Precision Manufacturing for Thick Plates
Challenges in Processing Thick Plates
The manufacturing of heavy machinery—such as excavators, cranes, agricultural tractors, and mining equipment—relies heavily on the processing of thick steel plates. These components must withstand extreme loads and harsh environments.
Historically, this sector depended on flame cutting and plasma cutting. While effective for basic separation, these thermal processes often introduce significant thermal distortion and result in tapered edges (bevels) that require extensive secondary machining and grinding before welding can occur. This bottleneck significantly slows down the assembly process.
High-Power Laser Revolution
The advent of high-power fiber laser cutters (10kW, 20kW, and beyond) has transformed heavy industry. Today, lasers can cut through 30mm, 40mm, or even thicker carbon steel plates with remarkable speed and edge quality.
The verticality of the cut edge is far superior to plasma, allowing for tighter fit-up tolerances during assembly. This precision is critical for the structural integrity of large frames and booms.
Optimizing the Welding Workflow
In heavy machinery, welding is the most time-consuming phase. By utilizing laser cutting, manufacturers receive parts that are "weld-ready." The precision of the cut reduces the gap between joining parts, meaning less filler material is needed and welding speeds can be increased.
Furthermore, advanced laser machines can perform bevel cutting in a single pass, preparing the plate for welding immediately.
Haisinn Laser’s high-power solutions are designed to handle the rigors of heavy plate processing, helping manufacturers build stronger machines faster.
