PV welding with a tensile strength testing machine is a mechanical testing instrument. Main accurately strike a metal or non-metallic, composite materials at room temperature strength, modulus, elongation, yield and mechanical data. Used primarily as universities, research institutes, medium and small enterprises, the mechanics of materials testing. Exactly in accordance with the GB and foreign standards testing materials. Tensile strength is the plastic deformation of the transition metal consists of a uniform plastic deformation is locally concentrated critical value, also a metal or metalloid under conditions of static tensile stress of the maximum load. Usually by "MPa" or "kgf/mm2" treated as a unit. PV welding with a tensile strength testing machine specific parameters are as follows: Technical parameters Main specifications valid Model Model: QX-W400, maximum load Max capacity: 5000N (arbitrarily selected), load cell accuracy of the Load Accuracy: 0.01% 4 test Accuracy Measuring accuracy: <± 1%, Operation Control: full computer control 6, the effective width of the Valid width: 150mm 7, effectively stretching space Stroke: 800mm (needed heightening) test speed Tetxing the speed: 0 ~~ 500mm/min any tune, speed, accuracy Speed ??Accuracy: ± 0.5% or less; 10, displacement measurement accuracy Stroke Accuracy: ± 0.5%; 11, deformation measurement accuracy Displacement Accuracy: ± 0.5% less than 12, the safety device Safety device : Electronic limit protection, emergency stop button the Safeguard stroke 13, the weight of the machine Main Unit Weight: about 85kg
