As a heat treatment specialist, we are often asked about the various standards and codes there are in the field of welding. Given that we provide furnaces and kilns for sensitive sectors like the aerospace industry, sanitaryware manufacturers and solar energy businesses –among others – welding quality is a question that crops up again and again. This is why we are proud to have been certified under the demanding BS.EN.ISO 9606-1 standards for welding quality
The Advantage of BS.EN.ISO 9606-1 standard
All these welding methods can be employed in our work, but the most relevant technique is fusion welding, which is the area of competence covered by BS.EN.ISO 9606-1. This is a harmonised standard, meaning it complies with standards expected under BS, ISO and CEN rules. In other words, a kiln fusion welded under BS.EN.ISO 9606-1 criteria can safely be used anywhere in the world.
It takes high-quality workmanship to be able to weld to the rigorous standards of any ISO accreditation, including 9606-1. Any customers who want to know their welding processes – whether they are arc welds, laser welds, induction welds, oxyfuel or solid reactant welds – are being carried out by a fully accredited contractor should seek out a BS.EN.ISO 9606-1 compliant manufacturer.
The heavy fabrication process involves a number of different steps, including design, material selection, cutting, welding, bending, and finishing. Each of these steps requires specialized equipment and skilled technicians to ensure that the final product meets the necessary specifications and quality standards.
One of the key advantages of heavy fabrication is its ability to produce structures that are both strong and durable. Because these structures are often exposed to extreme conditions, such as high winds, heavy rain, and corrosive materials, it is essential that they are able to withstand these forces and remain intact over time. Heavy fabrication techniques and materials are specifically designed to provide this level of strength and durability, making them an essential part of many construction and manufacturing projects.
Another benefit of heavy fabrication is its versatility. With the use of computer-aided design (CAD) and advanced machinery, it is possible to create a wide variety of shapes and sizes, allowing for the creation of complex structures that would be difficult or impossible to produce using traditional methods. This versatility makes heavy fabrication ideal for a range of applications, from building bridges and offshore platforms to manufacturing large industrial equipment and machinery.
Fabrication Processes We can Offer
Welding: Welding is a process of joining two or more pieces of metal together using heat and/or pressure. The heat can be generated by a flame, an electric arc, or a laser. Welding can be used to create structures, repair damaged components, or add additional material to existing components. There are several types of welding processes, including MIG (metal inert gas) welding, TIG (tungsten inert gas) welding, stick welding, and gas welding.
Extrusion: Extrusion is a process of forcing a material through a die to create a long, continuous shape with a constant cross section. The material can be metal, plastic, or rubber. Extrusion can be used to create products such as tubing, rods, and profiles.
Sheet metal fabrication: Sheet metal fabrication is a process of cutting, bending, and forming thin sheets of metal to create various products. Sheet metal can be cut using laser cutting, waterjet cutting, or shearing. Bending can be done using press brakes or roll forming. Forming can be done using punching or stamping.
3D printing: 3D printing is a process of creating objects by layering material using a 3D printer. The printer reads a digital file and creates the object by depositing material layer by layer. 3D printing can be used to create complex geometries, prototypes, and custom parts.
MIG welding (Metal Inert Gas): MIG welding is easy to learn, versatile, and can be used on a wide range of metals, including aluminum and stainless steel. It produces high-quality welds with good penetration and minimal spatter, making it a popular choice for both DIY and professional welding projects.
TIG welding (Tungsten Inert Gas): TIG welding produces extremely high-quality welds with precise control over the heat input and weld puddle. It can be used on a wide range of materials and thicknesses and is often used for precision welding of delicate or complex parts.
Stick welding (Shielded Metal Arc Welding): Stick welding is a versatile and inexpensive welding method that can be used on a wide range of materials and in outdoor or windy conditions. It is often used in construction, maintenance, and repair projects.
Flux-cored welding: Flux-cored welding uses a continuously fed wire electrode that contains a flux core, eliminating the need for a separate shielding gas. It is often used for welding thick or dirty materials and is a popular choice for outdoor and field welding applications.
Gas welding: Gas welding uses a flame to heat and melt the metal, which is then joined using a filler rod. It is a versatile welding method that can be used on a wide range of materials, but it requires a high degree of skill and experience to produce high-quality welds.
