Laser welding is typically a welding technique that is used for joining a number of pieces of 
metal by using a laser beam. This laser welding technique offers a concentrated source of 
heat that allows for deep, narrow welds, as well as high welding rates. This process is 
widely used in high volumes of welding applications like in the automobile industry. 
In the automotive industry, laser welding is applied in ways that allow manufacturers to 
weld component engine parts, alternators, fuel injectors, transmission parts, and air and 
conditioning equipment, to name a few. It is an excellent tool for its ability to weld pre-
machined elements with minimal deformity and restricted heat.

Main Applications of Laser Welding In the Automotive 
Industry
In the automotive market, we have been witnessing a significant increase when we talk about using laser 
welding in the manufacturing process. In fact, it has become common for a lot of automotive 
applications, such as the welding of door frames, body frames, auto hoods, trunks, and chassis, as well as 
plastic welding for back and front lights.
Another prominent trend favors laser welding is the extensive increase in electronics within automobiles 
compared to the past. Nowadays, almost everything is managed by a computer, and the only thing you 
can do by hand is to refill the windshield wiper fluid.
It is widely used for wielding many metal sub-components such as motor coil windings, airbag initiators, 
electrical interconnection within the vehicle, and battery tab-to-bus bar connections.

Impact On Laser Welding For The Automobile Industry
To date, the most prominent trend is electrifying automobiles, as we can see by so many hybrids as well as 
all-electric vehicles launching in the market. They need welding for electrifying motor components such as 
stator hairpins and powertrain connections. 
Additional essential applications in electrifying vehicles are battery welding and connections. The industry 
needs welding in order to develop the battery cell, joining cells to design a module and connecting the 
modules to make the whole battery assembly. 
All the connections in the battery pack and electric motor are usually of conductive materials, and the best-
suited option for them is laser welding. Welding joints also require high strength which implies that welds 
need to meet this criterion.
The technology of laser welding is also perfectly suited for high-speed production lines, especially fibre 
lasers that do not have any power degradation and consumables.
