Laser Beveling Engineering Standards

Laser Weld Bevel Cutting Parameters Matrix (V / Y / K / X Bevels)

Precision weld beveling directly from laser cutting eliminates manual plasma gouging and robotic weld seam tracking failures. This matrix provides certified cutting speeds, bevel angles, and gas pressures across heavy plate thicknesses.

1. Carbon Steel (Q235B / Q345B) Laser Bevel Cutting Parameters

Plate Thickness (mm)	Bevel Type & Angle	Laser Power (kW)	Cutting Speed (m/min)	Assist Gas & Pressure	Root Face Tolerance
12 mm	V-Bevel (30°)	15 kW	3.2 – 3.8 m/min	O2 (0.6 – 0.8 Bar)	±0.15 mm
20 mm	Y-Bevel (45° + 2mm Root)	20 kW	2.0 – 2.5 m/min	O2 (0.5 – 0.7 Bar)	±0.20 mm
30 mm	K-Bevel (Double 35°)	30 kW	1.2 – 1.6 m/min	O2 (0.4 – 0.6 Bar)	±0.25 mm
50 mm	X-Bevel (Double 45°)	40 kW – 60 kW	0.8 – 1.1 m/min	O2 (0.4 – 0.5 Bar)	±0.30 mm

2. Robotic Weld Seam Integration Best Practices

Using ACTCNC high-torque 5-axis beveling heads ensures consistent focal positioning even during severe thermal expansion, feeding certified submerged arc welding (SAW) and robotic MIG cells with zero manual rework.
