Manufacturing metals can be a complex process, and there are many different tasks to be completed to produce quality parts. One process with a major impact on final quality is welding, a process used extensively in producing industrial shelving units. Put simply, welding is the process of attaching pieces of metal to each other and is a very skill intensive trade. It is important to get a welding job done right as it could impact the final strength of the industrial shelving units.
Welding usually uses a filler metal which is passed into the join to attach two metals or thermoplastic pieces. Heat or pressure is used to complete the join. Some of the main welding methods used in sheet metal manufacturing include:
- Stick Welding – the process uses a handheld electrode to make an extremely hot arc at the tip, which melts the metals, allowing them to join. It is the cheapest form of welding and it is quite portable, capable of being performed outside and in tight spaces. However, it is a slow process, inefficient, and cannot produce some precise joins in industrial shelving units.
- MIG Welding – involves a filler metal being fed through a wand to the join while surrounded with an inert gas. This prevents any external reactions from outside elements. It is easily learned and once mastered can produce incredibly smooth and clean welds which are vital for visible surfaces in sheet metal manufacturing.
- TIG Welding – this is one of the rare methods of welding which does not need a filler metal to complete. The method uses a tungsten electrode and a constant stream of gas to protect the weld from outside reactions. It can produce very clean welds with almost zero cleanups required and the welds are typically much more appealing for visible surfaces such as the faces of industrial shelving units. It requires a lot of skill to perform.
