Metal fabrication is a combination of various prepared metal components, joined together by several methods including welding and securing by bolts and brackets.
Essex Precision Ltd will build your frames and bracket designs to supplied engineering CAD drawings. A variety of welding and fabrication process are being used to manufacture weldments and frames.
These process includes cutting, forming, machining, bending, overlapping, welding and bolting, In many instances products that were machined or CNC’s will be attached to welded frames on a per order custom basis.
The common materials used in welding to fabricate frames and brackets, is plate metal carbon steels of varying thicknesses. These are cut into different links using a press, or a torch where necessary, and further sectioned as needed. Tube stock, or expanded metal forms are very common components of any welded frame. These can be circular, square or rectangular shaped and the requirements of the job will dictate which type is to be used.
Fabrication, Welding and Machining
With this kind of welding, machining and forming, railings of all kinds can be manufactured. Industrial steps can be made to specs and upper railings can be made to provide access to industrial operations. Checker plates, aluminium sheets, tubing, cast iron, tool steel and mesh are used. These are sheared, rolled, formed, and bended or drilled were appropriate. Depending on application, these manufactured welded frames can be powder coated, primed, painted, galvanized, sand blasted, or electroplated (these finishing services are not provided).
Our clients range from large factories within the construction industry, to automation system manufacturing, tool and die fixtures, agricultural operations, diesel and renewable energy generation, OEM and aftermarket automotive industries, environmental companies and commercial establishments.
Welding processes includes MIG welding (Metal Inert Gas), TIG welding (Tungsten Inert Gas), Stick welders and the spot welder for tacking metal components together in preparation for full welding. Depending on the application welding can be one or a combination of several formats.
Cutting: metal sheets and tuning are cut into several sections by a press, torch, band saw or oxy fuel torches.
Bending: The bending of items is completed by press brakes, or stamping.
Burning: Burning is the use of a high temperature flame to cut sections or apertures. These can be laser cutting, plasma torches or water jet cutters.
Forming: In some instances depending on application a metal component will need to be “formed.” This is the controlled application of force to bend a piece of raw material. For example, a piece of metal tubing may need to be rolled into a circular shape.
Machining: A basic welded frame is rarely just needed. In many instances a machined part will need to be attached, or, the item itself will need to be machined, or tapped.
Final Assembly: After the burning, cutting, bending, and machining, it’s now time to combine all the various parts. This is where the tack weld is done to form the final assembly, and then a final complete weld brings all the pieces together.
