Metalwork comprises many of the practical and aesthetically pleasing items we enjoy today. From the tiniest fasteners to tools, to skyscrapers and sculptures, metalwork plays an active role in our daily lives. Metal fabrication helps keep manufacturing functioning, our industries pumping out the goods we use every day. In this system, metal fabrication welding actively contributes.
Welding: Functions and Methods
Welding is the joining of two or more pieces of metal and/or other materials. It requires the understanding of fusion. It demands comprehension of metal or material melting points and composition. It also requires a working knowledge of the various types of welding capable of achieving this goal.
Successful welding fabrication is attainable through one of several methods. Fabrication companies may utilize older and new technology to provide welders and their customers with the best results possible. The better-known ones are:
- FCAW (Flux-Cored Arc Welding)
- Gas Metal Arc Welding (GMAW) or MIG (Metal Inert Gas) Welding – using either bare wire or flux core. This is the most common type of welding in use
- Plasma arc welding
- Tungsten Inert Gas (TIG) or GTAW (Gas Tungsten Arc Welding) welding
- Shielded Metal Arc Welding or SMAW
- Stick Welding (aka Arc welding) SMAW is a variation
Brazing and spot welding are two other methods of producing welds. While many of the basic techniques remain the same, technology continues to improve the rudimentary equipment, making it faster, more accurate, easier to handle and control and safer. The latest advances are improving ventilation and reducing instances of the harmful effects of flash. Some companies are working hard to reduce such things as awkward postures and extreme noise exposure commonplace to this occupation.
Welding is an old craft, skill, and trade. It is also an art. Welders work efficiently and with a dedication to providing components for a great many industrial sectors. From agricultural to fashion to tools to walkways, welding fabrication produces items capable of enriching all our lives.
