Laser welding is a fantastic way to join different metal parts. As usual, the method uses high-power laser beams to melt metals and then uses the molten metal to weld the separate parts. The joining technique may vary based on different material types. Deep penetration laser welding is one of the most popular techniques. And it is mostly used for thicker metals. Another method used is heat conduction welding. This technique can create penetration depths of up to mm and is widely prevalent for welding thinner metals.
Both of these techniques may use pulsed or continuous lasers. Also, they may come with CO2 lasers or fiber lasers. The exact type typically depends on various factors. However, fiber lasers are the most popular here.
Both heat conduction welding and deep penetration welding have unique pros and cons. You can choose the right type for your project by comparing these pros and cons. This way, you can ensure a better and more reliable welding result. The suitability also changes when considering the difference between pulsed and continuous lasers.
The pulsed laser provides an interrupted laser beam, but the continuous laser does not. A pulsed laser is ideal for working with thin metals. This laser source also produces less distortion and HAZ. You will find its use in heat-conductive laser welding. A CW laser is exclusively suitable for thick metal welding. You can not use it on soft or thin metal parts because it will create distortion and a large HAZ.
This type of laser is also used in deep-penetration welding. This article is all about the deep-penetration laser welding method. How does this welding work, and what are its benefits? DPLW laser welding uses a highly focused laser beam, mostly continuous lasers. It penetrates deeply into the material to form a keyhole. A keyhole is a small cavity that extends deep into the workpiece. This keyhole creates a greater weld depth during laser welding than other methods.
