TI-6AI-4V laser weld at different depths through the thickness of the plate. Note the size and shape of the prior beta grains especially at the top and bottom of the weld (Kroll' etchant) zone (HAZ) of the pure titanium weld was a fine serrated alpha-Fig. 4. The HAZ of the Ti-6AI-4V was a mixture of primary alpha and transformed beta containing
Welding of dissimilar materials is an important object and has several industrial applications. In this article, the welding of 316L stainless steel sheets to commercially pure grade 2 titanium alloy (Ti Gr2) will be investigated. A pulsed laser was used for welding the SS/Ti sheets. A single Cu and Ag-Cu thin sheet were used as an interlayer to obtain excellent joint strength. Tensile test ...
Blue & yellow color combined surface after titanium welding ( Rejectable ). The dark blue, purple, or blue + yellow color indicates that heavier contamination may occur during welding. Generally, if the welding area exhibits one of these colors, the material shall be rejected. However, it may be acceptable depending on specific service.

Laser welding is a procedure in which metals or thermoplastics are connected to create a weld using a laser gleam. Due to the concentrated heat source, laser welding can be performed at high welding velocities in meters per minute in thin materials. In thicker materials, it can generate slender, deep welds between parts with square edges.
For welding at 125-200 amps, choose a rod diameter between 1/16-3/32”. For anything above 200 amps, the diameter should be between 3/32” to ⅛”. Tubes and pipes thinner than 5 mm should be welded autogenously (without any filler material) to minimize heat input.
Laser-Beam Welding. Similar to electron beam welding, this also involves the fusion of the two metals. This fusion results in the creation of a firm and durable piece. Many welders tend to use the laser beam rather than the electron beam for titanium welding because it removes the need for a vacuum chamber.
The other bonding technology that offers similar control is electron beam welding (EBW) where a beam of electrons heats the metal surfaces (instead of a beam of photons as in laser welding). Like laser welding, it also produces a direct metal-to-metal bond (no filler required, hence no filler contamination). However, unlike laser welding, which ...
In paper, weld joints between VT1-0 titanium and AISI 321 austenitic stainless steel using laser welding were obtained. To improve the quality and strength properties of joints, two types (SS–Cu ...
Figure 1. Laser-GMAW-P hybrid welding setup. Click here to enlarge image. A dramatic change in the weld quality was observed when laser power was added to GMAW-P welding of titanium. This work was accomplished with a Lincoln Electric GMAW-P power supply and a TRUMPF/Haas Nd:YAG laser. The lamp-pumped laser can deliver 4 kW in CW mode through a ...

The composition of Ti6Al4V. The laser beam is focused on titanium plates using 160 mm plano convex lens. The minimum spot size on the plates has been 0.4 mm. During welding application, the laser beam has been focused on 2 mm under the surface of the plates to obtain enough power density for the cross-section.
Laser beam welding is a good option for welding titanium. If part cleaning and gas cover are handled properly, the process will yield high quality welds at a reasonable cost. Typically, laser welding penetration can range up to 0.325” in titanium.

You can use resistance welding to join titanium and its alloys for a spot or continuous welds. It is particularly useful when it comes to welding titanium with other metals like carbon steel or stainless steel plates. Laser-Beam Welding (LBW) This is another fusion welding process that joins two pieces of metal together via a laser. It heats the intersection between the two plates, which melt and merge, forming the joint.
The electron beam welding of TC4 titanium alloy has few porosity defects in the weld. For this reason, the research focuses on the process factors for the formation of pores in laser welding welds. From the test results, it can be seen that when laser welding, the pores in the weld have a close relationship with the weld line energy.
Laser welding plays a critical role in the manufacturing of MIDs. While many of the internal components of MIDs can be joined by soldering, brazing, or welding, the entire device is often packaged in two titanium parts (shells), with laser welding serving as the preferred method for hermetically sealing the two shells.

Lasers tend to round or soften angles if you weld close to an edge. This requires extra build up and filing to restore the original shape of the piece welded. Unlike solder, laser welds do not flow through the seam of a joint. The weld is only as strong as the beam pulse penetrates the metal in the weld zone.
studies of laser welding of dissimilar metals have apparently been at tempted yet. The present investiga tion was initiated with the intent of metallurgically characterizing dis similar metal welds. The system chosen was titanium-nickel. Welding of titanium to nickel certainly presents some difficulties. Previous studies (Ref. 1) on the or
