High hardness and wear resistance of bucket tooth are required in the face of abrasion and impact. High manganese steel is hard and ductile, making it more suitable for bucket tooth materials. Bucket tooth can wear out and need to be returned to their original size, so that bucket tooth that have been eroded must be coated with a hard material, using a hard facing process. In this study, the hard facing process was carried out in bucket tooth containing 10.4%, 11.60%, 12.70%, 13.60%, and 14.60% men (manganese) elements, using hard facing electrodes of the AWS A5.13 (JIS Z 3251). Hard facing process was using SMAW welding with an average heat input of 1087.43 J/mm. The hard facing process shown that the hardness of weld metal was always lower than of HAZ (Heat Affected Zone) and base metal. The hardness of the weld metal was almost the same for all types of the bucket tooth, which was about 233.478 HVN.

Acidic Corrosion Behavior of Slag-free Self-shielded Flux-cored Arc Welding Overlay

et al. 2022

View full text Add to dashboard Cite

The corrosion resistance of slag-free self-shielded flux-cored welding overlays with different ferrotitanium (Fe-Ti) additions in 3.5 wt.% NaCl + 0.01 mol/L HCl acidic solution was investigated. The corrosion occurs in the matrix rather than M 7 (C, B) 3 , M 3 (C, B) and TiC in the microstructure of all the welding overlays. The corrosion resistance of hypereutectic welding overlay is decreased when the Fe-Ti addition is increased from 0 wt.% to 12 wt.%. The corrosion resistance of the welding overlay is the lowest since the overlay is a eutectic structure at the Fe-Ti addition of 12 wt.%. The eutectic structure increases the interface of corrosion reaction, which accelerates the corrosion rate and increases the corrosion current. With the Fe-Ti addition increasing from 12 wt.% to 24 wt.%, the corrosion resistance of the welding overlays with hypoeutectic structure is gradually increased, owing to the increase of the proportion of TiC and chromium content in the matrix.

“…Plasma transferred arc welding (PTAW), and gas tungsten arc welding (GTAW) are among the arc processes that provide these characteristics [1,2]. Other processes, such as flux-cored arc welding (FCAW) and submerged arc welding (SAW), have a high deposition rate, but with a dilution above 30% where the effects of the substrate impair the abrasion resistance [3,4]. Also, shielded metal arc welding (SMAW) is versatile in obtaining consumables but with a low deposition rate and low-quality coating surface finish.…”

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), where wires of different compositions are used simultaneously to deposit hardfacing. Because of the complexity in stabilizing the welding system, the combined effects of welding parameters should be investigated, allowing elaborate prediction models for the geometry and dilution of the deposits. These aspects are crucial for the target application, wear-resistant layers based on Fe-Cr-C composition, requiring a low-level of dilution and bead-geometry quality. Five parameters were chosen to model the deposition: the welding current, welding speed, standoff distance, torch angle, and wire feed pulse frequency. Therefore, using Response Surface Methodology with five factors at five levels to plan the experiments, thirty-two deposition conditions were necessary to model responses. Complete and reduced models were presented for width, reinforcement, penetration, and dilution responses. The reduced models showed a better prediction than the complete ones. The welding parameters" interaction was identified for the reduced models, where the welding current and speed were influential in all responses. Results showed the possibility of obtaining good quality in the beads applying the FCDW-GTAW technique.
