currently high can welding by main/primary field/area is: ① high can equipment large type 化—功 rate large type and can processing parts （乃至 parts formed ） large type 化. ② new type equipment made, 诸如, 脉冲工 as methods and short long light device and other. ③ equipment can and processing flexible 化. ④束流 quality improve/increase and diagnosis. ⑤束流, parts, process versus function mechanism research. ⑥束流 composite/compounding. ⑦ new material welding. ⑧ application areas expand 展. 1, light welding most new 进展 1.1 new type light device ——（1）直流 sheet/plate strip/profile 式（DC Slab）CO2激 light device, （2） 二极 tube/pipe YAG激 light device, （3）CO激 light device, （4） semi 导体激 light device, （5）准 separation light device. 1.2 激 light device rate large type 化, methods and high quality light 束模式 以 USA PRC company is 例, year front, used for CO2激 light device rate main/primary is 1500~2000W, 而近期 主导 product is 4000~6000W, 6000W can 切割 不锈钢 thick degree, carbon thick degree separation is 35 mm and 40 mm. 1.3 equipment can and processing flexible especially is for YAG激 light, due to can use light 纤传输, to processing belt/tape large 方便. its main features is: ①一 machine more use. ② using/adopting 一台激 light machine can more 工位（ can 达6 ） processing. ③ light long degree most long can 达60m. ④开放式 control 接口. ⑤ tool has 远距离 diagnosis function. 1.4 束流 composite/compounding most main/primary is light － electrical composite/compounding. deep welding 时, upper generate and other 离子体, composite/compounding processing 时, light generate and other 离子体 has electrical stability; composite/compounding processing can improve/increase processing efficiency; can improve/increase welding property 差 材 material aluminum alloy, di versus and other welding property; can increase welding stability property and can property; usually, light add filament is very 敏感, through and electrical composite/compounding, 则变 容 easy can 靠. light － electrical composite/compounding main/primary is light and TIG, Plasma以 and GMA. through light and electrical versus effect/influence, can 克服每一 types methods 自身 不足, generate good composite/compounding 效应. GMA cost low, use filament, suitable property strong/high, disadvantages is deep shallow, speed low, parts hot large. light can formed deep narrow 焊缝, speed high, hot low, investment high, for parts made degree requirements high, for aluminum and other material property 差. Laser-GMA composite/compounding performance in: electrical increase for 间隙 桥接 property, its causes has 二: is filling filament, is electrical add hot scope/range relatively wide; electrical rate 决定焊缝顶部 wide degree; light generate and other 离子体 decrease small electrical 弧引燃 and retardant force, make electrical more stability; light rate 决定 焊缝 deep degree; more 进一步讲, composite/compounding efficiency increase and welding property reinforcement. from can amount 观点看, light electrical composite/compounding for welding efficiency improve/increase separation significantly. this main/primary 基于两 types 效应, is relatively high can amount density relatively high welding speed degree; is hot versus function add 效应. GMA, light add filament and light electrical composite/compounding types methods welding can amount, 焊缝断面以 and can amount utilizing rate comparison. Laser-TIG Hybrid can significantly increase speed, is TIG welding 时 2倍; 钨极烧 loss large large decrease small, lifespan increase; 坡口夹角亦 decrease small 焊缝面积 and light versus 近. large 学弗朗 and light technology 学院研 made types light di composite/compounding welding, and light mono composite/compounding versus ratio, welding speed degree can increase 约1/3, can amount decrease small 25%. UK Conventry large 学现代连接 in has Laser-plasma composite/compounding welding 报导. its advantages is: improve/increase welding speed degree and deep; due to electrical add hot, metal temperature degree rise high, reduce metal for light rate, increase for light can absorption. in small rate CO2激 light experiment/testing upper, also need in 12 000W CO2 激 light and light 纤传输 2kW YAG激 light device upper 进行, is machine 人进行PALW打基础. 1.5 aluminum alloy light welding aluminum alloy due to ratio strong/high degree high, resistant property good 而 以广泛 application. CO2激 light welding aluminum alloy difficult main/primary in high rate and thermally conductive property good, difficult to temperature degree, difficult 于诱导 small 孔 形 formed （ especially is for Mg content comparison small 时）以 and easy generate gas 孔. improve/increase absorption rate measures remove surface chemical modified （如 cationic oxidation ）, surface plating, surface coating and other outer, has use light －TIG, light －MIG 报道, its in MIG－DC electrode position methods due to surface function strong/high and add filament alloy function is good. most 近, ratio L Cretteur and France S Marya for 6061 aluminum alloy mixed combined gas and agent CO2激 light 焊. in to experiment/testing conditions lower table/sheet 明: 70%He+30%Ar, gas direction and welding direction versus 反时效果 is good; for welding 时焊缝背面容 easy generate lower defect, using/adopting 75% LiF+25%LiCl agent, to remove oxidation, improvement metal and 背面母材 接 combined, make 背面焊缝 tool has " upper 翘"效应, in relatively wide parameters inner formed 规整 焊道. for 6061 aluminum alloy welding table/sheet 明, strong/high degree can to 母材 90%. 1.6 激 light 熔覆 激 light and its it surface modified methods versus ratio, add hot speed degree fast, hot less, deformation small; combined strong/high degree high; dilute rate low; modified thick degree can control, property good, can property good, production efficiency high. light remove used for product outer, 英, and other already used for aviation machine machine Ni基涡轮叶 sheet/slice heat resistant, wear resistant 层 熔覆 and 修复. 2, electronics welding and and other 离子弧 welding most new 进展 国 outer electronics welding development can is: ultra-high can density plant/unit made, equipment can flexible 化, electronics features diagnosis, and material function mechanism research and non true electronics equipment and process research and other. in Japan, accelerated electrical pressure 600kV, rate 300kW ultra-high pressure electronics machine already 问世, one-time can 焊200 mm 不锈钢, deep wide ratio 达70: 1. day, 俄, 德开展 di and filament electronics technology research. in for large thick degree sheet/plate one-time welding upper, through 第二次填 filament 弥补顶部 lower or defect; Japan using/adopting di achieve thin sheet/plate ultra-high speed welding, 反面无飞溅, formed good.
