Manufacturing welded metal structures
Actual Throat: The shortest distance between the weld root and the face of a fillet weld. Molten metal is forced away from the cut by a blast of forced air. Alternating Current AC : An electrical current that reverses its direction at regular intervals, such as 60 cycles alternating current AC , or 60 hertz. Amperage: The measurement of the amount of electricity flowing past a given point in a conductor per second. Current is another name for amperage. Arc: The physical gap between the end of the electrode and the base metal.VIDEO ON THE TOPIC: Welding Fabrication - Welding The Frame Down

Welded metal structures currently play a key role in the Finnish economy and especially in the export industry, laying a foundation for the future prosperity of the Finnish society. By choosing welded metal structures you will acquire the skills required for tasks in the concurrent engineering of design and the fabrication of innovative welded structures for demanding applications. You can specialise in design, welding technology or laser technology. In addition to profound theoretical knowledge, you will acquire expertise in modern design methods and analysing tools, such as fatigue design and FEA, or modern structural materials and manufacturing processes, such as smart adaptive robotic welding and laser based production. This wide field of demanding applications will undoubtedly need new experts in Finland, but it will also open doors for you globally.
Most of the structures produced by us are delivered for further processing or sale in a coated condition, which operation is performed in our modern paint shop opened in Our features:. Our CNC-controlled bending machines are capable of the high-precision bending of aluminium, stainless steel and steel, up to 5 mm thickness in case of sheets of 3 metres. Representing a significant portion of our products are metal structures and partly electronically fitted air conditioning enclosures, electrical switchgear cabinets for industrial applications, custom-made sheet metal parts and cable ducts.
What is metal fabrication and where is the industry headed?
In addition, they manufacture structural metal and metal plate products. These companies are known for fabricating iron and steel for structural purposes and metal sections. Examples include bridges and buildings, ships, boats, and barges. To help visualize what this industry entails, take a look at these images:. The Structural Metal industry employs a little over , employees. The ironworker is the occupation known for making metal structures appear before us. These workers use shear, rod-bending machines and welding equipment to cut, bend, and weld. Based on these stats, Welding safety gear is essential for protecting workers from metal spatters, molten metal, UV and radiant heat. A worker stick welding on structural metal. Here is a look at all occupations found across this industry.
What Are the Most Common Metal Fabrication Processes and What Are the Applications?
These are the proceedings of the International Conference on Design, Fabrication and Economy of Metal Structures held on April in Miskolc, Hungary which contain 99 papers covering:. The authors are from 23 different countries, ensuring that the themes covered are of worldwide interest and importance. He teaches design of steel structures, welded structures, composite structures and optimization in Hungarian and in the English language for foreign students. His research interests include structural optimization, mathematical programming techniques and expert systems. Having successfully defended his doctor of technical science thesis D.
We carry out a full range of works on the manufacture, dismantling of old and installation of new metal structures pipelines, supports, cyclones, columns, platforms, railings, overpasses, etc. Dismantling and installation of new equipment. Cooperation with us in this direction means timely and high-quality replacement of your damaged metal structures and the creation of new opportunities for your needs.

A common quality of all those products is the fact that they are made of sheet material and are useful both in construction and agriculture. Profexpert metal structures manufacturing plant specializes in welded structures. Metal structures are made of rolled metal products of various configurations and qualities.
Metal fabrication is the creation of metal structures by cutting, bending and assembling processes. It is a value-added  process involving the creation of machines, parts, and structures from various raw materials. Typically, a fabrication shop bids on a job, usually based on engineering drawings , and if awarded the contract, builds the product. Large fab shops employ a multitude of value-added processes, including welding, cutting, forming and machining. As with other manufacturing processes, both human labor and automation are commonly used.
To give a brief outline of the fabrication process for steel structures; to identify the factors affecting manufacturing costs and to stress the importance of the designer considering the fabrication process when preparing the design. The lecture gives a brief summary of the forms of contract and organisation used for the fabrication of steel structures. It reviews fabrication processes with brief descriptions of the main operations. The objective of this lecture is to give an insight into the fabrication aspects of steel structures. Optimum design of steel structures can only be achieved if fabrication and erection are considered together with the functional, architectural and structural requirements.
During the manufacture of welded units, we always meet the highest standards and regulations. High quality, time flexibility and years of experience ensure maximum customer satisfaction with the final product. Manufacture of Steel Constructions Our company manufactures steel structures weighing up to 6 tons.
Some of our capabilities in heavy metal fabrication services include preparation of metal surfaces, by sawing, burning, bending, beveling, and rolling, fitting and welding the pieces into assemblies, machining the pieces and assemblies according to required tolerance and surface finish, and assembling the manufactured parts into semi-finished or finished equipment. We provide all fabricating services from piping to electrical connections. We also offer shop preparation and painting services to meet your requirements.

Metal fabrication is the process of building machines and structures from raw metal materials. The process includes cutting, burning, welding, machining, forming, and assembly to create the final product. Metal fabrication projects include everything from hand railings to heavy equipment and machinery. Specific subsectors include cutlery and hand tools; architectural and structural metals; hardware manufacturing; spring and wire manufacturing; screw, nut, and bolt manufacturing; and forging and stamping. The main benefit of metal fabrication shops is the centralization of these many processes that are often required to be performed in parallel via a collection of vendors.

Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics , by using high heat to melt the parts together and allowing them to cool causing fusion. Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering , which do not melt the base metal. In addition to melting the base metal, a filler material is typically added to the joint to form a pool of molten material the weld pool that cools to form a joint that, based on weld configuration butt, full penetration, fillet, etc. Pressure may also be used in conjunction with heat, or by itself, to produce a weld. Welding also requires a form of shield to protect the filler metals or melted metals from being contaminated or oxidized. Many different energy sources can be used for welding, including a gas flame chemical , an electric arc electrical , a laser , an electron beam , friction , and ultrasound.
Machines have enabled many seemingly unrealistic ideas and have facilitated a multitude of challenging functions. Machine science is one of the oldest and most traditional of the engineering sciences, characterised by a strong desire to think differently and effect change in the world. The high-level civilisation in the world is based strongly on welded metal structures, which keep constructions in shape and machines running. Their design and production are one of the most fascinating engineering tasks.
