First, the type of test
1. External characteristics test: type test, factory test
Type test: running test, performance test, cavitation test, noise test
2. Internal characteristic test: speed field measurement, blade surface tension measurement, flow display and pressure pulsation measurement
3. Strength test: axial force radial force measurement, hydraulic torque measurement
4. Other project tests: seal test, material test and energy balance test
Second, the test device
ER70S-3 is a silicon and manganese deoxidized wire used for mild and low alloy steel general purpose fabrication. A well balanced silicon and manganese content permits its use with CO2, Argon-Oxygen mixtures, or mixtures of the two. This wire may be used for short-circuiting arc (dip-transfer), buried arc, as well as spray transfer arc processes. ER70S-3 produces quality weld with rimmed steels, better welds on killed steels. It yields an almost slag-free deposit which does not require cleaning for many applications thereby providing low plate preparation costs, good bead appearance and welder satisfaction.
