Welding of Metal Parts

What types of metal welding do we perform?

Welding is a fundamental technique in the manufacturing of metal components, enabling the precise assembly of a wide variety of sheet metal, tube, and profile parts. Through the controlled application of heat (and occasionally pressure), we melt a portion of the parts or add filler material. Upon cooling, the result is a new metal structure characterized by exceptional strength and ductility.

Broadly speaking, industrial welding is divided into two main groups: systems with wire feed and those with shielded electrodes. At JOM, we master the most common and efficient techniques in the industry, highlighting:

• TIG Welding (Tungsten Inert Gas): As its name indicates, it uses an alloyed tungsten electrode. Thanks to the high melting point of tungsten, this technique is extremely precise, offering superior aesthetic qualities, although its cost is somewhat higher. TIG welding with filler material ensures maximum joint strength.
  
• MIG Welding (Metal Inert Gas) and wire feed: This technique uses an inert gas and a metal electrode that acts as filler material. For this, a gun is used to feed the wire toward the welding area (either via standard guns, where the wire travels from the machine through a cable, or spool guns). It is a faster, more economical technique that provides higher mechanical strength.
  

For large-series manufacturing, manual welding has given way to automation. Our robotic welding stations offer unmatched productivity and high-precision assembly flexibility.

The welding type is carefully selected based on the characteristics of the parts and each client’s specifications, to whom we offer expert advisory services from our technical engineering department.

Finally, our comprehensive service includes various types of finishing for welded parts, such as grinding, sanding, or specific cleaning processes for stainless steel.

Machinery for metal component welding

At JOM, we feature an advanced machinery park that allows us to perform both manual welding (TIG and MIG) as well as spot welding and high-precision robotic welding:

• SUNNARC spot welding machine: This machine carries out a type of welding classified as non-fusion welding of the base metal; additionally, no filler material is required to join the two parts. It is considered a fast, clean, and strong welding method.
  
• Manual MIG/MAG (wire) welding units: Operated by our team of specialized professionals, ideal for small runs of metal parts.
  
• Manual TIG welding units: Our experts master this technique, perfect for the production of small series, prototypes, and pre-series.
  

Our 360º service includes comprehensive advice from our engineering team in design and construction to ensure that the components adapt perfectly to your needs.

Mechanical Welding for Metal Assemblies

Mechanical welding or welded fabrication is a set of manufacturing methods designed for assembling multiple metal components. The choice of the optimal process depends on the nature, shape, and thickness of the materials involved.

To ensure the correct industrialization of components joined by mechanical welding, at JOM we execute a comprehensive process:

• Pre-production phase (product design): We determine the most suitable solutions, evaluating viability, implementation time, and investment costs for manufacturing the welded assembly. This preliminary assessment is carried out in close collaboration with the client and extends through to the installation of production tooling.
  
• Prototypes and pre-series: We validate the suitability of the design and production tools to ensure the final functionality of each part.
  

We guarantee total control over all phases required for the manufacturing of metal assemblies: laser cutting, bending, insertion of fasteners, welded fabrication, finishing, and final assembly.

General considerations on industrial welding

For JOM, ensuring optimal space conditions for all our processes is a priority. In the case of industrial welding, although it can be performed in various environments depending on the client’s needs, we prefer spacious, well-lit areas. Given that this technique involves certain risks, we enforce rigorous safety measures to prevent accidents, electrical shocks, or overexposure to ultraviolet light.
