Using welds

This research investigates a means of negating such shortcomings and reaping the benefits of both LPBF additive manufacturing and traditional manufacturing methods by joining such parts together using laser welding in the autogenous mode (no fillers required). Based on the literature review conducted in this field and the gaps identified, a two-stage methodology was utilised, as per following.

A gas metal arc welding robot was used to build a thin-walled component made of mild steel on a low-carbon substrate according to the AM principle. Thereafter, the specimens for observing microstructures and mechanical properties were extracted from the built thin-walled component. The microstructures of the specimen were observed by an optical microscope; the hardness was measured by a digital microhardness tester, and the tensile tests were carried out on a tensile test machine.

A review of some recent data from multiaxial fatigue data from different notched materials is carried out in the paper. The approach based on the strain energy density (SED) averaged over a control volume is first used to summarise uniaxial and multiaxial fatigue strength data of welded joints made of structural steel and aluminium alloys.

This work is focused on the influence of different friction stir welding (FSW) parameters on AA6082 T-6 and AA5083-O alloys welding quality, by using Taguchi, Grey Relational and Weight Method. Four welding parameters were investigated, namely tool rotation speed (TRS), welding speed (WS), tool pin profile (TPP) and shoulder diameter (SD).

This paper presents the effect of vibratory dissimilar TIG (Tungsten Inert Gas) welding process on hardness of welded joins with respect to change of vibratory parameters. In this study, new vibratory setup with two metal engravers is used to give mechanical vibrations to the specimens to be welded.

The results show that ultimate strength under static loading can not be used as a quality criterion for zirconium alloys welds. Increased shielding gas flow rate does not allow to protect weld metal totally and contributes to defect formation without using special nozzles. Several types of imperfections of the welds have been found, but the major problem is branching microcracks on the surface of the welds.

Use drive rolls with a V-groove and flat pressure rolls. ✓ Use knurled rolls only when friction in the liner causes smooth rolls to slip e.g. with long, extremely curved cable assemblies. Knurled rolls give increased liner and contact tip wear. ✓ Check that the groove size is correct for the wire diameter. ✓ Apply the correct pressure on feed rolls. Too much pressure flattens the wire, resulting in feedings problems and higher liner and contact tip wear.

Welding joints are formed by welding two or more workpieces, made of metals or plastics, according to a particular geometry. The most common types are butt and lap joints; there are various lesser used welding joints including flange and corner joints. Invite you to reference the following presentations.
