Chamfering technology enters the era of lasers
In metal welding pretreatment, traditional edge chamfering usually relies on processes such as plasma cutting, milling, or grinding. However, with technological advancements, advanced laser cutting systems have become a better solution. It can not only complete this task, but also achieve high-quality chamfering with faster speed, cleaner cutting surface, and high consistency, marking an important leap in the process.
What Is Beveling?
Beveling refers to cutting an edge at an angle (usually 30°–45°) to prepare a part for welding. It:
Improves weld strength and penetration
Reduces the risk of slag, poor fusion, or misalignment
Is essential in industries like pressure vessels, steel structures, and shipbuilding
Plate vs Tube Bevel Cutting: What’s the Difference?
Plate Bevel Cutting with Lasers
Key Benefits:
±45° angle support with rotary laser head
One-pass cutting without repositioning
Superior precision and repeatability
Applications:
Pressure vessel fabrication
Steel structures and heavy machinery
Bridge components and rail systems
Tube Bevel Cutting with Lasers
Key Benefits:
Supports straight or complex bevels on circular and square tubes
Automatically adapts to angled or curved surfaces
High consistency for saddle cuts, slanted joints, or fish-mouth shapes
Applications:
Construction piping
Shipbuilding and chassis structures
Prefabricated pipe modules and robotic welding
Common Bevel Types
Limitations of Traditional Beveling
Before laser beveling, companies relied on:
Plasma bevel machines
Manual grinders
CNC milling or edge trimming machines
These methods have significant downsides:
Low precision and angle consistency
Multi-step processing and material repositioning
High labor intensity and safety concerns
Difficult to automate, large footprint on shop floor
Why Choose Laser Bevel Cutting?
Modern laser cutting systems equipped with beveling capabilities offer a smarter solution:
One-Step, Multi-Angle Cutting
With advanced bevel heads (±45° rotation), laser machines can cut bevels directly without flipping or re-fixturing the sheet.
High Precision and Consistency
Laser beams offer a narrow kerf and precise energy control, enabling accurate bevel angles.
Seamless Welding Prep
Laser-cut bevels produce clean edges, eliminating the need for secondary grinding or edge cleaning before welding.
When Should You Consider Laser Bevel Cutting?
You require complex bevel angles or batch production
You aim to automate welding prep or upgrade from manual methods
You want to reduce workforce dependency and error rates
