In 2016, L&S Technischer Handel GmbH experienced an increase in order volume. The constantly high utilisation of production capacity resulted in enormous pressure and a longer delivery time, and made CEO Torsten Lezius realise that something had to be done. An investment in a CoWelder solution enabled the company to produce to order rather than for stock. L&S manufactures rather small batches of 50-800 units and in different variants, which would result in significant costs related to the time and resources of a programmer to program and alter a traditional automated solution. In light of this fact, L&S‘s local welding-equipment dealer turned their attention to, and demonstrated, the enormous flexibility of the CoWelder solution.
“We are pleased with the CoWelder because programming components and switching from one component to another is easy – its flexibility is amazing” – Torsten Lezius, CEO at L&S Technischer Handel
The flexibility exceeds expectations
L&S manufactures spare parts for a variety of types of waste containers, roll-off containers and ASP containers. Owing to its many end products, the product range has grown tremendously over the years.
Because of customers’ irregular ordering behaviour, it is not possible to keep all spare parts in stock. Rarer components are produced to order, which requires extra flexibility by the welding staff. As these components are typically exposed to enormous loads, welds seams have to be of high quality. And of course, L&S had similar high expectations of the CoWelder solution.

“We have started producing for stock again. It used to take at least twice the amount of time for the same volume of production. For some components, we are able to reduce delivery time from two weeks to one. And we are glad to say that basically our proficient welders are not burdened by it. Components lie ready in the evening as if by magic.” – Torsten Lezius.
Operating the robot is easy
Operating the CoWelder, i.e. placing components in fixtures, starting up the welding and subsequently removing the components is typically dealt with by staff operating a saw close-by.
Any waiting time at the saw can be optimally utilised by operating the CoWelder™. Programming and setting the system is dealt with by Torsten Lezius or a technician.
Once the process has been set and the first components have been flawlessly welded, saw operators take over. They only need some quick and simple guidance on safety and how to operate the CoWelder. Accordingly, optimal utilisation of time minimises wage costs and improves productivity.
The employees had a very positive attitude to their new ‘colleague’, which made it easy to introduce the CoWelder into their daily work. They never saw the robot as a rival, but used it from day one to carry out previously tedious tasks.
Torsten Lezius was surprised to see the creative abilities of his employees and their ability to find additional components that could be produced faster, better and more cheaply using the CoWelder.
The mounts are easy to place in the fixture which accommodates ten mounts in two rows. Welding four mounts takes around 1.10 minutes. Roller holders for containers are also produced in different sizes. On each roller holder there are twelve fillet welds, eight of which are in a downward position. Welding time from beginning the first weld to finalising the last weld has been reduced from approx. 5 minutes to 2 minutes and 27 seconds. Moving the component on the welding table used to be very time-consuming. L&S produce steel containers in different sizes (length, inside and outside diameters) and in batches of several hundred. On each side of the component, the axle bushings are welded with two circular fillet welds. Semiautomatic production with CoWelder has clearly improved both production speed and welding quality.
