Hongming Sheng manufactures custom welded metal assemblies, fabricated brackets, frames and structural subassemblies according to customer drawings and engineering requirements.

We support TIG welding, MIG welding, robotic welding, laser cutting, CNC bending, machining, grinding, surface finishing and final mechanical assembly.

Welding Fabrication Capability

Welding methods and fabrication sequence are selected according to part geometry, material, thickness and assembly requirements.

• TIG welding
• MIG welding
• Robotic welding
• Spot welding when applicable
• Fixture-assisted welding
• Grinding and weld finishing

Custom Welded Metal Assemblies

• Equipment support brackets

• Custom steel and aluminum welded parts

From Individual Parts to Finished Assembly

Many welded projects require multiple fabricated parts to be positioned and joined into a finished assembly.

Assembly Fit & Welding Sequence

For welded assemblies, part positioning and welding sequence can affect final dimensions and fit.

• Joint and weld location review
• Fixture and positioning requirements
• Welding sequence planning
• Heat distortion consideration
• Critical mounting point control
• Assembly gap and interface checks
• Post-weld machining when required

Materials & Finishes

Typical Applications

• Industrial automation equipment
• Robotics systems
• Electrical equipment
• Energy storage equipment
• Production machinery
• Equipment mounting structures
• Industrial housings and frames

Quality Inspection

• Material and thickness verification
