摘要： A device and a method for welding, which enables high quality welding to be applied to surface-treated metals such as galvanized steel plates while keeping the plates in close contact with each other. At the time of welding, auxiliary gas with which oxygen gas is mixed is jetted to a working point (9) of the lapped surface-treated metals (3a, 3b) such as galvanized steel plates from a space (7) surrounding an electrode (1) through a nozzle (8). When the surface-treated metals (3a, 3b) such as galvanized steel plates are welded in the atmosphere of auxiliary gas with which oxygen gas is mixed, the surface substance such as zinc reacts with oxygen to produce a solid oxide such as zinc oxide or zinc peroxide without generating gas such as zinc vapor between the lapped surface-treated metals (3a, 3b). Therefore, no blowhole, that blows off molten steel plates is generated and high quality welding is possible.

摘要： A method of working with a laser beam to cut a workpiece according to a working program comprising consecutive move instructions and laser beam output instructions. An angle of a passage along which the workpiece is worked is computed with the move instruction under execution and the subsequent one (S2, S3) read. The angle of the passage thus computed is compared with a preset angle (S4), and, when the angle of the passage for working is sharper than the preset one, move for working based on the move instruction under execution is decelerated and stopped (S5). At this time, a laser beam output instruction is shifted from cutting work conditions to drilling work conditions for performing drilling work. At the end of drilling work, move for working is again started on the basis of the subsequent move instruction and the laser beam output instruction at the time of re-start of move for working is changed from drilling work conditions to cutting work conditions according to move for working. In this way, a part of workpiece in acute angle can be worked sharply.

摘要： A laser piercing method which reduces a machining time prevents thermal runaway and minimizes variance of a machining time. In this method, piercing is started at an initial pulse frequency Po and an initial pulse duty ratio of Qo, and then the pulse frequency and the pulse duty are increased by increments of P and Q, respectively, at predetermined time intervals of T. After a set number of increments or a predetermined time from the start of machining, the increase is stopped and machining is continued till the completion of machining. Accordingly, the machining time can be reduced to 1/3 to 1/5 of the machining time of the prior art, and thermal runaway can be prevented. Variance of the machining time can be reduced, as well.

摘要： A system, in which the length of propagation path from a laser oscillator (6) to a condensing means (a6) of a processing head (5) in a laser processing machine (1), i.e., an optical path length can be desirably fixed to a preset value. In the multi-axis control type laser processing machine (1) wherein the processing head (5) is drivably controlled in directions of plurality of axes (X, Y, Z axes), respectively, with respect to a main body of the processing machine by a head driving means, and an optical path length extending-shrinking mechanism for extending or shrinking the optical path length from the laser oscillator (6) to the condensing means (a6) independently of the movement of the processing head (5) is inserted into the intermediate portion of the propagation path. In the optical path length extending-shrinking mechanism, there are combined with each other an optical path length control means and an optical path length setting means. The extending-shrinking mechanism is provided with an axis movement value calculating means for calculating a total sum of values of the movement of the respective axes for driving the processing head (5), and a value of 1/2 of the value calculated by the axis movement value calculating means is input to the optical path length control means, to thereby drive the optical path length extending-shinking mechanism and offset a change in the optical path length due to the movement of the processing head.

摘要： A method of controlling piercing of a laser machining apparatus to obtain good machining condition at the time of starting laser beam irradiation and reduce the piercing time. A peak value (S), a frequency (P) and a duty ratio (Q) which are the output parameters of a laser beam are maintained at minimum values (Ss, Ps, Qs) until a time (ta) lapses from the start of the laser beam irradiation. These parameters linearly increase during the period from the time (ta) to a time (tb) and are then maintained at maximum values (Se, Pe, Qe) during the period from the time (tb) to a time (tc). Thus, the laser beam output is maintained small at the start of irradiation (time 0 to ta) to prevent violent sputtering and to smoothly start the piercing. After the piercing has proceeded to some extent where sputting no more takes place (time ta and on), the output is continuously increased to perform the piercing smoothly and in short periods of time.
摘要翻译：控制激光加工装置的穿孔的方法，以便在开始激光束照射时获得良好的加工条件并减少刺穿时间。作为激光束的输出参数的峰值（S），频率（P）和占空比（Q）保持为最小值（Ss，Ps，Qs），直到从起始点（ta）经过时间（ta）的激光束照射。这些参数在从时间（ta）到时间（tb）的时间段内线性地增加，并且在从时间（tb）到时间（tc）的时间段期间被保持在最大值（Se，Pe，Qe）。因此，在照射开始时（时间0〜ta），激光束输出保持较小，以防止剧烈的溅射并平滑地开始穿孔。穿刺过程进行到一定程度，不再发生爆裂（时间和时间），输出不断增加，在短时间内顺利进行穿孔。

摘要： A laser machining apparatus adapted to apply a laser beam to a work and cut the same. The cutting of a work of a nonferrous metal is done efficiently and stably, and the cutting of even a work of a large thickness is also done. In a point A, a boring process is carried out under a machining condition A to form an arcuate portion (31). The machining condition is then switched to B, and an expansion treatment is carried out to form an expanded bore (32) in an extended form of the original arcuate portion (31). When the expansion treatment has completed in the position B, the stand-off (distance between the front end of a machining nozzle and the surface of the work) is set to a lowest possible level, and the machining condition is switched to C, under which a cutting process is started. Therefore, the cutting process is carried out in substantially the same manner as in a process in which the cutting of a work is started directly from the outer side of an end portion thereof. During the cutting process, the pressure of an assist gas is set high, and the stand-off small, so that the dross scattering effect by the assist gas is displayed more remarkably. Accordingly, a cutting process can be carried out efficiently and stably.

摘要： A linear motor (20) is constituted of an armature coil incorporated in a movable slider (24) and a fixed magnet (22). The slider (24) and the driven body (14) of a laser beam machine united with the slider (24) are driven linearly. When the slider (24) and driven body (14) are driven, the magnetic attracting force acting between the slider and the magnet (22) is offset by the magnetic attracting force between another magnet (32) for compensation on the top of the driven body (14) and a stationary magnet (34) above the magnet (32). Therefore, the frictional resistances which act on linear guiding means (16a and 16b) during the movement of the driven body (14) are reduced.

摘要： A laser machining apparatus for boring a round hole in a work in accordance with a machining program, wherein a tool starts at a point P1, passes through a point P2 (a through-hole formed in advance in the work) and reaches a point P3 on a cutting circle (40). This path P2 to P3 is not a regular arc and its radius of curvature is the maximum at the start point (point P2), and progressively decreases until it becomes closest to the radius of the cutting circle (40) at the end point P3. Therefore, the variations in acceleration at the points P2 and P3 of the path P1-P2-P3 are small.
