Hongming Sheng provides precision metal welding and custom fabrication services for brackets, frames, enclosures, housings and welded assemblies according to customer drawings.

We support TIG / MIG welding together with laser cutting, CNC bending, machining, grinding, finishing and mechanical assembly for custom metal components.

TIG & MIG Welding

Welding method is selected according to material, thickness, structure and appearance requirements.

• TIG welding for aluminum, stainless steel and detailed assemblies
• MIG welding for steel and structural fabrication
• Spot welding when applicable
• Continuous or intermittent welds according to drawing requirements
• Weld grinding and surface preparation when required

Custom Welded Components

• Sheet metal brackets and supports
• Industrial enclosures and housings
• Welded machine frames
• Equipment bases and structural assemblies
• Battery and energy system structures
• Robotics and automation components

Fabrication Before & After Welding

Welding is often only one step in a complete fabrication process. We can combine multiple manufacturing operations according to the finished part requirements.

Key Engineering Points

Welded structures need to be reviewed for more than weld appearance. Part geometry and assembly fit are also important.

• Joint design and weld location
• Material and thickness combination
• Heat distortion and deformation control
• Fixture and positioning requirements
• Overall dimensional stability
• Post-weld machining requirements
• Assembly and mounting interfaces

Materials

Typical Applications

• Industrial equipment
• Machine frames and bases
• Sheet metal enclosures
• Automation equipment
• Robotics structures
• Battery and energy equipment
• Electronic equipment housings
• Custom support brackets

Quality & Dimensional Inspection

• Material and thickness verification
• Critical dimensional inspection
• Weld position and appearance checks
• Hole and mounting position verification
• Flatness and straightness checks when specified
• Assembly fit verification when required
• Final visual inspection before shipment

Prototype & Repeat Production

We support prototype builds, sample validation and repeat manufacturing for custom welded components and assemblies.

Prototype assemblies can be used to verify welding sequence, dimensional stability and fit before production quantities increase.

What to Send for Quotation
