HUALONG WCJ Series is mainly used for drop weight tear test (DWTT) of Ferritic Steels, to observe specimen fracture surface after impact within the temperature that fracture type is converted from non-ductility to ductility. This test method is that hammer striker with some weights is raised to some height then released. Free drop hammer impacts and tears the specimen. After impact, observe shape and features of fracture surface.

Features

• Drop weight tear testing (DWTT) of “Specimen” according to standards as per ASTM-E 436, API-RP5L3, ASTM-E 208 and DIN EN 10274.
• Touch-screen Panel with electronic display of height , energy, drop weight and velocity at predetermined parameters
• The stepped adjustable drop height is reached automatically after input of drop weight and energy.
• Drop weight is divided in individual weights to adjust drop energy.
• Modular frame design with stainless steel pillars and doors.
• Four high capacity hydraulic shock absorbers with accumulators for safe absorption of the excess drop energy.
• Hydraulic specimen feeding device, equipped outside of testing area.
  Easily removable bending tools (Hammer).
