#2 - TIG and MIG welding: differences, advantages and applications in the metalworking industry

The image shows a robotic arm performing an automated welding process, a reflection of the precision and technology that characterize the services of CORVATS ESPECIALS SL (COES) in Terrassa (Barcelona). This combination of experience and automation defines the standard of quality in industrial welding processes.

Welding is an essential process in the metallurgical sector. At COES, specialization in TIG and MIG welding allows us to offer precise and resistant solutions for pipe bending and shaping, guaranteeing long-lasting results adapted to the needs of each customer.

Differences between TIG and MIG welding

Both processes share the purpose of joining metals by fusion, but differ in their technique and applications.

TIG welding (Tungsten Inert Gas)

TIG welding uses a non-consumable tungsten electrode and an inert gas, usually argon, to protect the work area. This method offers high precision and a clean finish, ideal for fine work and materials such as stainless steel or aluminum.

MIG Welding (Metal Inert Gas)

MIG welding uses a continuous wire as consumable electrode and a shielding gas. It is a faster and more automated process, suitable for large production volumes and thicker metal structures.

Advantages of TIG welding

• High quality joints.
• Excellent surface finish without the need for retouching.
• Ideal for delicate or thin materials.
• Greater process control and arc stability.

At COES, TIG welding is applied especially in sectors where aesthetics and precision are essential, such as metal furniture, automotive or industrial equipment manufacturing.

Advantages of MIG welding

• Increased speed of execution.
• Possibility of automation, reducing costs.
• Adaptability to different types of metals.
• High productivity in continuous manufacturing lines.

This technique is widely used by COES in structural welding jobs, large parts and projects that require repeatability and efficiency.

Industrial applications of TIG and MIG welding

In the tube bending and forming industry, TIG and MIG techniques are essential to guarantee the structural integrity of each component. COES combines both methodologies depending on the type of material, thickness and customer requirements.

• Stainless steel pipe joints for pipelines.
• Metallic structures for industrial machinery.
• Precision bent components for the automotive industry.
• Manufacture of customized metallic elements.
