1.2mm-3.2mm TIG Welding Wire development application
1.2mm-3.2mm TIG Welding Wire has been developed and used widely in different periods and regions. 1.2mm-3.2mm TIG Welding Wire has maintained a high speed increase. China has been a big country with 1.2mm-3.2mm TIG Welding Wire production and consumption application. Since the 50 s of the 1.2 mm to 1.2 mm TIG Welding Wire, mainly from the former Soviet union's calcium titanium slag system and the system of raw materials, it has low cost, easy pressure, stomatal resistance, mechanical performance is good wait for an advantage, but similar with European famous brand 1.2 mm to 1.2 mm TIG Welding Wire electrode compared to red serious, big splash, deslagging and poor forming, low Welding efficiency and large waste, so since the mid - seventy - s to the early eighty s, in view of the domestic import electrode some domestic scientific research institutions cooperate with electrode production enterprise, is 1.2 mm to 1.2 mm TIG Welding Wire coated red off cause and the solution are studied.
On the one hand, they think their research work is meaningful and make a lot of progress. On the other hand, by the several of the 1.2 mm to 1.2 mm TIG Welding Wire after the actual test, also think is still obvious gap with foreign products, but since then, the domestic research in this field is in the situation, step back from the early 80 s to the early ninety s decade due to we have that there is no weight of 1.2 mm to 3.2 mm TIG Welding Wire research literature. Since the early 1990s, the research on 1.2mm-3.2mm TIG Welding Wire has become more active. 1.2mm-3.2mm TIG Welding Wire manufacturer also gradually increased. In the late ninety s to the early part of this century, the domestic 1.2 mm to 3.2 mm TIG Welding Wire and studies have sprung up, although its level itself does not exceed the two existing levels, but for active academic atmosphere, to strengthen learning communication is still good.
Foreign stainless steel industrial production began in the early 20 s, followed by the corresponding 1.2 mm to 1.2 mm TIG Welding Wire, TIG Welding mature 1.2 mm to 1.2 mm Wire products appear in around 1965, represented by European countries, especially in Western Europe Sweden, a population of only 8 million or so, and focus on the ESAB, AVESTA and SANDVIK world-class stainless steel Welding material manufacturer, which the AVESTA buffalo card 1.2 mm to 3.2 mm TIG Welding Wire is 1.2 mm to 1.2 mm world TIG Welding Wire model. Japan, Taiwan and south Asian countries have 1.2mm-3.2mm TIG Welding Wire technology based in Europe.
1.2mm-3.2mm TIG Welding Wire has many different models and types in the long-term use. 1.2mm-3.2mm TIG Welding Wire has gradually formed a production system based on several products. Laser welding, the principle of deep penetration laser welding belongs to welding, is the laser energy can be converted to heat, melt docking part of the workpiece, the formation of molten pool, the formation of weld in the subsequent cooling process. Core is small effect of the laser welding, laser deep penetration of the energy transfer and conversion is done through the holes, under the high power laser beam, by tiny local welding metal materials by heating, melting and evaporation, forming holes, through the effect of laser beam, the hole wall materials of the steam evaporation is full of holes in a row, forming high pressure air hole, the surrounding molten metal into the square, the laser beam through steam hole through material inside.
As the laser beam and the workpiece move, the molten metal moves forward at the speed of a moving beam or workpiece in the form of a small hole, which then cools and solidifies into a uniform tight metal weld. 1.2mm-3.2mm TIG Welding Wire affects the quality of welds of weld quality of the defects mainly include: weld surface cavities, weld internal stomata, weld width unevenly, Welding, and virtual Welding. Factors, which affect the weld quality of main process parameters are: laser output power, spot diameter and absorption rate, relative speed between the beam and workpiece, welding gas flow rate, focus position, and butt joint clearance, etc.
Laser output power laser deep fusion is closely related to laser output power. When the spot diameter of the laser beam is certain, 1.2mm-3.2mm TIG Welding Wire the depth of the deep fusion welding is almost linear with the output power of the laser, and the melting depth increases with the increase of output power. When the laser is welding with steel strip, the actual melting depends on the power of the laser energy to the surface of the welding piece. For welding power is by a light path light reflection and focus of the system, and by laser irradiation to the weldment surface, so the laser output power should measure the actual power of the laser to the welding workpieces. If the output power is too small, it will produce the stoma and melt not enough, which will cause the welding impenetrable.
