Welding Material Testing

The Welding Consumables Testing Laboratory conducts routine commissioned inspections of welding materials, product quality arbitration, and weldability assessment, providing services such as quality control, batch-to-batch consistency verification, and weld procedure qualification for welding material manufacturers and fabrication enterprises. It also offers testing support for new-material research and development at universities and research institutes. The laboratory is the only facility in China equipped with a comprehensive suite of instruments and methodologies for determining diffusible hydrogen in weld metal, including the mercury method, glycerin method, thermal conductivity method, and gas chromatography. Over more than two decades of development, diffusible hydrogen measurement has gained widespread recognition among welding fabrication companies and welding material producers.

Scope of Business

Comprehensive performance testing of welding electrodes, solid welding wires, flux-cored wires, submerged-arc welding wires, welding strips, fluxes, and brazing materials.

Determination of Diffusible Hydrogen Content (Mercury Method, Thermal Conductivity Method/Carrier Gas Thermal Extraction Method, Gas Chromatography, Glycerin Method)

Determination of Ferrite Content in Weld Metal (Magnetic Method, Metallographic Method, Chemical Method)

Detection of wire feed stability and arc stability in welding materials

Testing of brazing material melting temperature range, wettability, spreadability, and gap-filling performance

Powder particle size distribution: particle size distribution curve ranging from 0.01 to 3,500 μm

Areas of Involvement

Construction machinery, offshore and cryogenic engineering, bridge construction, ultra-supercritical boilers and large-scale petrochemical equipment, military and nuclear power projects, shipbuilding, aerospace, rail transit, and pipeline engineering.
