According to ScienceDirect, hybrid laser welding combines laser welding with metal inert gas (MIG) welding techniques. The high-energy laser beam creates a heat source that contributes to producing deep weld.

MIG welding is a type of gas metal arc welding (GMAW) that simultaneously generates an electric arc between the workpiece and the wire electrode. It provides filler material for the welding process and improves the weld by reducing the chances of porosity. The release of shielding gas also contributes to preventing the weld from potential contaminants.

2. Laser-Plasma Arc Welding

This hybrid laser welding involves the integration of plasma arc with laser welding. Plasma arc generates high-energy welding arc by utilizing ionized gas. The high-energy plasma heats the workpiece, enabling the laser beam to penetrate the material.

The plasma arc in this hybrid welding offers better control over the heat input and improves weld pool stability. This technique is effective for welding thin plates and dissimilar materials that need controlled heat input.

3. Laser-MAG Welding

This technique involves the integration of laser welding with metal-active gas (MAG) welding. Like MIG welding, it also generates an electric arc using a wire electrode and workpiece. However, MAG welding involves active shielding gases.

According to TWI, MAG employs a mixture of carbon, oxygen, and argon. The use of active shielding gas helps to prevent contamination by removing oxides during the welding process. Laser welding produces intense laser beams to produce high input energy, resulting in the creation of deep welds. The combination of laser and MAG enables an efficient, deep-penetrating weld with minimal heat input.

4. Laser-TIG Welding

This hybrid welding integrates the tungsten inert gas (TIG) welding technique with the laser welding method. According to Wikipedia, TIG welding employs a tungsten electrode. The welding process doesn’t consume the tungsten. Instead, a filler material is used to complete the welding.

An inert shielding gas protects the weld from contaminants and oxidation. Generally, helium or argon is used as an inert gas. The combination of laser with TIG helps you enhance welding speed, boosting your productivity. This hybrid welding also improves joint quality, making it suitable for industries that demand high-end welds.

Process Advantages of Laser Hybrid Welding

Hybrid welding is a beneficial process, employing the features of arc and laser welding. It also enables you to overcome the limitations of both types of welding, contributing to improving the end product. Here are some advantages of laser hybrid welding:

1. Boost Welding Speed

Hybrid welding integrates the benefits of both laser welding and traditional welding methods and boosts welding speed. The laser machine generates a high-energy, intense laser beam as a heat source to vaporize the material instantly. Arc welding requires additional heat input, improving the fusion and deposition rate.

The hybrid process produces quicker and stronger welds. It improves the overall production rate of the welding process, making it an efficient process for high-volume production.

2. Boost Tolerance

Joint gap is a crucial aspect of welding processes, affecting the quality of welded joints. Joint gaps often deteriorate your weld, leading to defects and joint failures.

Employing hybrid welding allows you to improve tolerance to joint gaps. The combination of the heat input of the laser beam with the heat of arc welding allows you to prevent deviations in joint configurations during welding.

Hybrid welding offers you better welds that have 2 to 3 times more tolerance than laser welding. The improved tolerance of hybrid laser arc welding minimizes post-welding distortions, making it a versatile choice for industries that require greater precision.

3. Increased Single Pass Penetration Depth

Hybrid laser-arc welding also enables you to achieve increased single-pass penetration depths. The intense and focused energy from the laser beam facilitates deep penetration into the material.

The laser beam, along with arc welding, allows deeper penetration of the joint. The high energy of two welding techniques combined creates an intense heat source that results in increased single-pass penetration depths. This feature is necessary for industries that involve the welding of thicker materials. It also contributes to strengthening the weld, making it more durable and resistant to stress.

4. Improved Weld Quality

The quality of the weld is imperative for various industries. It is also necessary to craft durable products. However, creating a quality weld is a daunting task due to the complexity of the welding process and the potential for defects.

Hybrid laser welding offers a convenient way to improve the weld quality. Laser welding offers you precise control over the welding process. It offers you a narrow weld bead, allowing you to minimize the distortion. The synergistic effects of laser and arc welding techniques reduce the risks of porosity and distortion in the weld.
