Anatomy of chemical elements

Chemical elemental analysis generally refers to the analysis of metal composite materials, stainless steel plates, etc.

Detection of metal materials: cast iron, stainless steel plate, steel rod wire, standard parts, rare metals and products, various metal production, etc.

Metal alloy inspection: aluminum alloy profiles, titanium metal, light aluminum alloys, electric sliding doors, auto parts, various metal products, etc.

Stainless steel detection: grade identification, tensile test, elemental analysis, compression test, tensile test, etc.

Non-destructive testing: flaw detection of pipelines, non-destructive testing of machinery and equipment, flaw detection of standard parts, flaw detection of heating furnaces, flaw detection of metal structure production, etc.

Inspection of welding consumables: welding wire, flux, welding rod, gas cutting, fiber solder, etc.

Coating coating control: coating, alloy coating, metal coating, electroplating

Inspection of the solar pole: zinc layer adhesion, zinc layer uniformity, support frame flexibility, toughness, toughness
