welding robots as good as Fanuc or Yaskawa?

For high-volume welding, sheet metal, PV and lithium-battery lines, Estun (which acquired Cloos), EFORT and Siasun match foreign specs at lower cost and faster local service; foreign brands still lead the highest-precision automotive and semiconductor niches.

Why did Estun overtake the foreign families?

Vertical integration (its own servo motors and controls), pricing at roughly 60–70% of foreign robots, local welding-engineering capability, and EV/PV/new-energy demand that rewards fast local support.
