Abstract: Reliable welding quality monitoring (WQM) is a long-standing challenge for climbing gas tungsten arc welding (GTAW) due to the inherent instability and complexity of the weld pool during ...

In terms of welding techniques, the gas tungsten arc welding/tungsten inert gas (GTAW/TIG) process epitomizes a skill set driven by a need for practitioners to constantly develop their skills in ...

The hardfacing deposition with the GTAW process is widely studied with the addition of metallic powder or solid wire. This study introduces an original method, flux-cored-double-wire GTAW (FCDW-GTAW), ...

This work investigates the mechanical properties of a weld produced by gas tungsten arc welding (GTAW) of a pipe of 12%Cr supermartensitic stainless steel with 625 nickel alloy as filler metal. The ...

Autogenous orbital gas tungsten arc welding (GTAW) is a controlled, precise welding technique developed to reduce the chance of operator error and improve weld ...

Consider an automated pipe welding application. Most likely you’d use a wire-fed gas tungsten arc welding (GTAW) process for the root pass, then stop and switch to a flux-cored arc welding (FCAW) or ...

Miller Electric Mfg. Co. has introduced two GTAW/SMAW welding power sources that deliver up to 800 amps for applications such as pipe and tube fabrication, precision fabrication, pressure vessel ...
