摘要： A modular two-part welding and processing platform is described. A cart section is capable of rotating around objects such as pipes and cylinders, or of linear travel along plates or the like. This cart section reversibly couples to a processing section supplied for instance with welding apparatus, painting apparatus, cleaning means, analysis means or the like. By means of this two-part device, work pieces can be cleaned, welded, and inspected quickly and accurately. Special marks may be provided on the work piece which in conjunction with sensors and motoring means on the cart, allow for precise positioning of the process head with respect to the work.

摘要： A method of computing optimal beam numbers of a phased-array ultrasonic weld inspection arrangement. The arrangement is for inspecting a weld that is within an area of interest that has a known dimension and with the inspection arrangement being at a known offset distance from the weld. The selection is such that operation of the at least one element provides sufficient information data for weld analysis. The elements extend along an ultrasonic transmission wedge of the arrangement that supports the extent of the elements at a wedge angle relative to the welded material. The method includes utilizing the dimension of the weld area of interest and dimension of offset of the inspection arrangement from the weld within calculation that yields the selection of the at least one element.

摘要： The method of optimising resistance welding parameters comprises, based on a given welding current pulse (I sold ) applied to metal elements to be welded providing a weld that is considered to be correct in one spot of a spot welding sequence, performing in each subsequent spot of the sequence: applying a first current pulse (I FVP ) obtained by voltage profile monitoring and a second current pulse coinciding with said given pulse (I sold ); repeating the two pulses, adjusting in each repetition the first pulse value until reaching a value equivalent to the energy provided by said given pulse (I sold ); and applying to the subsequent welds of the sequence, a series of current pulses with an intensity value corresponding to the welding current pulse of said final adjustment.

摘要： There are provided an optical non-destructive inspection apparatus and an optical non-destructive inspection method, which can inspect a measurement object such as a wire bonding portion in a broad measurable temperature range in a short time, with high reliability. The apparatus includes a focusing-collimating unit (10), a heating laser beam source (21), a heating laser beam guide unit, an infrared detector (33), an emitted-infrared guide unit, first and second correcting laser beam sources (22, 23), first and second correcting laser beam guide units, first and second correcting laser detectors (31, 32), first and second reflected laser beam guide units, and a control unit (50). The control unit (50) controls the heating laser beam source (21) and the first and second correcting laser beam sources (22, 23), measures a temperature rise characteristic that is a temperature rise state of a measurement spot (SP) based on a heating time, on the basis of a detection signal from the infrared detector (33) and detection signals from the first and second correcting laser detectors (31, 32), and determines a state of a measurement object (bonding structure (97)) based on the measured temperature rise characteristic.

摘要： Maximum allowable load values of a welded portion in respective fracture modes of a load fracture, a moment fracture, and a nugget interior fracture are found based on at least one of a sheet thickness t, a tensile strength TS, an elongation El, and a chemical composition of a nugget portion in each of spot-welded steel sheets, a nugget diameter d of a welded portion, an effective width B of the welded portion determined by a distance between adjacent welded portions, edges or ridge lines, and a sectional height H. Then, according to these fracture modes, an allowable load value at every moment after the maximum allowable load value of the welded portion is reached is found, and a displacement or a time at which the allowable load value becomes 0, that is, at which a complete fracture occurs is found, thereby finding a fracture limit.
