What Is Laser Welding Technology?

Besides cutting, another important sector in metal fabrication is laser welding technology. Welding is essential to industries like shipbuilding, where many metal pieces must be combined for the basic ship structure.

Welding means joining two or more metal pieces together. Traditional welding, like arc welding, requires excessive physical effort, pressure, and proper technique. Laser welding machines are modern machines that do not require any pressure or physical effort while welding.

These are precise machines that work effortlessly even if the operator is not skilled enough, as they require very minimum physical effort. Laser hybrid welding machines give high-quality welding, especially for types of welding like T-joints pipe joining or butt and fillet welds, or complex joint configurations that are easy to perform by laser welding machines. 

Why Is Laser Beam Welding Important in Shipbuilding?

Laser welding has numerous benefits. These high-quality machines are fast and can cope with the rapid production volume of the shipbuilding industry. Besides these, they are efficient and require less manual handling as in other traditional welding techniques. 

Laser welding processes work with high-quality beams. Just like laser cutting, the contact zone of the laser beam and material is on-spot and very narrow. The concentrated energy of the laser only affects the part where it is directed without distortion or material loss.

These powerful welding machines are equipped with high-power energy that can melt even the hardest of materials in a fraction of the time.

Common Welding Imperfections in Shipbuilding

Laser welding machines can weld different types of material with precision. Here are some challenges that welders may feel in the shipbuilding industry:

1. Lack of Fusion

A major problem welders face is the lack of fusion. It happens when the workpiece does not fuse adequately with the base material. Almost the whole ship structure depends on strong welding. A laser cutting machine can fuse even dissimilar materials with perfection.

2. Porosity 

It is another imperfection that the shipbuilding industry faces. It happens when gas pockets or voids form while welding two materials. Porosity may cause cracks and weak joints.

3. Welding Cracks

It happens when the heat affects the surrounding materials. The laser beam is highly focused and heats only the area where it is directed. It does not affect the surrounding material. The laser beams can melt and join the most challenging materials like steel springs, carbon steel, or aluminum.

4. Undercut

An undercut or groove is formed at the edge of the weld joints. Undercuts can reduce welding strength. We have also prepared an article for you evaluating welded joints.

5. Distortion

Distortion also happens while welding sensitive materials. Excessive heat can melt or distort the surrounding materials. Distortion can affect the dimensional accuracy, weakening the structure or ship.
