Welding, often considered a metallurgical art, is an ancient technique that has evolved over time to become an essential aspect of modern manufacturing and construction. Depending on the materials and the work to be carried out, metal engineers and craftsmen recommend various types of welding to create strong, durable metal connections. What are the different types of weld? We put the question to Diego Bosmans…
Arc welding, the oldest form of welding
Electric arc welding, also known as coated electrode welding, is one of the oldest and most widespread welding methods. It involves the use of a metal rod coated with a powdered material that creates a protective gas when heated. This technique is often used on construction sites for its versatility and ability to work with a variety of metals.
MIG welding, quick and easy
MIG (Metal Inert Gas) or MAG (Metal Active Gas) welding uses a continuous wire electrode fed by a coil. An inert or active gas is also used to protect the weld from atmospheric contaminants. This method is appreciated for its speed and ease of use, particularly in the mass production of metal assemblies.
TIG welding for greater precision
TIG (Tungsten Inert Gas) welding uses a non-consumable tungsten electrode to create an electric arc. An inert gas is used to protect the weld, offering greater precision and control. This method is commonly used in applications requiring high-quality welding, such as aerospace and electronics manufacturing.
Resistance welding, the preferred choice of the automotive industry
Resistance welding uses the heat generated by the passage of an electric current through the joint area to create the necessary fusion. This method is often used in automotive production to assemble sheet metal parts. It offers high speed and energy efficiency.
Spot welding to avoid sheet metal deformation
Spot welding is a variant of resistance welding, in which welding spots are formed at specific points. This method is widely used in the manufacture of automotive parts and electronic devices. Spot welding is widely used to join metal sheets together, as the brevity of the operation and the precise location of the weld point between the pressurized electrodes limit deformation of the sheets during welding.
Ultrasonic welding, welding for plastics
Ultrasonic welding uses ultrasonic vibrations to melt metals and create a strong bond. This technique is often used in the assembly of plastic and metal parts, offering fast, precise welding.
