Yaskawa AccuFast II laser-based seam finder improves weld quality and reduces cycle times

AccuFast™ II, an economical laser-based seam finder for Yaskawa Motoman’s arc welding robot line, features improved sensor capabilities. The improved sensor offers increased performance by providing more reliable and repeatable feedback to the robot controller regarding part position. It also provides readings on a variety of materials and at angles of measurement that were not formerly possible.

AccuFast II utilizes a non-contact, commercial point laser instead of “touch” sensing with the weld wire, which allows the robot to quickly and accurately locate welding seams. It greatly reduces cycle times not only by removing the need to cut the weld wire, but it also provides faster search speeds by eliminating wire deflection.

The AccuFast II laser seam finder is compact, mounted in-line with the welding torch and is compatible with Yaskawa Motoman’s industry-leading thru-arm torch design robots. The sensor uses the same input and output signals as traditional touch sense, allowing it to be easily retrofitted into existing robot installations.

Macro job routines simplify programming by providing a single instruction in the robot job for detecting a seam or feature. The laser sensor is housed in an enclosure with a pneumatic shutter to protect it from the harsh welding environment. An optional laser target aids in maintaining the sensor TCP and can adjust points if the sensor is serviced.

In addition to AccuFast II, Yaskawa Motoman offers sensing technologies, ranging from cost-effective thru-wire touch sensors to cutting-edge laser and vision systems.

Varispeed Appointed as Yaskawa’s Channel Partner
Yaskawa Southern Africa have also announced that with effect July 2017, Varispeed SA, a division of the Hudaco group have been appointed as Yaskawa’s Channel Partner for its full product range of Yaskawa Servo Drives, Motors, Controllers as well as its VIPA, PLC, HMI and I/O products.

Varispeed has been closely connected to Yaskawa for more than 20 years as a Channel partner responsible for the sale of Yaskawa’s VSD products and will now expand their offering to include Yaskawa’s full portfolio of drives, motion and controls.

Saying this Varispeed is enlarging their Yaskawa portfolio with Servo, PLC, HMI and IO offering.

Varispeed will assume and take full sales, service, repair and training responsibility for this product range in South and Southern Africa, and as such, through their national sales and service network, provide a “one-stop” world class drives, motion, control source of supply and technology.
