The laser is useful for the assembly and cutting of parts and materials. It is a very efficient and modern industrial tool. It is used to weld materials such as metals or plastics. In order to fuse two or more materials, laser welding requires a thermal source: infrared rays.


Many industries can benefit from the use of lasers, especially in the aerospace, automotive and energy sectors. Laser manufacturing allows for the creation of very precise structures, regardless of the material used, whether it is metal, aluminum, steel, or even plastic. These structures can be very diverse depending on the industry. For example, in the automotive industry, the most common structures to be manufactured by laser are engines or bodies. For handcrafted creations, the laser can design and define the shape of a vase by cutting it. The laser can also be used to decorate and assemble plates on this vase, through welding. In summary, there are three applications of a laser in industries such as laser cutting, laser marking and laser welding. Laser cutting is the best known of all, it is used to cut thin materials with a diameter of 30 microns to 30 mm. For example stainless steel, aluminum, ceramics … Its advantages compared to the other two is its simplicity and its high precision. Concerning laser marking, very used in the aeronautical and medical industries, it consists in creating logos, labels, serial numbers for pharmaceutical objects and bar codes. Do not confuse engraving and marking, because the latter is superficial while the other digs, melts and vaporizes the material. Laser welding is the least known, there are two methods of welding such as spot welding and welding with a bead. In order to obtain high quality results, it is necessary to call upon the expertise of an expert. Here is a useful link to the irepa laser website:


The laser industry expert can take charge of projects by drawing up a preliminary estimate of expenses. Laser manufacturing requires a rigorous quality control of the materials used, but the laser machine must also be checked and controlled. The laser beam used must have the diameter of a hair. This is the reason why the energy released is high. It varies from 105 W/cm2 to 106 W/cm2. To guarantee safety and to minimize the working time, the laser industry uses robots. An expert in the laser industry ensures not only a high quality of production but also a large quantity of finished products, thanks to the number of laser machines available.  The services offered by an expert are diversified: feasibility studies, process development, part design, tooling design, optimization / robustness.

For people who already own a laser machine and want to use it themselves, taking appropriate training is imperative. Indeed, to follow trainings makes it possible to know how to use its laser machine well and how to maintain it. Here are the main services on this subject: technical assistance, laser safety audit, metallographic expertise, investment assistance.


The laser industry expert is most often a company and not an individual. In order for this company to use its expertise to satisfy the customers, it is necessary that the customers clearly present their design project, i.e. the appearance of the desired product, as well as its measurements and decorative parts. To take the expert as a manufacturing partner, it is advisable to conclude a written contract at the time of sending the purchase order and set a specific date for the delivery of finished products.
