Steel Sheet Material Laser Cutting, Bending, and Welding Flow Chart.
This flowchart represents the step-by-step process of fabricating steel sheet components using laser cutting, bending, and welding techniques.
Raw Material Preparation
- Selection of appropriate steel sheet (Mild Steel, Stainless Steel, etc.)
- Material thickness verification
- Cleaning and surface preparation
Laser Cutting Process
- Programming & Design
- Import CAD files into CNC laser cutting machine
- Set cutting parameters (power, speed, gas type)
- Cutting Execution
- Precision laser cutting as per the design
- Removal of dross and burrs
- Quality inspection of cut parts
Sheet Metal Bending (Press Brake Operation)
- Tooling Setup
- Selection of the correct bending die and punch
- Machine calibration
- Bending Process
- CNC press brake applies force for accurate bending angles
- Multi-stage bending (if required)
- Measurement and inspection of bends
Welding Process
- Edge Preparation
- Grinding and cleaning of edges for welding
- Alignment and clamping of parts
- Welding Execution
- Selection of welding method (MIG, TIG, Spot Welding, etc.)
- Controlled heat application to avoid warping
- Quality check for defects (cracks, porosity, misalignment)
- Post-Weld Treatment
- Grinding and smoothing weld joints
- Stress-relief treatment (if necessary)
Surface Finishing & Coating
- Deburring and polishing
- Surface cleaning (sandblasting, pickling)
- Powder coating, painting, or galvanization (if required)
Final Inspection & Quality Control
- Dimensional accuracy check
- Weld strength testing
- Visual and functional inspection
Packaging & Dispatch
- Protective packaging for transport
- Labeling and documentation
- Shipment to the customer or next stage in the production proces
