Welding remains crucial in numerous industries. Various techniques are commonly used, one of which is MMA welding. Let’s look at what MMA welding is, where it is used, and what advantages it has over other methods.
What is MMA welding?
MMA, or manual metal arc welding, is a popular welding technique amongst professionals and hobbyists alike. It is a manual process in the sense that the welder has to guide the electrode by hand, and it uses metal as a base material. The technique relies on an electric arc to generate the heat needed to fuse/join metals.
MMA welding applications
There is a vast range of scenarios in which MMA welding can be used. Examples include:
- Shipbuilding: to join larger sections of boat hulls together.
- Furniture manufacturing: to create sturdy and attractive metal furniture.
- Pipelines: the pressure-resistant and watertight welds that MMA provides are crucial for joining sections of pipelines.
- Repairs: equipment and machinery can be repaired using MMA welding.
Tapping machines
Tapping machines are a very efficient way of creating uniform threads, with Roscamat being one of the world’s leading manufacturers of tapping machines. Companies such as https://www.cotswold-machinery-sales.co.uk/roscamat-tapping-machines/ stock a selection of Roscamat tapping machines.
What are the advantages of MMA welding?
Despite the emergence of new methods, such as MIG/MAG and laser welding, MMA has several advantages:
Versatility
MMA is a versatile technique that can be used on a wide range of metals, including stainless steel, mild steel, cast iron, and aluminium. It can also be used on specialist alloys.
Cost-effectiveness and efficiency
The equipment needed for MMA welding is relatively inexpensive compared to that needed for other welding types. It generally offers good value for money. MMA welding is also a very efficient method and is suitable for both large and small projects.
Ease of use and portability
MMA is a relatively simple technique to learn and master. Additionally, most MMA welding machines are compact and fairly lightweight, meaning they can be used in small spaces and on- or off-site.
