Hull and deck structures are the core components of a ship, including bottom plates, side plates, deck plates, and large reinforcement members. These parts are typically very large, thick, and require bevel preparation for welding. Traditional plasma or flame cutting causes large heat-affected zones and thermal deformation. Dimensional errors during plate cutting can lead to severe problems during block assembly and watertight welding. High-power fiber laser cutting provides a narrow heat-affected zone, high precision, and one-step beveling, significantly improving the efficiency and quality of ship hull construction.

| Item | Plasma / Flame Cutting | Fiber Laser Cutting |
|---|---|---|
| Heat-Affected Zone (HAZ) | Large HAZ, high risk of thermal deformation | Narrow HAZ, minimal thermal deformation |
| Bevel Preparation | Separate machining process, low efficiency | One-step V/Y groove forming, high efficiency |
| Cutting Edge Quality | Rough edges, requires extensive grinding | Smooth edges, ready for watertight welding |
Q1: Can fiber laser cut thick hull plates over 20mm?
A: Yes, with high-power laser sources (12000W-30000W), we can efficiently cut thick marine-grade carbon steel with high quality.
Q2: How does laser cutting handle the bevel for welding?
A: Equipped with a specialized bevel cutting head, the laser can complete the V-groove or Y-groove in one step while cutting the contour, saving a separate machining process.
Q3: Is the heat-affected zone small enough to prevent ship plate deformation?
A: Absolutely. The focused laser beam results in a very narrow heat-affected zone, significantly reducing thermal deformation compared to plasma or flame cutting.
