摘要： PROBLEM TO BE SOLVED: To suppress a welding state from being unstable as automatic correction on constriction detection sensitivity is improperly made when constriction detection control and feed speed variable control for making a welding current constant are both in operation.SOLUTION: In a consumable electrode arc welding control method of performing constriction detection control to achieve welding by reducing a welding current once a constriction of a droplet being short-circuited is detected, generating an arc again, and automatically correcting constriction detection sensitivity, and also performing welding by bringing a feed speed Fw under variable control so that an average value Iav of the welding current becomes equal to a current set value, a variation rate of the feed speed Fw is detected and the automatic correction on the constriction detection sensitivity is inhibited during a feed speed abrupt change period Tcf in which the variation rate of the feed speed is equal to or larger than a reference value. Consequently, a welding state is prevented from being unstable owing to improper automatic correction on the constriction detection sensitivity in the feed speed abrupt change period Tcf.

摘要： PROBLEM TO BE SOLVED: To reduce the occurrence of spatter caused by vibration of a molten pool, in a constriction detection time current control method for quickly reducing a welding current by detecting constriction of a droplet in a short-circuit period.SOLUTION: When detecting the constriction of the droplet, a welding current Iw energized to a short-circuit load is reduced, and is maintained at a low constriction current value Im, and when an arc is regenerated, the welding current Iw is raised up to a high arc current value Ih from the low constriction current value Im by imparting an inclination S to the welding current Iw when a delay period Td passes. This inclination S in a front half part and a rear half par is a value different from in an intermediate part, and is set so that the inclination of the front half part and the rear half part is a value smaller than the inclination of the intermediate part. Thus, transfer to an inclination period Tu from the constriction current Im and transfer to the high arc current Ih from the inclination period Tu become smooth, and the molten pool is not vibrated when arc force is suddenly changed, so that the occurrence of spatter can be reduced.

摘要： PROBLEM TO BE SOLVED: To solve such a problem that, in a control method in which forward feeding and backward feeding of a wire are periodically alternated, and in which a welding output is made low during a period where the feed amount of the wire is small and the welding output is made high during a period where the feed amount of the wire is large, a short circuit state between a welding object and the welding wire is mainly mechanically opened during a period where the feed amount of the wire is small, but opening of a short circuit is not necessarily smoothly conducted, depending on a kind of disturbance, because the wire is fed forward by small and small and further a current is low although the feed amount of the wire is small. SOLUTION: The method for arc welding includes: a step of calculating a variation amount of a welding voltage per unit time for each predetermined sampling period to compare the calculated variation amount with a reference threshold value for detecting a constriction; and a step of determining detection of a constriction when the number of times, at which the variation amount of a welding voltage per unit time continuously exceeds the reference threshold value for detecting a constriction at each predetermined sampling period, reaches a predetermined number of times.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for determining acceptance/rejection of the welding by a capacitor discharge type stud welding machine capable of determining acceptance/rejection of a stud by the stud welding by a method different from a conventional one. SOLUTION: In the method for determining acceptance/rejection of the welding in the capacitor discharge type stud welding machine, the upper and lower limit values of the current or the voltage with which the welding strength is permitted at three time points including the first reference time point at which a stud fore end tip part is melted, the second reference time point at which the arc is expanded outwardly from the stud center and the energy becomes its peak from the first reference time point, and the third reference time point at which a base material and the stud are welded to each other, are respectively determined to the welding condition to define a first determination area, a second determination area, and a third determination area. The current value or the voltage value in each determination area is measured for the actual stud welding, and the acceptance/rejection of the stud welding is determined based on whether or not the result of measurement is within the range from the lower limit to the upper limit of each determination area.

摘要： PROBLEM TO BE SOLVED: To solve the following problem when repeating forward feed and back feed of a wire, switching from forward feed to back feed at short circuit detection to carry out short circuit release, and switching from back feed to forward feed at detection of short circuit release: if an minute short circuit that is likely to be generated right after arc generation and right before short circuit generation is generated, the wire is immediately reversed, and when there is short circuit release, the wire is immediately forwarded, but when forward feed and back feed are switched in a short time as in such a minute short circuit, since an arc length between the wire and a molten pool is not sufficiently secured and the wire is accelerated, a minute short circuit is more likely to be generated, and it is difficult to secure an orderly and stable arc state.SOLUTION: In arc welding of repeatedly carrying out forward feed and back feed of a wire, when a short circuit is detected predetermined times of two or more times within a first predetermined time during forward feed, switching is carried out from forward feed to back feed, and when short circuit release is detected predetermined times of two or more times within a second predetermined time during back feed, wire feed is switched from back feed to forward feed.
摘要翻译：要解决的问题：为了解决重复正向进给和反馈进给时的以下问题，在短路检测中从正向进给切换到反向进给，进行短路释放，并在检测到反馈时切换到正向进给短路释放：如果发生电弧产生后即将发生短路发生之后的短路短路，则线路立即反转，当短路释放时，线路立即转向，但是当正向进给和反向进给在短时间内被切换，因为线和熔池之间的电弧长度不能充分确保并且线被加速，所以更可能产生微小的短路，并且难以确保有序和稳定的电弧状态。解决方案：在反复进行导线向前进给和反馈的电弧焊中，当检测到短路时在正向进给期间的第一预定时间内确定时间为两次或更多次，从正向进给到反向进给切换，并且当在反向进给期间的第二预定时间内检测到预定次数两次或更多次的短路释放时，送丝切换从反向进给到正向进给。
