[Breaking Through Together: Shanghai Hugong and Hangshun HK32MCU Racing in the High-End Welding Machine Blue Ocean]
In 2025, the global electric welding machine market size is expected to exceed 20 billion USD, with high-end digital welding machines becoming the fastest-growing segment. Facing the long-term dominance of foreign brands in the high-end market, domestic leader Shanghai Hugong decisively partnered with the leading domestic 32-bit MCU provider Hangshun Chip, using the HK32MCU as the "digital engine" to launch a new generation of digital welding machine series. Within just a few weeks of launch, orders surged dramatically, successfully entering high-end scenarios with extremely high reliability requirements such as shipbuilding and offshore engineering equipment, becoming the first to "break the ice" in the domestic high-end welding machine market.
[Three Major "Core" Energies Injected into Shanghai Hugong by Hangshun HK32MCU]
