When most people think of welding, they picture a scene from a movie where someone ignites and acetylene torch, adjusts it to a fine flame and starts welding two pieces of metal together. It’s not a bad representation but, like most things Hollywood, it’s not entirely accurate either.
There are in fact four common ways to weld and depending on what type of project you’re tackling, one type of welding might be more applicable than another. Take a look at the four base types of welding and how they lend themselves to steel fabrication in Phoenix, AZ:
- Metal inert gas welding (MIG): Far and away the most common type of welding, MIG welding utilizes a direct, high voltage power current in conjunction with a shielding gas to heat two segments of metal to their melting point. The various techniques for MIG welding—globular, spray, pulsed-spray and short-circuiting—can be utilized based on the preference of the welder and the requirements of the application.
- Tungsten inert gas welding (TIG): When non-ferrous materials need to be welded together to a supreme degree of sturdiness, TIG welding is often looked at above all other welds. TIG welding is the most complex form of welding and requires the highest degree of proficiency to accomplish to a degree of mastery, but experienced welders have been known to produce exceptional results when using a tungsten electrode as a welding catalyst.
- Shielded metal arc welding (SMAW): For heavy duty welding that leaves incredible bonds behind, SMAW welding is a staple for steel fabrication in Phoenix, AZ. For this method, a high-voltage electrical current is used to create an arc that’s powerful enough to join high-density metals, including iron and steel. This method is highly versatile and often the path for beginning welders, as it exposes them to the core fundamentals of welding.
- Flux cored arc welding (FCAW): This welding method is an alternative to SMAW and offers quickness and reliability in a weld. As a result, FCAW welding is commonly used in a pinch on construction sites and in industrial settings where simple welds are required. The equipment used in FCAW welding is also highly portable and low profile, making it a smart solution to mobile and on-site projects.
All of these methods of welding have their own unique set of properties, making the use of them a per-project decision that’s often at the discretion of the fabricator. Also, it’s important to remember that proficiency with one form of welding doesn’t make someone a master—each comes with its own set of techniques and understandings that will serve to make for a job well done.
When your need for steel fabrication in Phoenix, AZ involves welding, consult with a fabrication specialist about what method of welding is best suited for the project. Choosing the right weld and have it undertaken by an experienced welder will result in a high degree of quality long after the torch has been turned off.
