Aspects of the technology employ real-time monitoring and feedback for a printed circuit board fabrication system. An x-ray simulator can be used to aid in understanding metallurgical phase transformations in real time to ensure acceptable and reliable solder connections. This includes real-time data gathering and evaluation of solder-related printed circuit board data, including peak temperature, time above liquidus (TAL), ramp up and ramp down rates. Such information is used to identify the exact melting point and view specific soldering behavior in order to achieve an optimized soldering solution. This approach can provide effective solder joint analysis, which can reduce the likelihood of failure of a circuit board intended to operate in extreme environments for an extended period of time, such as the stratosphere.

The present invention relates to an apparatus for preventing welding distortion and a method for welding a pipe and a flange using same, the apparatus being capable of effectively reducing welding distortion of a flange, which occurs during welding with a pipe and improving economic efficiency and productivity. The apparatus for preventing the welding distortion comprises: at least one counterweight which is arranged to be in contact with one side of a flange that is to be welded to a pipe, and has a hollow portion therein; and a fastening tool which fixes the counterweight to the flange, wherein the hollow portion of the counterweight may accommodate a refrigerant.

Methods for determining the quality of a weld of a workpiece welded by laser-beam welding, wherein at least a partial region of a molten pool and/or of a surrounding area of the molten pool is observed by means of a measuring system during the laser-beam welding and the quality of the weld of the welded workpiece is determined on the basis of the observation result. At least one characteristic value that correlates with molten pool oscillation of the molten pool is observed during the laser-beam welding and a measure of an amplitude of the molten pool oscillation and/or a measure of a frequency of the molten pool oscillation is determined from the observed time curve of the characteristic value. A probability and/or a frequency for the occurrence of hot cracks at the weld of the workpiece is inferred.

The present disclosure discloses a button cell, and a method for welding electrode tabs to a pole shell of the button cell. The button cell includes the pole shell and an electric core. The pole shell consists of an anode shell and a cathode shell. The button cell further comprises at least one metal sheet. A cathode tab and/or an anode tab of the electric core is/are welded to the metal sheet, and the metal sheet is then welded to the cathode shell and/or the anode shell. The button cell manufactured by the invention has a complete surface, and can avoid phenomena such as electrolyte leakage and surface bulging caused by the rupture of the polar shell.

An inspection system is configured to inspect the condition of a braze joint formed within a structure, wherein the braze joint is formed from a braze filler material having a tracer material disposed therein. The inspection system includes an energy source for directing energy towards the structure, an energy detector for detecting information regarding the structure following interaction with the energy directed from the energy source, and a data analysis system for analyzing the information detected by the energy detector. The data analysis system is configured to distinguish the tracer material from the remaining materials forming the structure in order to determine a suitability of the braze joint.

Embodiments of systems and methods for supporting predictive and preventative maintenance are disclosed. One embodiment includes manufacturing cells within a manufacturing environment, where each manufacturing cell includes a cell controller and welding equipment, cutting equipment, and/or additive manufacturing equipment. A communication network supports data communications between a central controller and the cell controller of each of the manufacturing cells. The central controller collects cell data from the cell controller of each of the manufacturing cells, via the communication network. The cell data is related to the operation, performance, and/or servicing of a same component type of each of the manufacturing cells to form a set of aggregated cell data for the component type. The central controller also analyzes the set of aggregated cell data to generate a predictive model related to future maintenance of the component type.

A welding block for a welding system secures together first and second components of a workpiece for a motor vehicle to reduce distortion of the first and second components during a welding process. The welding block includes a jig mechanism that has a proximal surface for receiving a load from an arm of the welding system. The jig mechanism further includes a distal surface for engaging the first component and securing the first and second components to one another during the welding process. The jig mechanism defines a passage, such that heat flows from the distal surface to a coolant flowing through the passage. The welding block further includes a sensor coupled to the jig mechanism for detecting a measured variable associated with at least one of the first and second components.

A system for generating a G-code for controlling an operation of a laser-cutting machine to cut parts from a sheet of material, upon receiving cutting data specifying a cutting order of parts and a cutting order of edges of each part, tests the parts for potential distortions and generates a G-code to avoid the potential distortion. For testing a current part, the system detects a potential distortion when the final edge of the current part is adjacent to an edge of a previously cut part scheduled for cutting before the current part according to the cutting order of parts. The system modifies the cutting order to select the modified cutting order for which the final edge is not adjacent to any edge of any previously cut part.

The invention relates to a method for monitoring a joining seam, in particular during joining by means of a laser beam, wherein in the processing direction before a processing point a joining site is measured in order to detect the position and geometry thereof, at least one position of a joining seam is determined from the position of the joining point, and in the processing direction after the processing point the joining seam is measured in order to detect the geometry thereof at the determined position. The invention further relates to a device for carrying out said method and to a laser processing head equipped with such a device.

A method for limiting fitting distortion when welding a fitting to an in-service pipeline—where the fitting includes a thick, longitudinally extending, seam located between fitting halves—involves welding, on each side of the fitting, a middle third section of the seam in a pyramid-like fashion using an inward progression starting from an end of the middle third section along a profile of a seam bevel, and welding outer third sections of the seam using an outward progression from an end adjacent to the middle third section along a profile of the seam bevel. The welding of each of the three sections per side includes a temper bead welding technique of at least two layers to provide stress relief in lieu of traditional post weld heat treatment.
