Welding

COMPA has expertise in the following welding processes:

1. Gas shielded welding with consumable electrode ( MIG / MAG)

  • process 135 according to EN ISO 4063

Welding process MIG / MAG is usually used to achieve jointing material thickness of 1.5 mm ÷ 2 mm (parts for automotive shock absorbers, steering column components, platforms , platform extensions for elevators vehicles, etc.) up to thicknesses of 40-50 mm ( bridges for vehicles, bolts, joints, arms, etc).

MIG / MAG welding is also done in robotic version (four welding robots); automatic and semi-mechanized (manual drive of welding torch and wire feed is mechanically).

Robots MIG / MAG:

  • welding robot with 6 internal axes and two external axes CLOOS ROMAT 320
  • welding robot with 6 internal axes CLOOS ROMAT 350
  • welding robot with 6 internal axes CLOOS ROMAT 320
  • welding robot 6 internal axis ABB IRB 1600

Equipment for MIG / MAG welding:

  • Fronius Trans Pulse Synergy 4000 – welding installation with pulsed arc for MIG -MAG, WIG and coated electrode. We weld classic steels, galvanized sheets, stainless steels and aluminum.
  • Miller Blu – PAK • 45 – with welding source rectifie
  • CLOOS GLC353 MC3 – power source for arc welding without pulse, synergic arc welding without pulse, synergic welding with arc and pulse, WIG welding and welding with coated electrode.
  • CLOOS GLC553 MC3 – power source for arc welding without pulse, synergic arc welding without pulse, synergic welding with arc and pulse, WIG welding and welding with coated electrode.
  • Electric welding KempoMig, Sarazin

2. Spot and projection welders

  • process 23 according to EN ISO 4063

Method for pressure welding, derived from spot pressure welding, which is achieved by embossing(bosses) that melt when high electric current is passing (thousands or tens of thousands of amperes).

Air pressure welding:

  1. installation of point welding and embossed welding TECNA 8007N image005
  2. embossed air pressure welding BP160
  3. Spot pressure welding installation PPU100
  4. pressure welding installation NIMAK used for balancing of cardans.
  • Welding Processes – qualified according to EN ISO 15614-1/2008.
  • Destructive and non-destructive control (with penetrating liquid)
  • Qualified welders – certified according to EN 287-1/2012
  • Operators robotic welding – certified according to EN 1418:2000 also through ISIM
  • International/ European welding engineers (IWE / EWE).

3. Plasma arc welding

  • process 15 according to EN ISO 4063/2000

suduraPlasma Welding performed on automatic welding equipment, provided with microprocessor,  video cameras for process control, sensors for preventing errors and nonconformities (Poka Yoke), etc. Welding devices and automation are made in COMPA – design, manufacture and automation

In COMPA austenitic stainless steel components for the turbocharger exhausting gas from diesel engines are plasma welded.

 

4. WIG welding with solid filler material (wire/rod)

  • process 141 according to EN ISO 4063/2000

In COMPA carbon and stainless steel parts are WIG welded. WIG welding is also used for reshuffling small defects of seam welding. WIG welding is performed on fully digitized FroniusTransPuls Synergic (TPS) 4000 equipment,  inverter driven and microprocessor controlled. By WIG welding the protective gas used is argon.

Other welding processes available in Compa:

Friction welding – process 42 according to EN ISO 4063/2000

Shielded metal arc welding – process 111 according to EN ISO 4063/2000

Oxy-acetilene welding – process 311 according to EN ISO 4063/2000
