High-Speed Arc Welding Robots Boost Productivity

In Booth B-27056, Yaskawa America Inc. (Miamisburg, OH) will feature their new AR-series six-axis robots designed specifically for arc welding applications that offer optimized acceleration/deceleration control for all robot axes, resulting in overall improved productivity. These high-performance robots are available with 8 kg to 25 kg payload capacity in order to support a wide variety of sensors and torches for welding application flexibility. AR-series robots offer the highest payload, fastest speed and highest wrist allowable moment in their class. Advanced, intuitive programming functions, such as High-Speed Search, maximize weld quality and speed without complicated programming. Preprogrammed welding processes allow users to select materials and weldment properties to automatically control supply settings. A digital interface on the robot programming pendant allows the user to remotely access and manipulate weld settings with all major brands of power supplies.

Each model offers high allowable moment of inertia ratings that provide substantial wrist rigidity and consistent weld quality. Installation is quick and efficient; a single cable is all that is needed to connect the manipulator to the controller, resulting in easy setup and reduced expenses for maintenance and spare parts inventory. The powerful and compact AR700 and AR900 robots are ideal for welding small parts with complicated angles in tight places with an overarm torch. A slim profile design allows close proximity placement of robots for high-density workcells, and a smooth, easy-to-clean surface accommodates use in harsh environments. As an option, the manipulator cable can be connected on the bottom of the robot (as opposed to the side) to avoid wall interference.

The AR1730 robot features a contoured arm design that allows easy access to parts in tight spots and avoids potential interference with fixtures, enabling close proximity placement of robots for high-density workcells. The symmetric wrist profile, with ample range, provides equal torch access to both sides of part. A 50 mm thru-hole for torch cabling, hose and sensor wires reduces cable interference and wear. Likewise, the minimal U-axis cable protrusion and S-axis internal cable management prolongs cable life and maximizes part access. The AR1730 features a patented double-yoke upper arm design that is stronger than other six-axis integrated cable designs, allowing it to provide years of reliable service at an increased payload while maintaining an agile profile. All three models feature easy maintenance, including a data saving feature that permits the robot’s wire harness to be replaced without having to connect it to a battery. All models can be floor, ceiling, or wall-mounted to enhance joint access.

AR-series robots are controlled by the new high-performance YRC1000 controller that is built to a global standard and does not require a transformer for input voltages ranging from 380VAC to 480VAC. The YRC1000 is highly compact (598 mm W x 490 mm H x 427mm D) for reduced space requirements. Its I/O communication speed is improved by as much as 50 percent for improved work. The improved programming pendant design features enhanced ergonomics and is 27 percent lighter weight than the previous generation.
