Problems solved by technology

However, in terms of the welding performance of the material itself, the main component of the galvanized sheet is Zn and Fe. In addition, elements such as S, P, Si, Mn, and H also exist. A large amount of spatter will be generated during the welding process, and the weld seam Inclusion of pores, cracks after welding cannot be completely avoided. Welding cracks are not only a huge welding defect, but also bring safety hazards

Embodiment 1

[0039] Put a piece of A4 paper flat between two galvanized sheets, arrange the galvanized sheets according to the position requirements, and use the pressing fixture to fix the galvanized sheets; import the welding pattern into the welding software of the electric control cabinet , place the clamping fixture of the galvanized sheet on the workbench 24, and fix the pressing fixture at a fixed position below the vibrating head 25; Wipe it clean and air-dry; set the slow down on the electric control cabinet, reserve 5mm length for straight line welding, slow down the power to end, the air blowing tank 14 blows protective gas at the bottom of the galvanized sheet, and the vibrating head 25 completes the welding with a low power output of 400W The surface of the part is preheated, and the deep penetration welding of the part to be welded is completed with a high power output of 2100W. The interval between two steps of welding is 300ms. 40mm / s.

Embodiment 2

[0041]Put a piece of A4 paper flat between two galvanized sheets, arrange the galvanized sheets according to the position requirements, and use the pressing fixture to fix the galvanized sheets; import the welding pattern into the welding software of the electric control cabinet , place the clamping fixture of the galvanized sheet on the workbench 24, and fix the pressing fixture at a fixed position below the vibrating head 25; Wipe clean and air-dry; set the slow down on the electric control cabinet, reserve a 30° angle for the slow down to finish, the air blowing tank 14 blows protective gas at the bottom of the galvanized sheet, and the vibrating head 25 completes the part to be welded with a low power output of 500W Preheat the surface of the welding surface, complete the deep penetration welding of the part to be welded with a high power output of 2500W, the interval between two steps of welding is 300ms, the swing width of the beam in the vibrating head 25 is 1.2mm, the f...

Abstract

The invention discloses a galvanized sheet laser penetration welding device which comprises an electric control cabinet, a working table is arranged on the electric control cabinet, a servo module is arranged on the working table, a vibration lens is arranged on the servo module, a pressing jig is arranged on the working table, the pressing jig comprises a bottom plate fixedly connected to the working table, and the bottom plate is fixedly connected to the working table. A pressing plate is fixedly connected to the upper end face of the bottom plate, an air pipe connector is arranged on the side edge of the bottom plate, and an air blowing groove is formed in the upper end face of the bottom plate. According to the method, two-step welding is adopted, the effect of welding after preheating is achieved, the crack tendency caused by uneven shrinkage of welding seam cooling after welding due to too large base metal temperature difference is avoided, the welding spatter tendency is more easily reduced through the arrangement of the high speed, the low swing width and the high swing frequency of vibration lens welding, and the welding quality is improved. Arc craters at the welding ending position are avoided through the power slow-descending arrangement at the welding ending position, and therefore weld joint arc crater cracks are avoided.

Description

technical field [0001] The invention relates to the technical field of laser welding, in particular to a laser penetration welding galvanized sheet equipment and method. Background technique [0002] Compared with stainless steel, galvanized sheet also has corrosion resistance, and the internal material is mostly carbon steel, which also makes galvanized sheet have the characteristics of high strength, high hardness, and easy cutting and processing. The automotive industry, especially in the field of heavy transport vehicles Apply galvanized sheet. However, in terms of the welding performance of the material itself, the main component of the galvanized sheet is Zn and Fe. In addition, elements such as S, P, Si, Mn, and H also exist. A large amount of spatter will be generated during the welding process, and the weld seam Inclusion of porosity, cracks after welding cannot be completely avoided, welding cracks are not only a huge welding defect, but also bring safety hazards....
