“…GMAW brazing has been used in short circuit transfer mode due to the low heat input during fusion as compared with spray and globular transfer modes. The automotive industry has focused especially on solving burn-off coated AHSS materials [9]. However, due to the better arc control of pulsed arc, GMAW-P has received more attention in virtue of its benefits [10].…”

Joints of complex phase 780 (CP-780) advanced high strength steel (AHSS) were carried out by using an ER-CuAl-A2 filler metal for the gas metal arc welding pulsed brazing (GMAW-P- brazing) process and the ER-80S-D2 for the GMAW-P process employing two levels of heat input. The phases in the weld bead and HAZ were analyzed, and the evaporation of zinc by means of scanning electron microscopy (SEM) was also monitored. The mechanical properties of the welded joints were evaluated by tension, microhardness and vertical impact tests. It was found that there was greater surface Zn evaporation in the joints welded with the GMAW-P process as compared to the GMAW-P-brazing process. The best results in tensile strength were observed in the joints welded with GMAW-P-brazing process, which increased by ~68% with respect to those of the GMAW-P. This behavior can be attributed to the formation of an intermetallic complex compound Cu-Al-Fe in the fusion line.

“…Gas metal arc (GMA) process is the most popular metal joining method using arc with a shielding gas due to its various advantages such as good weld penetration, reasonable brazing speed, less slag, etc., [11][12][13]. However, GMA brazing requires the optimization of various operating parameters, such as arc speed, arc current, filler feeding rate, shielding gas rate, etc.…”

Arc brazing of zinc-coated steel (EG, Electro-galvanized steel) using Cu-3 wt%Si filler metal was performed. The influence of arc current and brazing speed on the bonding properties of the joint, such as bead characteristics, arc penetration, joint hardness, and tensile shear strength were evaluated. The microstructural characteristics of the joint were examined by scanning electron microscopy (SEM) and the compositional information was revealed by energy dispersive spectroscopy (EDS). The throat thickness varies inversely with the brazing speed. The EG joint shows the formation of Fe2Si phases, which result in higher microhardness than the base metal. The tensile samples were fractured in base metal, while minor bead cracks developed in the samples brazed at 80 cm/min-80 A, 60 cm/min-70 A, 70 cm/min-70 A.

“…It has been demonstrated that in non-load carrying joints such softening might result in the joint area being the weakest component of a structure [1]. GMAB (or MIG brazing) is a well-known process in industries where thin-walled structures are constructed using galvanized steel plates [2][3][4][5]. By using GMAB instead of conventional fusion welding, the beneficial effect of the galvanized layer, e.g.…”

With the aim of maximizing energy efficiency, the use of low-alloyed ultra-high strength steels (UHSS) has greatly increased in vehicles and other transport applications in recent decades. Using UHSS, equivalent ultimate load capacity can be achieved with less material than when using conventional structural steels. Along with increased static load, structures commonly made of UHSS are often subjected to high cyclic load, and good fatigue strength is thus demanded. In this study, the fatigue strength was obtained for gas metal arc (GMA)-brazed non-load carrying joints made of S960 MC plates. CuMn13Al7 and CuAl8 were used as braze alloys. In addition, the work evaluated the potential of gas metal arc brazing (GMAB) as a post-weld improvement technique. A total of 21 different test specimens were manufactured and tested with constant amplitude fatigue tests with an applied stress ratio of R = 0.1. Notch effects of the braze joints were investigated numerically using finite element analysis (FEA). Depending on the braze alloy and joint configuration, mean nominal fatigue strengths of FATmean = 134-192 MPa were obtained, indicating that GMAB is a promising joining method for structures made of UHSS. The FEA results showed that for the studied materials and joints, stress concentration induced in the joint can decrease approximately by 20% when GMAB is applied instead of fusion welding.
