Abstract

A system (1) and method for making a welder aware of the contact tip-to-work distance (CTWD) during a welding process. One or both of the welding output current and the wire feed speed (WFs) are sampled in real time during the welding process. The actual CTWD is determined in real time based on at least one or both of the sampled welding output current and the wire feed speed. The actual CTWD may be compared in real time to a target CTWD, wherein the target CTWD represents an estimated or desired CTWD for the welding process. A bias parameter can be generated based on the comparison. An indication of the deviation parameter or the actual CTWD may be provided as feedback to the welder performing the welding process, allowing the welder to adjust the actual CTWD to better match the target CTWD during the welding process in real time.

Description

[0001] This US patent application claims priority and benefit to US Provisional Patent Application Serial No. 61 / 812,782 filed April 17, 2013, which is incorporated herein by reference in its entirety. field of invention [0002] The invention relates to a method according to claim 1 , to a welding system according to claim 6 and to a welding power source according to claim 11 . Certain embodiments of the present invention relate to arc welding. More particularly, certain embodiments of the present invention relate to systems and methods for providing contact tip to workpiece distance (CTWD) feedback for augmented reality. technical background [0003] It is important to maintain a consistent desired contact tip to work distance (CTWD) during the welding process. Generally, as CTWD increases, welding current decreases. Too long a CTWD may cause the welding electrode to become too hot and may also waste shielding gas. Additionally, the desired CTWD may be different for dif...
