Publication number: 20130277344Abstract: Disclosed is a robot pre-heat and inter-pass welding device that is capable of pre-heating and welding one or more weld joints using a single robot. Pre-heating and welding models are used to ensure that a desirable pre-heat temperature is maintained on the weld piece at the location of the weld. Infrared temperature sensors are utilized to detect temperature of the weld piece, which are transmitted to a controller, which controls the operation of both the pre-heating and welding. Multiple welds can be performed if additional time is needed for cooling, which reduces the overall time required to perform the welding process.Type: ApplicationFiled: October 15, 2012Publication date: October 24, 2013Inventors: Lance F. Guymon, Jon Kramer, Zachary Bennett, James R. Pring, Steve Carey, Brent Wessel

Publication number: 20130204434Abstract: A method for positioning a welding head or welding torch of a robot welding system over a workpiece sends microwaves as a measuring signal from a transmitter arranged on the welding head to the workpiece. The microwaves reflected on the workpiece are received by at least one receiver arranged on the welding head, and the received microwaves are evaluated by an evaluation module for determining the position of a workpiece edge. The microwaves are sent from at least one transmitter in different positions on the welding head, and the reflected microwaves are received, with a change of polarization, by the at least one receiver, having a polarization plane arranged at an angle to the polarization plane of the transmitter. The position of the edge is determined by the evaluation module at least on the basis of a phase change of the respective microwaves reflected on the different positions.Type: ApplicationFiled: May 11, 2012Publication date: August 8, 2013Applicant: FRONIUS INTERNATIONAL GMBHInventors: Andreas Haderer, Andreas Stelzer

Patent number: 8440934Abstract: To start consumable electrode arc welding, an initial current is supplied to a welding wire after causing the welding wire to contact a base material and retracting the welding wire from the base material. Thereby, an initial arc is generated. The welding wire is retracted continuously for an initial arc lift period Ti with the initial arc maintained. Afterwards, the initial arc is switched to a steady arc. A predetermined weld pool formation period Tp is set after the initial arc lift period Ti. In the weld pool formation period, a weld pool formation current greater than the initial current is supplied with the initial arc maintained and the welding wire is caused to proceed and fed to the base material. In the weld pool formation period, a weld pool is formed by the initial arc without allowing the welding wire to release droplets and contact the base material.Type: GrantFiled: October 14, 2008Date of Patent: May 14, 2013Assignee: Daihen CorporationInventors: Shugo Hirota, Tetsuo Era, Tomoyuki Ueyama
