Backed by an in-house R&D team, Huayan designs and manufactures custom automated welding & hardfacing equipment. Our systems support a wide range of materials: carbon steel, stainless steel, low-temperature alloy, aluminum, copper alloy and Stellite overlay alloys.
We adopt modular machine architecture. BWG, LS, WS, CZ series special welders, positioners, saddle welding machines, laser & plasma cladding units and robot workstations can be freely combined to match your workpiece dimension and production flow.
Our equipment serves valve, pressure vessel, offshore pipeline, petrochemical and mining industries. Built-in IoT remote diagnosis function allows our engineers to check machine status, analyse alarms and optimise welding parameters online, cutting downtime and overseas service costs.
Case highlight: We delivered modular cladding & girth welding stations for multiple valve manufacturers. The automated hardfacing solution improved overlay uniformity and reduced rework rate for Stellite seat surfaces.
We provide full lifecycle technical support from process testing, equipment commissioning to operator training.
