Laser cutting machine and laser welding machines are widely used in the following industry, such as sheet metal fabrication, metallic job-shops,Elevator industry,Shipyard building industry,Food and drugs machine manufacturing, other machine manufacturing…
1.keyhole definition Keyhole definition: When the radiation intensity is greater than 10^6W/cm^2,When the surface of a material melts and evaporates under the action of a laser, and when the evaporation speed is sufficiently large, the recoil pressur...
1.Laser thermal conductivity welding definition and characteristics Laser thermal conductivity welding is a method of laser welding. This welding mode has shallow penetration depth and small depth-to-width ratio.When the power density is less than 10...
Plasma effect in laser welding process In the laser welding process, plasma is a common phenomenon, which has an important impact on the effect and quality of the welding process.Plasma is composed of ionized gas in which atoms or molecules in the ga...
1.1 Changes in physical state caused by the interaction between laser and materials The laser processing of metallic materials is mainly a thermal processing based on photothermal effects. When the laser irradiates the surface of the material, variou...
1.Laser weld seam tracking principle The laser-seam tracking sensor operates on the principle of laser triangulation. That is, the laser beam is amplified to form a laser line projected onto the surface of the object being measured. The reflected lig...
0 PrefaceRed copper has good ductility, high thermal conductivity, and electrical conductivity, and is widely used in aerospace, marine engineering, cable and electrical, and electronic components.Traditional red copper welding methods such as tungst...
0 Preface TC4 Titanium alloy is a typical α+β type dual-phase titanium alloy featuring low density, high specific strength, and excellent corrosion resistance. Its superior overall performance makes it widely utilized in various field...
Abstract:For the welding of copper in battery connector , pulse laser and continuous fiber laser were used to laser welding testing. For pulse laser , process parameters of peak power , pulse width and focal distances were carried to orthogonal ...
ABSTRACT:The work aims to study the optimum laser welding process scheme for 6063 aluminum alloy to improve the ten- sion of welding spot in view of that the tension of 6063 aluminum alloy spot-welded by pulse laser is low and fails to meet...
