    摘要： A welding apparatus (10) for longitudinally traversing and circumferentially welding within the interior of a tube. A rotating weld tip and gas supplying containing head is mounted on and rotationally driven by a rotor tube (36) extending from the end (90) of a cylindrical housing (12) in which it is mounted. The axially fixed rotor (36) is surrounded by and is driven by a helix drive connection (52,54,56) to a piston (20) . The piston (20) reciprocates in a cylindrical bore (14) within the housing (12) in response to selectively applied fluid pressure acting against a spring bias (26) . A strain gage (72) on the spring (26) controls the fluid pressure by means of valve ("V") whereby reciprocation of the piston (20) rotates the rotor (36) by means of the helical groove (52) and balls (54) . The various parts are hollow to accommodate the neces­sary wire conductors (70,86) and gas flow. A conductive path between the weld tip (32) and outside source of current is supplied through the conductive rotor (36) a slip ring (19) and wires (86) .

    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.

    摘要： 57 A relative weaving motion of a welding torch (12) relative to a weld line (M) is given to a welding torch, by way of composing a weld main path vector (v) for a relative movement of the weld torch along the weld line and a swing vector (W 1 , W 2 ) for a relative movement of the weld torch. And by detecting the amount of electricity corresponding to an arc of the weld torch, the amount of correction is calculated basing upon the deviation between the detected amount and a predetermined reference amount. The direction of the amount of correction is determined basing upon the swing vector. The relative movement of the weld torch relative to the weld line is performed by a vector composed of the weld main path vector, the swing vector, and the correction vector. In other words, the present invention features in that the direction of the amount of correction is definitely determined basing upon the swing vector.

    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.
