Tests of laser welding on bronze and stainless steel

At Lantec laser we are developing a series of tests of laser welding on bronze and stainless steel, trying to achieve balance, stability and above all quality in the solutions we offer.

This is an alternative to traditional welding using silver, which reduces costs and the thermal effect on the parts. It also improves the time involved in laser welding.

New try out to test laser welding control system

Lantec is running a test to prove reliability of 4D Weld Watcher system. According to the manufacturer, partially ionized metal vapour is created during laser welding, cutting or soldering. This escapes from the weld pool and emits a broadband light, the so-called process light. The WeldWatcher measures this process light using a photo-electric sensor. By doing so, typical features, such as the beam flux density, spectral components, time or progress are analyzed and used for quality control.

New test is carried out in Lantec to consolidate process of laser welding.

In this case we are laser welding 0.3 thick Alu plates together. 

First tries are done preparing butt welding tool with good results at 1.2 m/min. However tensile test results are giving low values for the expected target. 

Secondly, overlap (0.3 + 0.3) welding shots are produce, lowering power and using 600 w pulsed power laser. Results as shown in the picture are more likely to be accepted by the customer. Additional challenge is to avoid heat damage on the outer side of the plate. By producing 0.4 mm welds (106 microns spot) and 0.5 mm penetration we see there is a steady process and good tensile resistance goal is achieve.

Laser welding applied to the manufacture of cutting discs

Recently we have investigated the manufacture of diamond cutting discs in our laser welding laboratory. Discs are used mainly in the construction field, allowing clean and quick cuts in a wide range of materials. They are constructed by a serrated disc, with a hardened outer zone, usually with diamond.

New process is going on in Lantec to define parameters for HIPS material.

Customer requires a clean and fast cut to go forward with the investment. State of the art has not reach both levels at the same time invalidating any chance of industrialization.-

Welding laser procedures

Welding metal pieces, in order to joint components, is a common solution in our customer’s procedures.

Thus, we give more efficient and cost-effective solutions to manufacture processes that involve complex needs. To joint these components two types of laser welding can be used, depending on the angle and the pieces position, and these are overlap seam and Butt joint.
