Hongming Sheng manufactures custom welded metal structures, industrial frames, machine bases and fabricated assemblies according to customer drawings, CAD files and engineering requirements.

Our fabrication capabilities include TIG welding, MIG welding, robotic welding, laser cutting, CNC bending, machining, grinding and final assembly.

Industrial Welding & Fabrication

Welded industrial structures often require more than basic joint strength. Overall geometry, mounting interfaces and dimensional stability are also important.

• TIG welding
• MIG welding
• Robotic welding
• Fixture-assisted welding
• Grinding and weld finishing
• Post-weld machining when required

Custom Welded Structures We Manufacture

• Industrial machine frames
• Equipment bases and support structures
• Welded brackets and mounting assemblies
• Electrical equipment frames
• Battery and energy system structures
• Automation equipment structures
• Custom steel and aluminum assemblies

Fabrication Process

Deformation & Dimensional Control

Heat input during welding can affect straightness, flatness and mounting positions. For structural parts, manufacturing sequence and fixture design should be considered before production.

• Weld sequence planning
• Fixture and positioning control
• Heat distortion consideration
• Critical hole and mounting point verification
• Flatness and straightness checks when specified
• Post-weld machining for critical interfaces when required

Materials

Surface Finishing

• Powder coating
• Painting
• Brushing
• Polishing
• Anodizing for aluminum parts
• Galvanizing when specified
• Other project-specific finishes

Industrial Applications

• Industrial automation equipment
• Robotics systems
• Production line equipment
• Machine frames and bases
• Energy storage equipment
• Power equipment
• Electrical and control systems
• Testing and inspection equipment

Quality Inspection

• Material and thickness verification
• Overall dimensional inspection
• Weld position and appearance checks
• Critical mounting position verification
• Flatness and straightness checks when specified
• Surface appearance inspection
• Final assembly fit verification when required

Prototype & Repeat Production

We support prototype builds, trial assemblies and repeat manufacturing for custom welded structures.

Prototype fabrication can help verify weld sequence, structure fit, mounting positions and assembly before production quantities increase.

What to Send for Quotation

• 2D drawing or 3D CAD model
