Industrial <a href=\"https:\/\/double-coeur.fr\/en\/laser-welding\/\"><strong>industrial laser welding<\/strong><\/a> is no trivial matter: it&#8217;s a high-energy density process which, if poorly controlled, can generate deformations and compromise the quality of the assembly. DOUBLE C\u0152UR, a spin-off from IREPA LASER, has been mastering this process for over 40 years.  <\/p>\n\n<h2 class=\"wp-block-heading\"><strong>Precision, low heat-affected zone, reduced distortion<\/strong><\/h2>\n\n<p>Laser welding is a non-contact, localized process. As IREPA LASER explains, it offers precision, fineness of the welded joint, reduced deformation and control of the melted zone. On complex parts requiring flawless assembly, these properties are decisive: targeted melting guarantees controlled penetration and a reduced heat-affected zone, where conventional processes generate more diffuse heat.  <\/p>\n\n<p><strong>Laser welding on machined parts<\/strong> also benefits from instant solidification, ensuring metallic and metallurgical continuity &#8211; an essential point for technical parts requiring robust, repeatable assembly. IREPA LASER also points out that this process reduces or even eliminates the time needed to straighten welded parts, which means direct savings in production times and costs. <\/p>\n\n<h2 class=\"wp-block-heading\"><strong>What we deal with: geometries, materials, configurations<\/strong><\/h2>\n\n<p>Our process engineers analyze each configuration before defining the welding parameters. Wall thickness, joint type, type of material and expected tolerances after assembly are all variables that directly drive beam power, speed and focus settings. This fine-tuning phase is not a formality: it determines the quality of the result throughout the entire production run.  <\/p>\n\n<p>We work on aluminum and its alloys &#8211; a material particularly sensitive to thermal deformation &#8211; stainless steels, titanium, copper and superalloys. Our multi-axis robotized cells handle parts from a few millimeters to several meters, including complex geometries with difficult access. The power of our lasers, up to <strong>10 kW<\/strong>, enables us to adapt welding speed to productivity requirements without sacrificing thermal control.  <\/p>\n\n<h2 class=\"wp-block-heading\"><strong>From unit assembly to repeatable production runs<\/strong><\/h2>\n\n<p>DOUBLE C\u0152UR is involved in all phases of your production cycle. For <strong>machined parts in unit assembly or prototyping<\/strong>, we validate the process, check assembly conformity and deliver parts ready for integration. For repeatable production runs, validated process parameters are recorded and identically reproduced on each batch, guaranteeing consistent results over time.  <\/p>\n\n<p>This ability to go from prototype to series production without any break in methods is one of the advantages that subcontracting manufacturers particularly appreciate: a single contact, a single set-up, reliable production over the long term.<\/p>\n\n<h2 class=\"wp-block-heading\"><strong>Quality, traceability and compliance for your end customers<\/strong><\/h2>\n\n<p>Your end customers have documentation requirements that you pass on to them. DOUBLE C\u0152UR is <strong>ISO 9001:2015<\/strong> certified, and ensures full traceability of every welding operation: recorded parameters, dimensional checks during production, non-destructive testing to your specifications, compliance report on delivery if required. For parts destined for regulated sectors &#8211; automotive, aeronautics, energy, defense &#8211; this rigorous documentation is not an option. We integrate it as soon as we receive your specifications, not at the end of the chain.   <\/p>\n\n<h2 class=\"wp-block-heading\"><strong>Why machinists work with DOUBLE C\u0152UR<\/strong><\/h2>\n\n<p>A manufacturer outsourcing the laser assembly of its parts needs a subcontractor who understands its technical requirements and the nature of the materials processed. DOUBLE C\u0152UR is structured to do just that. Our engineers analyze your configuration, parameterize the process according to your geometry and material, and ensure precise, reproducible assembly in line with your specifications.  <\/p>\n\n<p>A dozen specialized engineers and technicians, more than twenty industrial lasers on site, and an organization capable of handling urgent batches as well as regular production runs: this is the infrastructure that DOUBLE C\u0152UR offers to <strong>machined part laser welding subcontractors<\/strong> who need a reliable partner for the long term.<\/p>\n\n<p>Do you have machined parts to be assembled by laser welding? Send us your drawings or specifications. Our engineers will analyze your configuration and get back to you within 48 hours with initial technical feedback and a cost estimate.  <\/p>\n\n<p>Contact us via <a href=\"https:\/\/double-coeur.fr\/en\/contact\/\">our contact form<\/a> or call our team on +33 (0)3 88 65 54 00.<\/p>\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Entrusting the assembly of your machined parts to a machined parts laser welding subcontractor gives you access to a level of expertise and flexibility difficult to achieve in-house.
