Activities & Expertise

joining & assembly

Joining and assembly at OCAS cover a large range of material types, thicknesses and industrial applications. We optimise your component and manufacturing route for assembly through welding, joining or adhesive bonding. Our facilities include all major arc welding processes – MIG/MAG, PAW, 5-wire SAW, TIG, MMA.  In addition, we are equipped for brazing, braze welding and adhesive bonding.  

You can benefit from our vast materials expertise, covering the full range of steel grades, including coated steels, as well as other materials, in a large thickness range from less than 1 mm to more than 200 mm. 

OCAS performs welding procedure development and qualification to relevant standards and is furthermore fully equipped to evaluate the welded joint in terms of mechanical properties. Our experienced welding team can advise you on further optimisation of your welding process, including the introduction of novel techniques. Allied technologies available include heat treatment and non-destructive evaluation of welded joints. OCAS proposes a method for early detection of weldability issues based on metallurgical investigation of the pipe material behaviour, simulations and stress corrosion cracking tests. Thus avoiding problems during the welding procedure qualification.

OCAS created a dedicated task force to support key accounts in ensuring the reliability of their safety-critical industrial assets. This team offers a versatile skill set in welding, corrosion, fatigue and fracture. We are confident we can add value by supporting our customers in asset integrity management and de-risking of capital-intensive projects.

To minimise your health and safety risks in the welding shop, we offer technical support in the field of air quality and welding fumes. Our extensive spectrum of sampling – from gas to dust – and analytical techniques available – from composition to particle morphology – completes our offer for fume analysis.

Our dedicated adhesive bonding lab is fully equipped to apply and test strength and durability of structural bonds.

Our welding team has highly skilled and experienced operators. All our welding project leaders are EWE/IWE qualified. Since 2012, one of our senior research engineers welding chaired sub-commission C-XI-E ‘transmission pipelines” of the International Institute of Welding (IIW) and was furthermore elected representative on the technical management board of IIW.  Since 2008, one of our senior project leaders of the surfaces department chairs the sub-commission Health & Safety for Welding of the Belgian standardisation body.
