Welding

Whether using a robot or manually: With us, all welding jobs are exactly executed with the greatest precision.


Robotised welding

Robot welding is particularly suitable for repetitive processes in production, as it fulfils its tasks continuously and with millimetre accuracy. Here, the same quality is always pursued. By this method the cheapest possible approach is applied.

With us, the welding processes         

  • MAG
  • MIG
  • WIG

are applied to steel, stainless steel and aluminium.


Data:

  • Dimension parts: max. 2300 x 1000 x 1000 mm
  • Table: Turn-over table with universal clamping supports and 2 stations

Advantages offered by robotic welding are:

  • the limitation of processing time
  • the achievement of a homogeneous welding quality
  • the continuous use of once-programmed instructions
  • the consideration of the health aspect

Spot welding

Not only accurate to the point, but also very stable, the workpieces are inseparably joined together by the creation of a current flow in this way of working.

When the previously-machined workpiece has cooled down, you can see a "brown ring" at/on both sides, demonstrating the best quality of workmanship.

You can find this indication of very good workmanship with us in steel and stainless steel up to a thickness of 6 mm and in aluminium up to a thickness of 3 mm.

For spot welding we use the spot-welding machines "Dalex", "Peco“, "Nimak" and "Messerer-Griesheim", as well as the spot-welding gun C-Form MIDIspot Vision.

Spot-welding tongs C-Form MIDIspot Vision:

  • Water-cooled electrode arm
  • Digital control with quality monitoring
  • Sheet-specific programmes with the available parameters of the automotive industry
  • Fully-automatic welding tongs with a pulse-sonar measuring system
  • Automatic material detection; Automatic adjustment of the electrode force

CNC stud welding with tip ignition

Last but not least in our assortment is the Soyer KTS-200 machine which helps us with the method of stud welding.

By melting the stud directly at the point to be fastened, the tip ignition is a very time-saving process and can be applied to aluminium, steel and stainless steel.

Soyer KTS-200

  • Clamping surface: 2000 mm x 1500 mm
  • Work area : Y-axis 1500 mm
  • X-axis 1000 mm repeatability: < ± / 0,1 mm

Manual welding

Even with manual welding, the

  • MIG
  • MAG
  • WIG  techniques are used.

At separate welding and grinding workplaces, steel, stainless steel and aluminium are processed by Fronius welding machines by the competent hands of our employees.



Painting

Sedlbauer AG is particularly proud of the paint shop located in-house. In this department, your orders and requests can be customised individually. By using the Eisenmann Power and Free Transport system, we offer the best results in the processing of solvent-based and water-soluble paints.

During the painting process, the workpiece goes through several steps until it is finally ready for dispatch.


The first step is pre-treatment”. Depending on size and requirements, the piece undergoes a spray or dip treatment. In these steps, care is taken to remove any obstructions that may damage the paint. The process steps of pre-treatment are: De-greasing/cleaning, pickling, activating, phosphating, nano-coating and conversion coating.

The painting itself is the second step. With a throughput of 5000 kg/h and a paint shop of 22000 mm x 1000 mm x 1252 mm, the workpieces are painted according to the orders by using spray booths.

As soon as the workpiece has been painted, the paint is dried and strengthened with the aid of a baking oven, which can reach temperatures of up to 160 °C.

By investing in Eisenmann environmental technology - which places emphasis on a CO2-friendly and resource-saving working process - we are committed to sustainable climate and environmental protection.

Screen printing

There are almost no limits to the processing of metal using the screen-printing technique. In screen printing, a fabric is attached to the ends of the frame; with exceptions at the places where the paint should penetrate - later the motif - this fabric is covered with a colour-impermeable coating. Now the colour is printed on the material with a rubber squeegee through the fabric. Once this is done, the paint is baked again.

This method allows printing on a variety of materials, whether moulded or flat, with or without motif.

Pickling & Passivation

Pickling usually refers to the chemical removal of impurities from the surface of stainless steel, so that a metallically-clean surface is formed on which the protective passive layer can form. This staining leads to the formation of a protective layer on the metal, which prevents oxidation.

Application:

  • Formation of an intact passive layer in stainless steels, nickel-base alloys and titanium
  • Pre-treatment before electro-polishing, chemical deburring, polishing, anodising or electro-plating in normal steel, copper materials and aluminium




Benefits:

  • direct application to temper colours and pickling seams
  • intensive cleaning and activating of metal surfaces
  • gives surfaces a matte to silk-gloss look


During passivation spontaneous formation or targeted development of a protective layer, the passive layer, occurs. This can be done either naturally by moisture and oxygen or chemically by passivation chemicals. Here, the duration of the process is the only essential aspect that serves as a distinguishing feature. What in the natural way takes several days, will otherwise take a few minutes. Since only metallically-pure surfaces can be passivated, it is advisable to connect this step with the pickling.

Applications:

  • Vehicle construction / boat building
  • Machine enclosures
  • Switch cabinets
  • Fastening elements
  • Medical technology


Benefits:

  • Application possible on any surface finish
  • Removal of rust and corrosion products
  • Resistance improvement against pitting and stress corrosion cracking
  • Removal of ferritic impurities
  • Application to all alloys with a chromium content of more than 15%
  • Enhancement of the resistance against thermal discolouration by approx. 150°C


Assembling / Electrical assembling

From the manufacture of battery chargers to e-mobility charging stations for private use, we offer a wide range of options to make the workpieces according to your wishes.

An addition to our mechanical assembly we offer the ESD range for electrical installation. This is characterised by access control, ESD clothing, daily checks and the intensive training of the staff.



Soldering

In general, soldering is a thermal process for the indissoluble bonding of two or more pieces of metal together by the addition of a molten metal material (solder). Since the melting temperature of the solder is below that of the base materials, the material to be joined can be wetted with liquid solder. Due to contact with the liquid, the surface of the base material dissolves and forms an electrical intermetallic bond.


Manual soldering

Lead-free manual soldering requires a lot of skill, accuracy and know-how from our employees to achieve the best results.

The advantage of this method consists in the simplified and more accurate implementation of multi-layered circuits, than would be possible with machines.


Wave soldering

In addition to ubiquitous manual soldering, there is also wave soldering. This is a method for electronic assemblies for mass soldering. This method is divided into 4 steps; flux application by spray flux, pre-heating, soldering and cooling. During the soldering process, the printed circuit board is transported over a solder wave and wetted at a usable solder width of 400 mm. The solder joints form on the solder pads removed from the stop paint.

Benefits:

  • economical, due to reduced time expenditure
  • inexpensive
  • lead-free
