CMTCold Metal Transfer CMT welding process: the most advanced type of droplet detachment CMT welding process High-speed, low-heat input, virtually spatter-free welding Wherever adhesive or solder was used before, CMT (Cold Metal Transfer) welding can be used instead. CMT has revolutionized welding...
In the latest celebrity news, celebrity couple Blake Shelton and Gwen Stefani celebrated their recent win at the CMT Music Awards 2020.
Arc plasmaMechanism of heat transferNumerical simulationAn innovative numerical model was established to study the heat transfer mechanism with cold metal transfer plus pulse (CMT+P) composite heat source based on the in situ observation experiments as well as theories of electromagnetic dynamics, fluid...
CMT+P weldingHeat inputPrecipitates pinningMechanical propertiesG115 steel is a prime candidate for key components in ultra-supercritical (USC) power plants. In this study, G115 welded joint of 15mm thickness had been successfully fabricated using Cold metal transfer plus pulse (CMT+P) welding and...
Experiments were carried out with two customized CMT waveforms. In case 1, a waveform with a current pulse in the short-circuit phase was used and in case 2, a similar waveform was used, with the same average power, but with no current pulse in the short-circuit phase. High-speed video...
The effect of the welding wire composition on the solidification process of the molten pool and the microstructure and mechanical properties of 6063 aluminium alloy hybrid synchronous pulse CMT welded joints was studied. The results showed that the thermal conductivity of the molten pool in the ER...
but with no current pulse in the short-circuit phase. High-speed videography and electrical signals analysis revealed a greater striction effect of the metal bridge in case 1. In conclusion, the current waveform manipulation with CMT can not only improve stability but also the geometric aspect ...
During one cycle of arc burning, trends of arc length and diameter of UHF-ACCMT were similar to that of CMT arc. The average arc length of UHF-ACCMT decreased as the pulse current frequency increased from 20 to 60?kHz. An increase in the current frequency decreased the electrical ...
In this paper, the droplet transfer behavior, molten pool flow and weld formation of Al-Mg-Si alloy CMT MIX+Synchropulse welded joint under different excitation currents were studied. The external magnetic field (EMF) can effectively suppress the porosity and macroscopic pore (>200μm), ...
