Nuevos ensayos para la parametrización de soldadura láser en la fabricación de extintores.
Se llevan a cabo ensayos en Lantec para parametrizar la soldadura láser de dos cachas de inoxidable que han de conformar un extintor.
Se trata de soldar a testa un espesor típico de 1.5 mm y un diámetro de 150 mm.
We are running a new project to automate a laser marking process for one of the most important hand tool maker in Europe.
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.
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.
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.
Tests to define the conditions and parameters of laser welding in aluminum parts for applications where some significant amount of electric current may be required.
The desired welding is due to the characteristics of quality that are listed below.
