Industrial Welding

At EMS Group, we specialize in providing high-quality welding services that meet the demands of various industrial applications. Our commitment to excellence and innovation in all our processes ensures strong and durable joints, guaranteeing the integrity and functionality of each project.

Our team of experts includes including professional welders and IWS (International Welding Specialist). In addition to ISO 9001, we have the UNE EN 1090 standard, guaranteeing that our welding processes are carried out under the highest standards of control. We implement rigorous quality control at every step, from surface preparation to final inspection, ensuring that any joint meets the expected strength and durability requirements.

In addition to having professional welders to carry out manual welding processes, we also have industrial robots and cobots in our production lines in which we use equipment with the latest technology, such as CMT (Cold Metal Transfer) welding. This allows us to optimize production times thanks to its higher speed, reduce tensions caused by thermal input and achieve welds that guarantee maximum precision and quality.

Types of Welding

• MIG/MAG welding: At EMS Group, we offer arc welding using MIG/MAG and TIG techniques, which are widely recognized for their versatility and effectiveness. MIG/MAG welding is ideal for joining metals through a molten material addition process, allowing for a high welding speed and is suitable for a variety of materials such as carbon steel and aluminum.

• TIG welding: TIG welding is preferred for applications that require a high degree of control and precision, such as stainless steel and titanium. Both techniques guarantee high-quality joints, with clean finishes and consistent penetration parameters, minimizing deformation and maximizing strength.

• Oxyacetylene Welding: This method combines oxygen and acetylene to produce an intense flame that melts the base metals. Oxyacetylene welding is effective for repairing and joining parts of various thicknesses.

• Submerged Arc Welding: In this process, the welding arc is formed under a granular powder coating that protects the weld from the air, removing contamination and improving the quality of the joint. This method is ideal for high-production welds in controlled environments and is particularly effective in joining thick sheets and heavy structures of large industrial components.

• Stick Welding: Also known as manual arc welding, it uses a coated electrode that, when melted, releases gases that protect the weld from oxidation. This technique is versatile and adapts well to various working conditions, being suitable for welding materials such as carbon steels and some types of alloys. Its ease of use and low cost make it an affordable option for many welding projects.

• Laser Welding: We use state-of-the-art laser welding technology, which stands out for its high precision, speed and ability to weld materials of different thicknesses. This method is especially effective for making delicate joints and on small components that require a superior aesthetic finish. Laser welding also minimizes thermal impact on areas adjacent to the weld, helping to prevent distortion and ensuring material integrity. This makes it a preferred choice in industries such as aerospace, electronics, and design.

• Brazing Welding: Our controlled atmosphere furnace brazing (brazing) service allows the joining of metals through a process that uses a filler material with a lower melting point than the base metals. This method is ideal for applications that require strong and durable joints. Brazing welding provides excellent strength and is used in the automotive industry where joint integrity is critical and cost must be very competitive.

• Bolt Welding: At EMS Group, we have the advanced capacitor discharge welding technology, which allows the welding of bolts, studs and threaded bushings, guaranteeing an optimal and aesthetically appealing finish.

• Resistance Welding: Resistance welding is another key method we use. This process is based on generating heat through the electrical resistance in the parts that are being joined, applying simultaneous pressure. Resistance welding is ideal for applications where fast and strong joints are required, such as in the automotive industry. This method allows for high productivity and excellent repeatability, resulting in consistent, mechanically resistant joints.

Welded Materials

At EMS Group, we have the capability to weld a wide range of materials, including:

• Carbon Steel: Used in various applications due to its good ductility and strength.
• Stainless Steel: Ideal for corrosive environments, it guarantees durability and resistance to oxidation.
• Aluminium: Its low density and good electrical conductivity make aluminum a popular material in modern industry.
• Titanium: Known for its high strength-to-weight ratio and excellent corrosion resistance, titanium is ideal for aerospace and biomedical applications.

Delivery time

We use state-of-the-art welding equipment, industrial robots, cobots, welding tables, positioners,…. which allows us to produce high-precision parts whether they are prototypes, short series or long series in short delivery times.

Custom finishes

At EMS Group we offer a comprehensive welding service that is not only limited to the manufacture of metal parts, but also includes options for custom surface finishes.

In addition to our welding service, we provide the possibility to deliver the product with high quality finishes, such as:

• Liquid Paint: This process involves applying a liquid paint to the surface of the metal part. Liquid paint provides a protective layer that helps prevent corrosion and improves the visual appearance of the product. Different types of paint can be used, including water-based and solvent-based paints, which offer a wide range of colors and finishes.
• Powder Coating: A coating method in which a powder-like paint is applied that is cured in an oven, creating a thick, durable layer. Ideal for outdoor applications, thanks to its resistance to scratches and wear.
• Zinc: Zinc plating is a coating process that involves the application of a thin layer of zinc over the metal surface. This finish provides effective corrosion protection and is commonly used for parts that will be exposed to harsh environmental conditions
• Hot Dip Galvanized: Hot-dip galvanizing involves coating metal parts with zinc. This finish provides long-lasting protection against corrosion and is especially effective in wet or corrosive environments.
• Custom finishes: We can customize your finishes according to your needs.

In addition, for the convenience of our customers, we also offer the complete assembly service of the assembly, allowing a turnkey delivery. This means that you will receive a finished and ready-to-use product, thus simplifying your procurement process and optimizing implementation time.

Trust us to provide complete and quality solutions in each of our services.
