Manufacturing welding technology

Connections are essential!

Decades of experience in welding technology qualify us to be a good consultant when it comes to "connections". Whether individual manual welding with state-of-the-art validated welding machines or by means of the latest Panasonic robot for series production.

We weld safely and under the supervision of professionally experienced welding personnel. In addition to fully integrated custom solutions, we also offer welding in our "standard" welding cells. PWS welds assemblies of standard and stainless steel, aluminum and also special materials.

Quality assurance is guaranteed by both destructive and non-destructive testing.

We offer you:

  • Robot welding
  • Projection welding
  • Spot welding
  • Stud welding
  • 3D laser welding
  • TIG welding
  • MIG/MAG welding

Automated robot welding

Great precision – consistent quality

Precise joints and a consistently high weld seam quality are defining features of automated robot welding. Within the scope of our production, we generally count on this technology when processing unalloyed and high-alloy steels as well as aluminium. Processing other materials or mixed joints with the help of robot welding requires an individual assessment. We clarify the respective wishes of our customers individually on request.

The advantages of robot welding, such as a short processing times or integrated quality assurance, are already available for small series. Our production has the most state-of-the-art compact cells, which are equipped with 7- or 8-axis robots with turning and tilting devices. As a rule, the systems provide a wide radius of action and corresponding capabilities to carry out welding work. The maximum working space is two times 1,000 x 800 mm with a turning diameter of 900 mm.

For robot welding, we employ the following processes:

  • Spray-reduced MIG welding up to 350 A (metal welding with inert gases)
  • MAG welding up to 350 A (metal welding with active gases)
  • Laser beam welding up to 4 kW
  • Spot welding with C-type gun

Making strong connections

Economy and high performance characterise the resistance welding process

Resistance welding is characterised by high energy efficiency, low component distortion due to the welding heat and the possibility of extensive automation. This is just one of the reasons why we often use projection and spot welding processes to join sheets and components. Both welding processes are also very advantageous from an economic point of view. Fast, precise and high-quality connections can be made comparatively inexpensively with projection and spot welding processes.

In terms of the materials to be joined, we mainly process unalloyed and high-alloy steels as well as galvanised and aluminised sheet metal. The processes described are also used for the assembly of weld nuts, special nuts and threaded connectors, mainly in the field of assembly production.

Automated processing

State-of-the-art machines guarantee the precision of the results of our resistance welding processes. We continuously invest in our manufacturing capabilities to ensure high quality in the field of welding technology. We have a machine park with the following systems at our disposal for the automated processing of components and component parts:

  • Spot welding machines
  • Projection welding machines
  • Special spot and projection welding machines
  • NC threaded bolt welding machines (up to M8)

Manual welding – Skilful connections

Manual MIG/MAG and TIG welding ensure first-class welding results

Even though manual welding is one of the oldest welding techniques, it is still indispensable in everyday metal processing. We often rely on the individual skills of our experienced welders to process unalloyed and high-alloyed steels as well as aluminium and titanium. Depending on the task at hand, we use the following processes:

  • MIG/MAG welding
  • TIG welding

We rely on the generally acknowledged procedural advantages in the field of manual welding as well. MIG/MAG welding, for example, allows a rapid work progress as well as a high welding volume. At the same time, MIG/MAG welds stand out for their quality and precise execution. They are also an economical way of welding components and workpieces together in an uncomplicated and safe manner.

The TIG welding process is another option we count on in the field of manual welding. The advantage of this process is its high weld seam quality and its versatile range of applications for a wide variety of materials. In addition, the process also produces very delicate weld seams.

Our employees have generous conditions with regard to the infrastructure for manual welding work. Powerful manual welding equipment (AC/DC up to 400 amps) and turn/tilt tables that can bear loads of up to 750 kilograms offer ideal conditions for sophisticated welding results.

Our technologies

As a highly specialised partner in metalworking, we offer a wide range of manufacturing options with a high level of vertical integration. To achieve this, we use modern technologies and are constantly optimising our processes. In addition, our well-equipped machine park is complemented by the wealth of experience of our employees. Altogether, PWS can draw on over 80 years of experience in metal processing.

With a practised eye, we recognise areas of potential and sound out new technologies. This is also evident in the youngest member of our production chain: the “Cutting” competence centre. We then offer the new and optimised capabilities to our customers as a full-service supplier.
