“…In addition to the heat treatment that the metal alloy is exposed to due to the welding process, the pH values and temperature of the solution environment to which the alloy is exposed also affect the corrosion behavior. [45][46][47][48][49]. It is known that metals exposed to acidic environments and high temperatures have an increased tendency to corrode [50][51][52][53][54].…”

The corrosion resistance of laser welded samples was carried out in a shaken incubator in body-simulated liquid environments and kept at pH3-5 and 25-50˚C conditions for 24 hours. It was determined that acicular α' martensite structures were formed in the fusion regions and these structures increased the hardness of the alloy by 20% compared to the base metal. The welded samples had the highest tensile strength of 144 MPa. Weight changes after the corrosion test were calculated and the highest weight loss was found to be 0.0025 g for the sample with an initial weight of 4.1394 g. TiO2 oxides and {1 0 0} and {1 1 1} chamber-shaped salt crystals were formed larger and more intensely in the fusion zones than the base metal. Dental metallic implant welding with fiber laser will have higher corrosion resistance in oral use with different temperature and pH environments compared to screw joints.

“…The research on the joining of TC4 alloy has been well reported, such as tungsten inert-gas welding (TIG) [4][5][6], metal inert-gas welding (MIG) [7], electron beam welding [8][9][10][11], laser beam welding [12][13][14], and laser-MIG hybrid (LAMIG) welding [15,16]. Among these welding techniques, LAMIG welding is suitable for the joining of TC4 alloy.…”

In this paper, thick-section TC4 alloy was welded to itself by laser-MIG hybrid (LAMIG) welding. The microstructure of the welded joints was characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results revealed that α’ and β phases were formed in the weld seam. The effects of heat input (E) on the microstructure and tensile strength of the joints were investigated. With the increase of heat input, the residence time of platelet α’ martensite in the high-temperature phase changing zone became longer and the thickness of platelet α’ martensite increased. Furthermore, the β thickness became large, and tangling dislocations were found to exist in platelet α’. In addition, the increasing heat input could cause a decrease in the tensile strength. The failed dimple pattern experienced a change from equiaxed to tearing, which was harmful to the property of the joint.
