Low Efficiency

In general, flange is fixedly connected with tubular parts or cylindrical parts through manual welding. For high labor intensity, low efficiency and poor welding quality of manual welding, a special automatic welding machine for adaptor flange of tubular parts or cylindrical parts is developed. It mainly consists of machine frame, rotary worktable, swing arm, sliding shelf, wire feeder, drive unit, control cabinet and welding torch. The welding machine has two rotary worktables controlled by PLC. With the advantages of simple structure, low production cost, high welding speed, good welding quality and low labor intensity, it is particularly suitable for small and medium sized enterprises

For the continuous welding problem of multi-T-tube radiators intersecting line, a new type of two-welding torch automatic welding machine is designed. The design scheme of the welding machine is described, and its main mechanisms are designed. Using three-dimensional software, its model is built. Motion simulation and interference checking are carried out based on interpolation. The fact welding test shows: the intersecting line is accurately welded and the production efficiency and welding quality is enhanced.

Welding System

This article illustrates that factories and machine shops use automated controls, sensors, and continuous electric arcs to make faster welds better. Welding system manufacturers, such as Lincoln Electric Co. of Cleveland, work with robot manufacturers, including ABB, to integrate their products and tailor automated welding systems that make faster precision welds. At the same time, instrumentation companies, such as LMI Selcom of Gothenburg, Sweden, have developed sensors to improve the precision of automated welding systems even further in high-volume applications. LMI Selcom Robotic Guidance of Gothenburg, Sweden, developed its SeamFinder laser measurement systems to improve the welding quality and cycle times of robotic. A key component to the Power MIG 200 is its Diamond Core technology, an internal assembly that provides a constant electrical current to the welding torch. A Michigan-based welding company taking advantage of the Power MIG 200’s smooth arc is Midstate Utility in White Cloud. The company fabricates machinery used to install telephone cable. Midstate Utility has been using the Lincoln unit since October of 2000.

Purpose This pilot study explored the effectiveness of an early storybook reading (ESR) intervention for parents with babies with hearing loss (HL) for improving (a) parents' book selection skills, (b) parent–child eye contact, and (c) parent–child turn-taking. Advancing research into ESR, this study examined whether the benefits from an ESR intervention reported for babies without HL were also observed in babies with HL. Method Four mother–baby dyads participated in a multiple baseline single-case experimental design across behaviors. Treatment effects for parents' book selection skills, parent–child eye contact, and parent–child turn-taking were examined using visual analysis and Tau-U analysis. Results Statistically significant increases, with large to very large effect sizes, were observed for all 4 participants for parent–child eye contact and parent–child turn-taking. Limited improvements with ceiling effects were observed for parents' book selection skills. Conclusion The findings provide preliminary evidence for the effectiveness of an ESR intervention for babies with HL for promoting parent–child interactions through eye contact and turn-taking.
