If you need to repair the metal, welding services may be required. Many different techniques are used depending on the type of job. If you have special needs, check with the company about the most commonly used processes.

Arc welding
There are several different methods of doing this process, but all of them use a power supply that creates an arc that melts the metal at some point. The variations include the following options:
– Shielded metal arc (SMAW). This is one of the most commonly used processes for iron and steel, although it can also be used with aluminum, nickel, and copper alloys.
– Gaseous metal arc (GMAW). It is a premier industrial welding service due to its flexibility, speed, and adaptability to robotic automation. Due to the presence of a gaseous component, it is usually not done outdoors or in areas where the air is volatile.
– Tungsten gas arc (GTAW). This method can be used for most metals but is most commonly used for mild metals and stainless steel. Some of the common uses include bicycles, airplanes, and marine equipment.
– Underwater arc (SAW). During this process, the arc hits the finish that protects the surface from contamination. This top layer also means better working conditions as the rainbow is closed and almost no smoke is formed. It is widely used in industrial applications for large products and pressure vessels.
Gas welding
It is one of the oldest and most flexible welding processes but has rarely been used for industrial applications in recent years. It is mainly used for repair work such as repairing pipes.
The materials needed for this process are usually cheap and easy to use. The process involves acetylene and oxygen to create a flame. The flame is not concentrated as an arc, so the material can cool more slowly.
