Recovery and deposition welding during the machining process

At Talleres Mecánicos Arri, welding is integrated into machining services with standardised TIG and MIG-MAG welding processes by ASME Section IX. This translates into significant time savings and improved efficiency. It is common for parts to have imperfections or require additional materials on the piece being machined. The ability to perform this work directly on the production line adds value as a supplier, optimising the process and reducing lead times and costs for clients in energy and petrochemicals.

Recovery and Deposition Welding

Arri, Certified to ASME Section IX Standards

In the metalworking industry, welding is a precious service and activity, particularly in sectors that require components capable of withstanding severe conditions, such as high pressures, elevated temperatures, or corrosive environments. At Talleres Mecánicos Arri, TIG and MIG-MAG welding processes, certified under ASME Section IX, complement machining by offering repair and reinforcement solutions by depositing material in critical areas. These processes also enable real-time repairs, optimising production by reducing downtime and helping projects meet deadlines.

The TIG welding process (Tungsten Inert Gas) provides precise finishes on thin materials and difficult-to-weld materials. TIG welding allows Arri to restore specific areas of worn parts while preserving the integrity and mechanical properties of the original material.

The MIG-MAG process (Metal Inert Gas and Metal Active Gas) and the MIG-MAG process are arc welding processes that use a consumable metal electrode (a wire) and a shielding gas. The primary difference between the two lies in the type of gas used. At Arri, MIG-MAG welding is employed to repair defects and deposit materials to reinforce components, enhancing the durability of parts subjected to constant wear.

Recovery of Mechanical Components Through Welding

Component Recovery: With TIG and MIG-MAG welding, Arri can, where possible and with client approval, recover worn or deficient components, ensuring their original properties without replacing the entire part. This reduces costs and downtime for clients.

Component Reinforcement: Deposition welding allows for adding wear-resistant materials in critical areas. This is especially useful for parts exposed to constant friction or high temperatures. Using materials such as Stellite Gr6 and Inconel 625, Arri enhances part resistance and extends its service life.

Adaptation to Complex Materials: Arri's certification includes materials such as martensitic steels and superalloys like Inconel 625. This is essential for sectors requiring specific mechanical properties, such as high resistance to corrosion and wear.

Improvements in Final Product Quality: Arri's welding and machining processes undergo stringent quality control, ensuring that each part meets client requirements.

The Value of Welding Services at Talleres Mecánicos Arri

Incorporating welding services into machining is a clear competitive advantage for Arri’s clients. With ASME certification, Arri ensures the quality and safety of each weld, meeting the rigorous standards of client orders in sectors like energy and petrochemicals.

Additionally, welding complements machining, enabling Arri to add value by recovering or adding material in certain areas, resulting in parts with mechanical characteristics that meet client specifications.

With this certification, Talleres Mecánicos Arri advances its commitment to quality in the recovery welding process under ASME Section IX, ensuring TIG and MIG-MAG welding on carbon steel, stainless steel, Stellite Gr6, and Inconel 625 on steel bases. Thanks to this certification, Arri offers a reliable and high-precision solution for the demands of critical and specialised sectors.
