Find the Welding Service for Your Specific Needs

A welding service may be needed if you have any kind of metal to repair. There are many different techniques that are used, depending on the type of job. If you have a particular need, ask the company Welding service Gosford about the processes they use most often.

Arc Welding

There are different methods of performing this process, but they all use a power supply that generates an electrical arc that will melt the metal at a specific point. Variations include the following options:

Shielded metal arc (SMAW). This is one of the most commonly used processes for iron and steel, though it can also be used with aluminum, nickel and copper alloys. It was historically used for constructing steel structures and in industrial fabrication, but today, it has become the primary method used in the maintenance and repair fields.

Gas metal arc (GMAW). This is the primary industrial welding service because of its flexibility, speed, and adaptability to robotic automation. Because of the gas component, it is usually not performed outside or in areas where the air is volatile.

Gas tungsten arc (GTAW). This method can be used on virtually all types of metals, but it is most commonly used on light metals as well as stainless steel. Some common applications include bicycles, aircraft, and naval equipment.

Submerged arc (SAW). In this process, the arc is struck under the flux covering layer, which protects the surface from contaminants. This finish also means better working conditions, as the arc is closed and almost no smoke is generated. It is usually used in industrial applications for large products.

Gas Welding

It is one of the oldest and most flexible welding processes, but in recent years it is used less and less for industrial applications. It is usually used for repair work, such as repairing pipes and tubes. The materials required for this process are generally inexpensive and easy to use. The process involves acetylene and oxygen to produce a flame. The flame is not as concentrated as an electric arc, so the material can cool more slowly.

Resistance Welding

This method produces heat by sending currents through the resistance caused by the contact between two or more metal surfaces. The metal melts into small pools at the targeted area. While this method is efficient, there are not many useful applications. The equipment for this method can also be costly.

Energy Beam Welding

Energy beam methods are becoming more popular. This process has very high energy density, resulting in deep penetration and a smaller weld area. It is a very fast, efficient method, and it is easily automated. There are two types of energy beams: laser and electron. The main difference between the two types is the source of power. The laser beam process uses a highly focused laser beam, while the electron method is done in a vacuum using an electron beam.

Consider the different welding services available for your specific need. Talk with a company that has experience for your particular application so that you will have the results you expect.
