Welding work is controlled and performed in accordance with the standard ČSN EN ISO 3834-2. We weld S355/S420/S690 quality steels, we can also weld high-alloy austenitic steels, we carry out stainless welding with a welding robot (AISI 309, AISI 316). We are able to weld steel structures up to 40 tons.
Welding supervision is provided by two IWE (internationally qualified welding engineers). Qualifications of welding personnel: EN 287-1, EN 1418
Melting electrode in active gas
MAG Filled (tube) electrode in active gas
MCW / FCAW
Subassemblies up to 5000 kg, by MAG (MCW/FCAW)
MAG (MCW/FCAW) longitudinal welds up to a maximum width of 2 m, height of 2 m, length up to 12 m
Non-destructive methods – ultrasonic (UT), magnetic powder (MT), penetration (PT) and visual (VT) inspection.
Inspection is carried out by in-house NDT operators qualified to EN ISO 9712 – Level 2 (VT, MT, PT, UT)
Painting of products in ELFE, s.r.o. is based on the requirements of the NORSOK M-501 standard. The selection and application of coating systems is in accordance with customer requirements or meets customer specifications. Coating systems are applied to carbon-based steels and stainless steels using airless spray equipment. Coatings are carried out in close cooperation with the paint manufacturers (or their local representatives), all their instructions are followed (safety data sheets). Furthermore, technical specifications, drawings, work instructions or other special instructions are followed in accordance with the requirements of the general ELFE Coating Procedure.
The coating process at ELFE starts with surface preparation – cleaning with a high pressure water jet and solvents to remove all grease, oils, salts and other soluble contaminants. This is followed by blasting with GH25 steel abrasive in our 16 x 5.8 x 4 m blast chamber. The sandblasting of stainless steel materials is provided in cooperation. A blasting chamber of the same dimensions is used for coating application in the ELFE with temperature control and ventilation. We offer a variety of coatings and have experience with special systems such as multi-coatings.
All measurements and inspection results are recorded, records are maintained and traceability is ensured. The records are part of the final documentation package (MRB) that is normally provided to the customer. Tests such as salt test, dust test, roughness check and cohesive layer thickness, paint adhesion test (pull-off test on test panels) are carried out. Climatic conditions are also checked during application, such as air and steel temperature, dew point and humidity. All measurements are based on the requirements of the construction documents and other applicable related standards.
