摘要： In automatic arc welding where a weld torch follows lateral traverses across a groove during travel along the length of said groove means are provided to produce a control signal representative of the difference between the arc current near the end of each of said traverse and the base arc current at the center of said traverse and further means are provided to arrest travel of said torch on each said traverse each time the integral of said difference reaches a reference value.

摘要： Procédé pour le contrôle et la commande de la position, en tre deux bords métalliques, d'un organe de soudage à l'arc ani mé d'un premier mouvement relatif de défilement par rapport auxdits bords et d'un second mouvement d'oscillation trans versal au premier mouvement.
Selon l'invention, le procédé est caractérisé en ce que, avant soudage, on choisit pour chaque couche de soudage l'é paisseur désirée (e), on détermine la distance (D) séparant ledit axe (15) de la surface du matériau de soudage déposé à la pro fondeur donnée, de manière que, en premier lieu la distance (Δ 1) séparant l'extrémité du fil de la couche de soudure déposée, en position de butée l'organe de soudage sur le chanfrein, soit optimale, et en second lieu, pour une variation dans l'amplitude du mouvement oscillatoire, la variation de cette même distance (Δ 1) soit minimale pour une configuration donnée de l'organe de soudage (2), et en ce que l'on corrige au cours du soudage la position angulaire du plan médian d'oscillation (P1) autour dudit axe d'oscillation (15) en cas de dérive angulaire dudit plan.

摘要： A rotary arc-welding method which comprises: directing a nozzle (8) substantially vertically toward a weld zone; feeding a consumable electrode (12) through said nozzle eccentrical to the axis of the nozzle; feeding welding current to the electrode to produce an arc between the tip of the electrode and the weld zone to weld said objects of welding with each other by means of the arc heat; rotating the nozzle to cause a circular movement of the arc corresponding to the eccentricity of the electrode; and, feeding through nozzles (16,16) a shielding gas toward said weld zone to shield the arc and the weld zone from the ambient air; is characterized in that: the diameter of said consumable welding electrode is limited within the range of from 0.8 to 1.2mm; the welding current is limited within the range of from 400 to 800 amperes; and, the number of rotations of said nozzle is limited within the range of from 3,000 to 6,000 r.p.m.

摘要： A floating reference voltage is generated in response to the low frequency components of weld current and is utilized in the control of the width of travel of a welding arc back and forth across a gap to be filled with weld metal. The arc current is integrated during each traverse across the gap and this integral is compared with the floating reference so that as the wall of the gap is approached, the direction Of travel of the arc will be reversed. Provision is made for avoidance of the effects of "dip transfer".

摘要： An arc-welding method, which comprises: arc-welding objects of welding together along the line of a groove formed between said objects of welding by continuously moving a welding electrode along the line of said groove while reciprocating said welding electrode in the width direction of said groove; characterized by: calculating at prescribed time intervals, for each one reciprocation of said welding electrode in the width direction of said groove, deviations (l-lo) of values (I) of one of arc current and arc voltage from a previously set reference value (lo), for each of left-side deviations (L) and right-side deviations (R) relative to the vertical plane which passes through the center of amplitude of said one reciprocation of said welding electrode and is parallel to the line of said groove; calculating at said time intervals, when said welding electrode moves over the left side of said groove relative to said vertical plane, differences (L-R) between said left-side deviations (L) and the immediately preceding right-side deviations (R), to controllably aligning the center of said amplitude of said one reciprocation of said welding electrode with the center of said groove In the width direction thereof at said prescribed time intervals so that said differences (L-R) become null; and, calculating at said prescribed time intervals, when said welding electrode moves over the right saide of said groove relative to said vertical plane, differences (L-R) between said right-side deviations (R) and the immediately preceding left-side deviations (L), to controllably aligning the center of said amplitude of said one reciprocation of said welding electrode with the center of said groove in the width direction thereof at said prescribed time intervals so that said differences (L-R) become null.
