WELDING THICK SECTIONS
Advantages
Civan Lasers' dynamic beam laser technology is revolutionizing thick section welding, offering unparalleled efficiency and quality. Traditional challenges in welding thick materials, such as LACK OF FUSION, porosity, and distortion, are effectively addressed. Dynamic beam shaping enables real-time adjustments to the beam profile, optimizing heat distribution for deeper penetration and enhanced weld strength. This innovative approach minimizes defects, reduces post-processing requirements, and increases productivity, making it ideal for industries like shipbuilding, aerospace, and heavy manufacturing. With Civan's dynamic beam lasers, welding thick sections is no longer a limitation but a gateway to superior performance and reliability.
Penetration Depth: Single pass weld of up to 73mm, the large penetration depth allows to reduce the number of passes and helps to reduce heat input, welding time and eliminates lack of fusion challenges.
​
Heat Input: The low heat input that is in the laser process leads to smaller Heat Affected Zone and
HOW IT WORKS
Utilizing sequence beam shape allows to control the melt pool dynamics and overcome solidification carck and porosity. The beam shapes used in the sequence and the duration of each beam shape needs to be optimized for each process, but works for most applications.
CASE STUDY
One of the most exciting real-world applications of Dynamic Beam Laser technology is in the shipbuilding industry. Fincantieri S.p.A., a leader in high-value ship construction, is collaborating with Civan Lasers to test DBL for welding thick sections of steel.
Traditionally, Fincantieri used a combination of Hybrid Laser and MIG/MAG processes for welding, but these methods have limitations in terms of speed, energy consumption, and the maximum thickness they can weld. Through their open innovation approach, Fincantieri is testing DBL to overcome these challenges.
The early results of this collaboration have been promising:
-
40% Increase in Welding Speed: The introduction of DBL has accelerated the welding process, making production more efficient.
-
Ability to Weld Thicker Sections: DBLs can handle materials that are over twice as thick as those welded by traditional methods, expanding the possibilities for ship design and construction.
-
60% Energy Reduction: With less energy required, the process is not only more cost-effective but also aligns with the industry’s sustainability goals.
-
90% Reduction in Filler Material Use: The significant drop in filler material consumption drastically reduces costs, streamlining production.
-
Minimized Use of Protective Gases: Protective gases, which are typically used in large quantities, are no longer a major cost factor.
