Laser beam welding receives the application in stainless steel thin plate

The ultrathin stainless steel of 2min piece, the material such as the belt reachs daily expense containers esp. for use in the house in medical apparatus and instruments, industrial product medium use is more and more extensive. Of material of ultrathin to these stainless steel solder, also raised more slashing requirement. Because the ply of material is too thin. Soldering difficulty increases significantly, current, use resistance welding method normally (basically have spot welding and seam welding) . But because hot input is big when resistance welding. Bring about material generation very easily to be out of shape. Be used in what parts of an apparatus can affect below a lot of circumstances and of the exterior beautiful. Although solder of arc of tungsten pole argon is to solder the appropriate method of stainless steel, but should solder method to ply ＜ 0.

The stainless steel of 2inm piece difficulty is very great. Solder to be compared with the tradition, seam welding of small-power pulse laser has power density concentration of tall, energy, hot input small, welding line is narrow and be out of shape small wait for an advantage, and very small facula can be obtained after stimulating focusing of beam of light, can exact location, these characteristics make laser seam welding is compared other solder method more agree with of small size workpiece solder. Solder to the laser of material of ultrathin stainless steel, because data is very weak, very easy vaporization is perforative, want to get successive, without burn the welding line that wear. The key is the accurate control to parameter. The main parameter that affects laser beam welding to receive quality has solder frequency of width of electric current, pulse, pulse, its affect the effect to basically be as follows: (The 1) accretion as electric current, the width of welding line increases, solder the process appears gradually splatter, phenomenon of occurrence oxidation of welding line surface, have coarse feeling. (2) follows the accretion of pulse width, the width of welding line also is in increase. The effect impact that the change with broad arteries and veins exceeds laminose laser beam welding to receive to stainless steel is very striking. Of pulse width tiny increase, bring about sample possibly to be mixed to burn by oxidation wear. (3) follows the addition of pulse frequency, solder nods jackknife rate to increase, welding line width increases first. Hind keep basically changeless. Observation falls in microscope, welding line is smoother and smoother and beautiful. But when pulse frequency raises fixed cost, solder the process splatters serious, welding line becomes coarse, and the fluctuation surface of weldment appears oxidize phenomenon. (The laser that 4) ultrathin plank expects solders to be used aptly leaving anxious, be in identical below the case that leaves anxious amount, the welding line face that getting from anxious laser beam welding wants from Jiao Shi than losing smooth and beautiful.
