Welding accident causes: 1, welding and cutting jobs, especially when gas cutting, the use of compressed air or oxygen jet stream, so Mars, bead and iron slag splash (the larger bead and iron slag can splash to from places other than the operating point 5m), when the operating environment in the presence of flammable, explosive materials or gases when, on fire and explosion may occur. 2, welding and cutting operations at high altitude, inflammable and explosive materials on Mars within the scope that is not clean, workers throw welding head during operation, after the job is not thoroughly check the left fire. 3, gas welding, gas cutting in the course of their work according to the specified requirements placed acetylene generator, before the work was not required to check welding (cutting) safety devices torch, rubber tubing and acetylene generator. 4 cylinders deficiencies formulation, there is insufficient storage cylinder filling, transport, use, etc., and other violations of safety rules. Develop 5, acetylene, oxygen and other pipes, defective installation, use did not timely detection and rectification of its shortcomings. 6, when the fuel container and pipeline welding, did not seek to take corresponding measures. Welding of stoppage time in the implementation of the replacement, the replacement is not complete, with the implementation of the pressure is not enough to cause displacement welding of stoppage time pressure and importing external fire. Ultrasonic plastic welding principle: when the ultrasonic acts on the thermoplastic plastic contact surface will produce tens of thousands of times per second, high-frequency vibration, which reach a certain amplitude of high-frequency vibration, by weldment to transmit ultrasonic energy to the welding area, Since the welding area at the interface of two welded large acoustic impedance, thus resulting in local temperature. Also, because the poor thermal conductivity of plastic, for a moment, can not be distributed, gathered in the weld zone, resulting in two plastic contact surface rapidly melting, soldering equipment suppliers to find Huizhou Huashi welding, with a certain pressure, CCTV advertising partners - Huizhou, China Guests welding, to get together. When the role of ultrasound to stop, so the pressure for a few seconds, solidified forming, thus forming a solid molecular chain, to achieve the purpose of welding, welding equipment, welding strength can be close to the raw strength. Ultrasonic plastic welding is good or bad depends on transducer horn amplitude, three factors applied pressure and welding time, welding time and welding head pressure is adjustable amplitude is determined by the transducer and horn. These three have a suitable amount of interaction value, when energy exceeds the appropriate value, the amount of plastic melting on the large, welding material deformation; if the energy is small, easy to weld, the applied pressure can not be too large.
