Architectural & Industrial Metal Finishing Streamlining Fabrication: Laser Beveling Innovations 

As discussed in “Beveling edges on metal plate, sheet metal with a laser cutting machine” on The Fabricator, achieving optimal weld quality begins with the beveling process, especially when preparing sheet metal for welding. Emphasizing the significance of precise bevel cuts for robust and stress-resistant welds, a critical aspect of weldment production is the homogeneity of the bevel cut. A uniform cut, particularly in inclination angles, ensures automated welding meets stringent quality standards. Inconsistencies might necessitate manual welding for precise control over the fill metal flow.

Beveling With a Laser:

Aligning with the industry’s cost-minimization goal, the integration of cutting and beveling operations into a single step is key. Laser cutting machines with 3D heads and five interpolated axes efficiently perform beveling, hole drilling, and marking in a seamless cycle, eliminating the need for additional post-processing steps like drilling and edge cleaning.

X Beveling With a Laser:

The 3D bevel head, with a rotation and tilt of up to 45 degrees, excels in cutting various bevel shapes, including internal contours, variable bevels, and multiple bevel contours (Y, X, or K). The X bevel, crucial in shipbuilding and defense applications, proves essential for welding one-sided pieces, particularly sheets up to 1.47 in. thick.

In tests on grade S275 steel plate, the demonstrated superiority of laser cutting in producing top bevels with precise angles and reduced heat-affected zones enhances the final welding outcome.
