We have initiated a project to streamline production using the Lean and 5S methods. The aim is to make production more efficient and to improve turnaround times.
Joni Kähkönen has enjoyed work as a sheet metal worker at Simetek for almost 11 years. He specialises in lead burning and aluminium welding.
Kähkönen’s typical job description involves manufacturing leaders for Junttan’s piling machines. In addition to made-to-measure work, he also repairs and restores rollers, containers and conveyor parts, for example.
Most of the time Kähkönen works at the workshop. Installations on customer sites and a diverse range of jobs bring variation to his work.
“At Simetek there’s not often much need to do large series of line production, and the jobs vary. The materials also vary from aluminium to stainless steel and from structural steel to special steels,” says Kähkönen.
Kähkönen’s favourite material is black steel.
Sheet metal working and welding methods
Kähkönen mainly uses a welder and angle grinder in his work, but when working with sheet metal he also uses a press brake, mangle, flame cutting torch and handheld tools.
Lead burning is a more challenging technique than normal welding. It differs from normal welding due to its low melting point, which is just over 300 degrees, while steel has a melting point of over 1000 degrees.
“In practice, lead burning is gas welding in which lead is melted using small gas tubes,” explains Kähkönen.
The toxicity of lead sets its own requirements for protective equipment. Typically, this method is only used at sulphuric acid plants. Read more about lead burning…
The atmosphere at work
Kähkönen says the atmosphere at work is good, and everyone gets along with one another. Evenings out with other members of staff increase team spirit. Colleagues from different units engage in discussion and exchange views.
“We listen to each other’s opinions and solve challenges together.”

Laser scanning works excellently when designing new steel structures among existing structures.
Is your plant building missing drawings, or have modifications been carried out retroactively? Do you need information on the size of beams or pipes in the ceiling, for example? Scanning means that there’s no need for a tape measure, and you can even measure areas that are unreachable in person. Scanning also minimises measurement errors.
What is laser scanning?
Laser scanning is a method that is used to create a 3D image of existing structures. In practice, it is the measurement of distances. The device scans the distance from its own position to its surroundings. The measurements are then used to model a point cloud model which shows the forms of the measured site.
Work begins by specifying settings for the scanner regarding the location and whether lighting must be considered. The device can also be told how far it should measure. It can scan a maximum of 130 metres.
The scanner rotates around its own axis and measures the site using a rotating lens which projects a laser around it. The data collected by the device is opened on a computer and the scans taken from various points are combined into a single, large point cloud. If, for example, you wish to measure a container, it should be scanned from several directions, or the scanner will see the same thing from a single direction as a person.
The device also takes panoramic photographs of the site, which can be used afterwards to check what the space was actually like. The picture can be useful afterwards to confirm e.g. the location of pipes.
Laser scanning is so precise that in practice even such small elements as bolts can be seen in the point cloud produced from the measurements.
In which kinds of projects does Simetek use laser scanning?
We use laser scanning in the design of steel structures, container lids, work platforms, access routes, pipelines, conveyor and material feed systems and various production structures and devices.
We offer laser scanning as part of our design services because we want to provide our customers with a comprehensive service. Scanning eliminates measurement errors and allows us to see the current structures without old drawings. It is easy to see, for example, which kind of working platform will fit among existing structures using the laser scanning measurement data.
The point cloud model created from the laser scanning data also shows us where we can find surfaces to attach new steel structures.
We use a FARO Focus 3D x 130 laser scanning device in our measurements.
How does a laser scanning project progress?
To begin, we determine the aims of the measurement together with the customer and visit the site. We remove all unnecessary objects from the area that can disrupt the scanning, such as tools and dirt. Then we laser scan the space.
Scanning and data processing on the computer takes around a day before it can be utilised in design. After this, we can begin preplanning and planning.
Many of our customers who are located far away have been satisfied that measurement is successful in a single visit.

Simetek Works Oy took a CNC-controlled horizontal milling and boring machine into use in production in early February 2015. The milling and boring machine is a CNC-controlled TOS WNH 13.8 with a range of movement of X=3500mm, Y=2500mm and Z=1250mm. The table’s load-bearing capacity is 12 tons. The machine makes it possible to machine challenging pieces with minimal attachments.
Simetek Works Oy expanded its premises by 2,700m2 in 2014. “It was time to expand our premises as we wanted to offer even more comprehensive services to our customers, and our old premises weren’t large enough to do so,” explains Managing Director Kari Roivainen. “The new premises increase welding capacity and allow us to carry out large and heavy assemblies right to the end customer. We have already taken some of the new premises into use and the rest will be in used in production by the end of the year,” Roivanen adds.
Simetek Works Oy has also invested in machines. The largest is the TOS WNH 13.8 CNC-controlled broaching drill, which allows for the machining of large and heavy pieces. “The machine will be implemented in early 2015,” says Roivainen.
DEKRA Certification Sp.zo.o has awarded Simetek Works Oy EN 1090-1:2009+A1:2011 quality certification in implementation classes EXC1, EXC2 and EXC3 concerning the design, manufacture and installation of steel structures. The certificate entitles the holder to use the CE marking on its products.
