Welding is a process used to permanently join two or more pieces of metal, a form of fabrication. It is one of the most commonly used techniques in construction and manufacturing. Stick welding, also known as shielded metal arc welding (SMAW), is one of the oldest and most economical form of welding in existence.
Stick welding is used in multiple industries because of its simplicity, portability and low cost. With more than
2 million people employed in the welding industry worldwide, its importance in the modern world is hard to overstate. Stick welding has been used to manufacture everything from solar panels to missiles and aircraft.
It can be used to weld both thick and thin metal in a variety of temperatures and applications. In this article, we’ll take a closer look at what stick welding is, how it works and why it is an important process for industrial applications.
What Is Stick Welding?
Stick welding, also known as Shielded Metal Arc Welding (SMAW), is one of the oldest and most widely used welding processes. It uses an electric current to create an arc between an electrode and the workpiece, enabling the weld and parent material to join together.This technique is often used for outdoor welding or for welding on dirty or rusty materials, as it is less susceptible to environment contamination than other processes.
Advantages of Stick Welding
Stick welding offers many advantages and is the preferred choice of many experienced welders for welding in jobsites.These advantages include:
- Low cost – the welding machines and electrodes used for stick welding can be relatively inexpensive, making this process economical.
- Robust – the durable stick welding machines are often portable and made of highly-durable materials, making them ideal for outdoor welding.
- Versatile – the process works to join many metal types, including steel, stainless steel, aluminum, and cast iron.
- Less susceptible to contamination – stick welding is less affected by dirty or rusty metals than other processes.
- Easy to learn – generally, stick welding is easy to learn and can be mastered quickly.
Disadvantages of Stick Welding
While stick welding offers many advantages, it also has some drawbacks.- Low weld speeds – stick welding is slower than other processes, with low weld speeds.
- Higher power requirements – stick welding requires more power than other processes, and thus higher-powered welding machines.
- Spatter – stick welding often produces high amounts of spatter, requiring additional cleaning of the welded area.
- Flux burn off – the flux used to protect the weld from contamination can burn off quickly, requiring frequent electrode changes.
- Overshoot – stick welding often produces too much heat, which can result in an overshoot on the weld.
Conclusion
Stick welding is a popular and versatile process that is widely used in outdoor welding jobsites. It offers many advantages, such as low cost, robustness, and versatility, while also having some drawbacks, such as low weld speeds, high power requirements, and spatter. Ultimately, stick welding may be ideal for welders wanting to join many metal types and welding in a dirty or rusty environment.
