AI Technical Summary

Benefits of technology

The system ensures consistent and improved weld initiation by preheating the electrode wire, reducing arc energy requirements and enhancing weld quality by maintaining the electrode at a predetermined temperature before welding.

Problems solved by technology

However, the current state of the art does not provide regimes designed to ensure that the electrode is heated prior to initiation of a welding operation.

Abstract

A contact tip assembly with a preheating tip comprises a welding-type power source configured to provide welding-type current to a welding-type circuit, the welding-type circuit comprising a welding-type electrode and a first contact tip of a welding torch; an electrode preheating circuit configured to provide preheating current through a first portion of the electrode via a second contact tip of the welding torch; and a preheat controller to: monitor a voltage drop across a second portion of the electrode; adjust at least one of the welding-type current or the preheating current based on the voltage drop, the second portion of the electrode comprising at least part of the first portion of the electrode; and control the preheating current based on a hydrogen reduction goal and based on stored parameters associated with a type of the electrode, a chemistry of the electrode, or a wire size.

Description

RELATED APPLICATIONS[0001]This patent arises from a continuation of U.S. patent application Ser. No. 15 / 343,992, filed Nov. 4, 2016, entitled “Systems, Methods, and Apparatus to Preheat Welding Wire,” which claims priority to U.S. Provisional Patent Application Ser. No. 62 / 265,712 filed Dec. 10, 2015, entitled “Welding Torch for Resistively Preheating Welding Wire,” and to U.S. Provisional Patent Application Ser. No. 62 / 329,378, filed Apr. 29, 2016, entitled “Welding Torch for Resistively Preheating Welding Wire.” The entireties of U.S. patent application Ser. No. 15 / 343,992, U.S. Provisional Patent Application Ser. No. 62 / 265,712, and U.S. Provisional Patent Application Ser. No. 62 / 329,378 are incorporated herein by reference.BACKGROUND[0002]Welding is a process that has increasingly become ubiquitous in all industries. Welding is, at its core, simply a way of bonding two pieces of metal. A wide range of welding systems and welding control regimes have been implemented for various ...
