high-frequency induction heating welding equipment

2012-07-17 by seoer8

High frequency induction heatingWelding Electrodes in the harmonic lattice theory, the use of new high power power electronic devices ICBT and lock ring technology, high performance heating power, the power factor close to 1, the maximum power up to 100KW, can completely replace the high consumption can tube super audio power, the machine frequency power supply, and refined gate tube heating power. High-frequency induction heating welding equipment can be instantly heated to the desired temperature, its melting point metal objects; but also local heating of metal objects. High frequency induction heatingWelding Rods for efficient energy saving machine machine efficiency ≥ 95 than the tube energy-saving equipment 30-40% power, suitable for automatic production line of electronic control and monitoring holes protection system is comprehensive and reliable and can often start to start the success rate of 100% output constant power, constant voltage, constant current load to adapt to a wide range of easy to adjust .
Because of the high frequency induction heating welding equipment has a small size, light weight, low failure rate, energy-saving and welding point firmly exquisite beauty, the weldment geometry unrestricted surface pattern will not damage the metal internal crystal structure unchanged, annealing small range, no significant burr is widely used in metal glasses manufacturing, electrical connector of the electronics industry welding, small relay inside the contact welding, refrigeration industry, high pressure resistance welding, welding various parts of the jewelry industry and metal jewelry and metal craft manufacturing of welding. Same heat welding of high-frequency induction heating welding equipment heating welding revolution

the welding harmful to the human factors characteristics

2012-07-18 by seoer8

(1) Welding of Industrial Hygiene and the main object of study is Welding Wires, which of Industrial Hygiene and the biggest problem the next arc welding, submerged arc welding, electroslag welding at least.
(2) The main harmful factors of the coated electrode manWelding Material, carbon arc gouging and CO2 gas shielded arc welding of soot generated in the welding process, welding fumes. Electrode manual arc welding. And carbon arc gouging, the restricted space in the operating environment for a long time (boilers, cabin, sealed containers and pipelines, etc.) welding operation, and bad for Health Protection will have respiratory hazard, and in severe Yi the risk of electric welding pneumoconiosis.
(3) toxic gas is a gas welding and plasma arc welding of a major harmful factors in high concentration can cause poisoning symptoms. In particular, ozone and nitrogen oxides, they arc high-temperature radiation acting on oxygen and nitrogen in the air. (4) arc radiation is all out arc common harmful factors, and the resulting electro-optic eye disease is a special occupational diseases in the next arc. Arc radiation will damage the skin, welders suffering from skin diseases such as dermatitis, erythema and small blisters. In addition, damage to the cotton fiber.
(5), gas tungsten arc welding and plasma arc welding, the welder to set up high-frequency oscillator to help arc, so the existence of harmful factors - high-frequency electromagnetic fields, especially high-frequency oscillator work longer welder (such as Some factories homemade welding machine). The high frequency electromagnetic field will welders suffering from diseases of the nervous system and blood system.
