Situation 

One of the core co鄉影mponents of new e國但nergy vehicles is drive motor, in or高吃der to achieve the new energy們朋 vehicles in batches of production, imp金窗rove the motor s裡體tator’s production efficiency and qual信機ity becomes very什女 necessary. 

General solution 

The stator of motor is made by sta好又cking silicon steel shee說鐘ts. Generally, welding is used to w草資eld several welds alon船員g the axial direction of th時鐘e stack of stator, so that the silicon白相 steel sheets ca劇站n be firmly connected toget少又her. This will not哥了 only make the process 影員simple, but also increases the insu匠遠lation resistance between the stator一又 silicon steel sheets and increa路土ses the effective permeance靜作 cross section, thus improving開議 the quality of the motor.

Traditional manual arc weldin也和g due to small h學日eat, large heat affected對文 zone, welds are not smo做文oth and can't be automat票你ed, low efficiency and other factors船你, now rarely used. TI做姐G welding arc stabil船文ity because of the arc, g窗亮ood elasticity, without filling the met長得al, welding parameters easy to co北金ntrol, weld smooth and clean, no splash暗些 and other factors, wide資件ly used. However, due湖自 to silicon steel sheet with high si黑機licon content, so it c好紙onduces poor weldab學火ility， easy to cra東呢ck after welding a時現nd hard to weld.

So in recent years th讀身e use of laser welding has become 生快a very promisin快美g alternative.

Laser welding solutio你大ns 

Laser welding is the l靜視aser output of high麗一 power density of t們費he laser beam through the focus, so t笑來hat the spot is s行東mall, energy concentration, hi北道gh density, heating effi區人ciency, then the weldin舞民g metal deformatio件機n is small. Because 藍刀silicon steel is a silicon conte歌事nt higher, lower carbon content of f校木errosilicon all子村oy, its low thermal conduct照睡ivity, thermal sensitivity, i低新s conducive to 答器rapid heating with a laser beam飛她 melting, it can form a good 們身connection weld.

Zhejiang Jinggong Roboti短章cs&Intelligent Equipment Co., Ltd朋兵. is a professional manufacturer of hi錯笑gh-power laser applicatio我土ns. It adopts imported high-power laser市科 to carry the welding head and adopts 北地Siemens 840D CNC shaft t月購o realize the one-time w數銀elding of the whole stator.

Compared with the traditiona工藍l argon arc weldin玩報g, the efficiency is問又 improved by 5-8 ti場子mes, the weld qu員如ality is close to perfect and t技公he heat affected zone is very smal就農l. The entire automati校書c laser welding unit can real舊子ly achieve the stator chip a學鐘ssembly, compression, laser唱要 welding and automa去業tic cutting the entire長醫 process automaticall志紅y. Greatly improving 朋作the new energy automotive motor stator兒玩 production efficiency and quali銀計ty, and ultimately for the r市銀ealization of new energy vehicles 務了in batches, high-qual美就ity production to provide the perfect 化月solution.
