Select a testing equipment category or inspection consumables line. Include component geometries, required sensitivity class, and metallurgical standards with your inquiry.
HELLMAG Stationary Magnetic Particle Testing Benches & Inspection Lines
HELLMAG Universal crack detection benches and Vario 2500 AC, 500/700 AC series systems provide non-destructive testing for ferromagnetic parts up to several meters long. The equipment applies combined circular and longitudinal magnetization, identifying surface flaws in a single cycle.
Features include pneumatic workpiece clamping, closed-loop fluorescent bath circulation, and automated demagnetization.
Selection inputs: part length and diameter, magnetizing current (AC/DC up to 6000 A), and demagnetization options.
Portable AC/DC Magnetic Inspection Yokes UM Series
HELLING portable magnetic yokes series UM-8, UM-9, UM-10 and HANSA 42 detect surface cracks across structural welds and pipelines. Articulated pole legs ensure firm contact with curved geometries.
Units operate on AC mains or Power Case battery packs, delivering lifting forces exceeding 4.5 kg in AC mode under EN ISO 9934-3.
Selection inputs: current mode (AC, DC), pole leg geometry, supply voltage, and Power Case battery inclusion.
ZERO Series Industrial UV-LED NDT Inspection Lamps & Panels
HELLING UV-LED inspection lamps including ZERO 700/6 IP54, ZERO Mini and modular ceiling panels provide excitation for fluorescent penetrant and magnetic particle testing.
Emitting an exact narrow band at 365 nm with white light emission below 20 lux, they comply with ISO 3059 and Rolls-Royce RRES 90061. Rugged aluminum housings use passive cooling sinks for continuous multi-shift operation.
Selection inputs: UV intensity at 380 mm (uW/cm2), beam footprint dimensions, handheld or overhead mounting.
NORD-TEST Liquid Penetrant Testing Systems & Consumables
The NORD-TEST family includes visible red-dye and fluorescent penetrants (U-87, U-88, Rot-3000), solvent cleaners U-89, and white non-aqueous developers U-89D in aerosols and bulk cans. Formulations penetrate sub-micron surface fissures in metals and ceramics.
Certified under EN ISO 3452-2 and ASME Section V, they feature ultra-low halogen and sulfur content for nuclear and energy metallurgy.
Selection inputs: sensitivity class (Class 1 to 4), testing temperature range (-10 to +100 C), and packaging volume.
The lineup contains high-sensitivity fluorescent penetrants Level 2, 3, and 4 (FP-923, FP-95A), hydrophilic emulsifiers, and developers Form a, b, c, d (D-70, D-72A, D-78B). The chemistry is dedicated to turbine blades and flight-critical aircraft components.
Selection inputs: AMS 2644 sensitivity (Level 1 to 4), removal method (Method A, B, C, D), and developer form.
Super-Magna materials (including LY 1500, LY 2500, GW 220, black and color powders) are indicators for magnetic particle testing under EN ISO 9934-2. Fine ferromagnetic particles with fluorescent coating create sharp indication patterns over micro-cracks under low field gradients.
Formulations are available as high-flashpoint oil mixtures or water concentrates with corrosion inhibitors.
Selection inputs: particle grain size, contrast color (fluorescent, black, red), and carrier base type.
Ultrasonic Matrix Flaw Detectors & Acoustic Wave Systems
HELLING supplies ultrasonic testing units including Dolphitech DC2 matrix flaw detectors, Koppelpasten couplant gels, and K1/K2 calibration blocks. Matrix transducer scanning provides real-time C-scan imaging of layered composites, polymers, and metals.
The equipment accurately measures internal delaminations, porosity, and wall thinning without destructive intervention.
Selection inputs: transducer frequency band (1.5–10 MHz), module configuration, thickness range, and software.
3D Laser Scanning Anti-Glare Sprays & Matting Suspensions
For metrological 3D laser scanning of reflective or transparent parts, HELLING provides 3D Entspiegelungsspray and Anti-Reflexionsspray MATT. Suspensions deposit a thin matte white film mere microns thick, suppressing glare and laser refraction.
The range includes sublimating formulations that evaporate within hours without leaving residue, eliminating solvent cleaning of parts.
Selection inputs: coating type (sublimating or washable), layer thickness, evaporation time, and canister volume.
Baseline Inputs for NDT System Engineering
Required inspection method (penetrant PT, magnetic particle MT, ultrasonic UT), part dimensions and geometry, metallurgical alloy grade, flaw sensitivity class, and inspection throughput targets.
Inspection Consumables & Operational Spare Parts
We deliver original NORD-TEST penetrants, Super-Magna magnetic suspensions, MET-L-CHEK aerospace materials, replacement ZERO UV-LED modules, transducer cables, and articulated UM yoke pole legs by factory part numbers.
Industrial non-destructive testing (Zerstorungsfreie Prufung, ZfP) engineered by HELLING spans four primary inspection modalities: liquid penetrant testing (PT), magnetic particle testing (MT), ultrasonic testing (UT), and visual inspection (VT).
Liquid penetrant inspection functions reliably on non-porous metals including stainless steels, titanium alloys, aluminum, and ceramics, detecting surface-breaking fissures and grinding cracks.
Magnetic particle testing is dedicated to ferromagnetic steel grades, locating surface and shallow subsurface discontinuities down to 2 mm depth via magnetic flux leakage.
Ultrasonic testing performs volumetric acoustic interrogation of material integrity, locating internal laminations and weld defects. Selecting the appropriate modality guarantees defect detection.
Magnetization Field Parameter Calculations on Stationary HELLMAG Benches
On HELLMAG Universal crack detection benches, combined magnetization is applied: circular magnetization (via current through the part) and longitudinal magnetization (via an external coil field). 4 kA/m according to EN ISO 9934-1.
Insufficient field strength prevents particle accumulation over hairline cracks, whereas excessive current causes background saturation. HELLMAG systems integrate stepless thyristor power regulation with Hall-effect sensors for closed-loop verification.
Penetrant Inspection Chemistry Certification under AMS 2644, ISO 3452 & ASME
HELLING NORD-TEST and MET-L-CHEK testing chemistry complies with international metallurgical codes: EN ISO 3452-2 (industrial standard), ASME Section V (pressure vessels), and SAE AMS 2644 (aerospace qualification).
For nuclear and aerospace components, strict limits restrict total halogen (chlorine, fluorine) and sulfur contents below 200 ppm each.
Residual halides and sulfur compounds catalyze stress corrosion cracking under elevated service temperatures, necessitating certified low-impurity penetrant chemistry.
Spectral Purity & UV-A Irradiance Thresholds at 365 nm under ISO 3059
Fluorescent penetrant and magnetic particle testing depend upon ultraviolet excitation centered at 365 nm (UV-A band) to trigger high-contrast yellow-green emission at 550 nm.
Under EN ISO 3059 and Rolls-Royce RRES 90061 specifications, UV irradiance across the inspection plane must exceed 1000 to 1200 uW/cm2 at 380 mm working distance, while ambient white light remains below 20 lux.
HELLING ZERO 700 fixtures incorporate optical Wood filter glass that eliminates short-wave UV and parasitic violet glare, protecting operator vision.
Metrological 3D Laser Scanning Technology with Sublimating Matting Sprays
Optical measuring machines and laser scanning arms encounter reflection distortion when measuring polished, chrome-plated, or transparent workpieces. HELLING 3D Entspiegelungsspray suspensions deposit a micron-thin diffuse matte white coating exhibiting high optical reflectivity.
The advanced sublimating formulations utilize cyclododecane chemistry: the applied film provides optical matting during data acquisition, then evaporates spontaneously into ambient air within 2 to 4 hours at room temperature, leaving zero particulate residue.
Matrix Ultrasonic Testing of Polymer Composites with Dolphitech DC2
Conventional ultrasonic testing of composite laminates (CFRP, GFRP) is impeded by high acoustic attenuation. 5 to 10 MHz. 25 mm for aircraft composite parts and structural panels.
Standard Test Panels, Twin KDS Calibration Standards & Sensitivity Verification
Daily operational verification of non-destructive testing systems before inspection shifts is mandated by ISO 9001 and NADCAP regimes.
HELLING manufactures certified verification artifacts: nickel-chromium Twin KDS panels with calibrated crack depths (10, 20, 30, and 50 microns), JIS test blocks, and Berthold magnetic flux indicators.
Twin KDS panels consist of matched pairs featuring identical roughness and crack profiles, enabling direct comparison between fresh and in-use penetrant materials.
