In the production and processing process, many parts and components will have a specific angular groove process due to design and structural requirements. This is essential in industries such as automobile manufacturing, industrial and agricultural machinery, shipbuilding, and more. The groove processing operation is necessary for the final welding process. The groove to be welded is machined in a groove shape to achieve full penetration at the welding thickness.

Traditionally, the groove processing operation was carried out using techniques like flame and plasma cutting. Common groove types included V-groove, U-groove, X-groove, K-groove, and Y-groove. However, these methods often produce deeper cuts during groove cutting, increasing the risk of incomplete welding. Grooves exceeding 3 mm usually need to be carefully processed. In critical areas, these grooves can only be removed using grinding, and repair welding is generally not allowed. If there are imperfections, the subsequent process becomes very laborious. Additionally, flame and plasma processing are considered high-energy operations, causing metal plates to be prone to thermal deformation. Post-groove processing requires a reverse deformation process, which presents another significant challenge.

The fiber laser cutting machine is a new groove processing method that minimizes thermal deformation and provides the best cutting quality. The laser groove cutting machine can process steel plates up to 25 mm and complete various shapes like V, X, Y, K, and others in a single pass. Compared to traditional flame and plasma groove processing, laser groove cutting significantly enhances processing efficiency, ensures groove quality, and reduces material waste. For example, in shipbuilding, laser groove cutting is used to process low-alloy steel T-shaped members, ensuring the stability of the ship while achieving significant weight reduction.
