Certified welding

Welding is one of our first services SMI offers since the foundation in 1980 and have extended the amount welding techniques since. SMI Plaatwerk offers a wide range of welding processes to fit the requirements and needs of the final product.

We have experience with the most common welding techniques: MIG, MAG and TIG but when preffered also with arc welding (MMA), gas welding, stud welding, and spot welding. With our extensive quality control and welding procedures, SMI Plaatwerk can guarantee the highest quality welding and certified welding process.

SMI Plaatwerk is direct and indirect active in many different markets. Some of the markets in which SMI Plaatwerk is active are: defence, mechatronics, medical and security. Often, our solutions and application developed for a particular market sector or product can be reused in other market sectors.

ALL TECHNIQUES

At SMI we are certified for the most common welding techniques: MIG welding (process 131), MAG welding (process 135 and 136) and TIG welding (process 141)

TIG uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an shielding gas such as argon or helium. TIG is ideal for welding sheet metal up to 3 mm but can weld a maximum thickness up to 6 mm.

MIG uses a wire feeding gun that feeds wire and flows an argon or helim-based shielding gas over the weld to protect it from contamination. As argo or helium is used as a shielding gas, MIG welding is ideal for aluminium or stainless steel as it prevents corrosion of the material. MAG welding is ideal to weld steal structures and products together. MAG is identical to MIG welding, the only difference is that an active gas is used. That is why in the technical world it is common as MIG/MAG welding. MAG welding is used to weld steal structures and products together. For both process, the welding thickness can be up to 50 mm.

MATERIALS

Because of the wide range of welding processes, SMI Plaatwerk can weld a wide range of sheet metal structures such as: steel, high strength steel, wear resistant steel, stainless steel and aluminum. Depending on the application and purpose of the final product, SMI can give the necessary advice on which materials should be used. For our offshore market, it is common that high strength steel is used as these products have to handle heavy loads and structures.

Welding other materials such as steel requires a high amount of expertise. SMI Plaatwerk in-house expertise makes sure that the quality and properties of the materials such as high strength steel and aluminum are not lost during the welding process.

NORMS & CERTIFICATES

Besides the standard ISO 9001:2015 certificate, SMI Plaatwerk is also ISO 3834-2 certified. This certificate shows that SMI can safely weld high quality structures for specific sectors such as Offshore, petrochemical, heavy duty lifting. During the process executed by qualified welders, a welding coordinator supervises the approved procedures. These certificates apply to the entire welding organization.

SMI is always prepared to obtain certificates to produce your welding work. This is what we do on a regular basis for our customers, for example: for the German defense sector we have obtained the DIN-2303-Q2BK2 Certificate. In The Netherlands, there is only a select group of companies that can carry this certificate. A DIN 2303 certified company is under strict supervision of an accredited independent supervisor to guarantee high quality welding procedures.

HIGH PRECISION

With our certified welding process we can guarantee that for every market a high quality solution is produced. Thanks to SMI Plaatwerk management quality control system, every weld is delivered to the highest standards. That is why many defence suppliers trust SMI sheet metal department with the producten of their equipment or parts.

At SMI Plaatwerk it does not matter what the size of the final product is, all products are delivered with the same precision and quality. We can create welding constructions up to lenght of 5 meters and a width of 3 meters. Contact us for your possibilities:

Delta Combiscope

SMI Plaatwerk builds the complete casing for Delta Instruments of the so-called combiscope. An ingenious device which analysis samples from milk, quickly and reliably. SMI not only produces all sheet metal parts, including the surface treatments, but assembles all parts (including purchase parts) into a completely assembled end product, this way the customer can build and test immediately upon arrival.

Laser cutting Parts

SMI Plaatwerk also supplies single, series-cut products. These parts, for example, are laser-cut, including the small holes with a total diameter of 0.6 times the plate thickness. After galvanizing, bearings are pressed in, all internal carried out by SMI. Deliveries are then carried out in specific Kanban trays, for direct delivery to the production without the need for further repacking.

Defense Vehicle

The Dutch defense takes a new type of off-road vehicle into use. SMI Plaatwerk, commissioned by Defenture, has built the frames. It concerns the chassis and the superstructure. These are for the new ATTV (Air Transportable Tactical Vehicle). This is the new lightweight vehicle of the commands. Defense has given the vehicle the name: Vector.
