Types of Laser Welding
Continuous Beam Laser Welding
The lasers used in this type of welding are called as continuous beam or constant wave or continuous wave laser. These lasers are an excellent choice for speedy seam welding applications. This welding process utilized a continuous laser beam of light. This process is acceptable for deep penetration welds. Two things i.e., power and feed speed must be accurately balanced.
This type of welding is used in the sheet metal and automotive industry such as automotive steering welding. It is used for metals like stainless steel, aluminum, copper, etc.
Spot Welding
Spot welding gives quick outcomes. It is well known for its speed and when we need to join two pieces of material together. This process is an easy method and doesn’t need any shielding gas.
Seam Welding
It is a method where similar or dissimilar metals are joined at the seam. In the seam welding process, welding current is the major parameter. The welds created by this method are airtight.
Wobble Welding
LBW which is the latest welding technology proffers the greatest features and advantages. The wobbling technique or laser beam oscillation is excellent. It can be used for good quality welding even when there is a gap between welding sections.
During the welding process, this technique functionally increases the diameter of the beam to increase the breadth of the weld. An increase in effectual beam diameter is due to superimposing movement of the beam of light in patterns such as linear or circular on the motion that is needed to follow the joint.
Laser Welding of Plastic Polymers
It is a process used to join polymeric compounds using laser technology. Laser welding offers flexible and reliable solutions. It is a non-contact process and provide accurate outcomes and can finely weld polymers. As it is a contactless process, it produces lower heat affected zone. Various lasers are used in the welding of polymers such as Diode lasers, CO2 lasers, and fiber lasers. Polymer laser welding is useful in industries such as automotive and medical etc.
Laser welding techniques used for joining plastics are through transmission laser welding (TTLW), Direct laser welding, Intermediate film welding, and Laser surface heating.
Laser Welding of Cu with Cu
Laser Welding of Cu with Al
Laser Welding of Similar & Dissimilar Materials
Laser welding provides flexible and reliable results in its process. A fruitful method is used for joining two similar or dissimilar pieces of metals.
When laser welding is done for similar metals, a true metallurgical bond is created at the weld seam. Mechanical characteristics of similar materials are better than dissimilar ones due to the sound bonding of similar materials.
Joining dissimilar materials is not easy, it needs a technical and modish processes, laser welding which is a prominent technology is helping with its latest features in many industries such as automotive, aerospace, automobile, etc.
During dissimilar metals welding, the optimal thing is high welding speed. Due to high welding speed, it reduces the interaction time of the metals that have different properties such as melting point, thermal conductivity, etc.
LBW technique removes the burden of using a third type of metal for joining purpose.
Pulsed Beam Laser Welding
It is a technique that is used for thin-section welds, and it is exemplary for spot welding. Pulsed lasers can create high peak powers. A precise weld is created using the welding process and the heat affected zone is lower in this process. It is used in various industries such as medical, electronics etc.
Scanner Welding
Scanner Welding offers exemplary results in its process. The laser beam of light is guided by mobile mirrors. By changing the angle of the mirrors the beam of light can be guided causing the emergence of the processing field. This provides accurate and superior welding. This welding process enhances production efficiency.
Single and Multi-Mode Beam Welding
Single mode lasers are mainly small. Single mode and multi-mode, both are utilized in the field of welding. When penetration welding is needed for thick plates, a single mode is beneficial. Single mode beam is appropriate for welding particularly highly reflective materials.
Multi-mode beam is useful when deep penetration is not needed. It is acceptable for butt and fillet joints. It is utilized when welding work is in the macro range.
Welding Modes
Welding heat modes are created by different power densities. Heating modes that are used to explain the resulting melting during the laser welding process are as follows:
Conduction Mode
In the conduction mode, there is a good power density and here the weld penetration is attained by the conduction mode of heating. Here the welds are generally wider.
Keyhole Mode
In this mode, the weld can be finished at high speeds with deep or shallow welds. In this, the power density is large that not results in melting, but it also vaporizes the material. This type of welding process is useful in automotive components.
Laser Welding of Different Joint Geometries
The way the heat is transferred by the laser welding process is unique and different. This process offers tremendous flexibility regarding welding joints.
Welding Joint Types or joint geometries are as follows:
Butt
It is a joint when two parts are placed together, or we can say two parts of metals are in the same plane.
Lap
This joint is created when two parts are placed on top of each other or in overlapping pattern.
Fillet
It is a joint that is formed when two parts are at an angle or intersect at a 90-degree angle. This joint is also known as Tee joint.
