Example Embodiment
[0034] Example one:
[0035] Such as Figure 1 to Figure 3 As shown, the vacuum electron beam welding method of magnesium alloy components of the embodiment of the present invention includes the following steps:
[0036] 1) Selection of welded parts: the welded joint adopts a complete butt joint and a round magnesium alloy blank; in this embodiment, electron beam welding is performed on 20 circular magnesium alloy blanks with an outer diameter of 130mm and an inner diameter of 20mm;
[0037] 2) Cleaning the welded parts: Wipe and clean the magnesium alloy blanks and complete butt joints. Use a clean white gauze dipped in acetone to wipe and clean the weldments to remove the oil film, water film and organic impurities on the surface to be welded. The surface is not allowed to be touched and recontaminated;
[0038] 3) Assembly: After cleaning, all welded parts are assembled and welded, and special tooling fixtures are used for assembly during assembly. The assembly gap is less than 0....
Example Embodiment
[0048] Embodiment two:
[0049] The difference between this embodiment and the first embodiment above is only: 1) Choose 20 magnesium alloy blanks with an outer diameter of 140mm and an inner diameter of 20mm; 2) Welding speed V 0 Use 600mm / min, electron beam current L 0 Using 115.0mA, focusing current I 0 Using 2.65A, focus current I 1 = 3.35A.
[0050] The weld penetration depth of the magnesium alloy component obtained by the above vacuum electron beam welding method is 55mm-60mm, and the weld surface and subsurface have no pores, and the pores inside the weld and the arc are dispersed and the diameter of a single pore is less than 1.2mm. There are no other welding defects such as cracks, slag inclusions, etc. in the weld, which means that the welding quality is better while obtaining a larger penetration depth.
Example Embodiment
[0051] Embodiment three:
[0052] The difference between this embodiment and the first embodiment above is only: 1) Choose 20 magnesium alloy blanks with an outer diameter of 140mm and an inner diameter of 20mm; 2) Welding speed V 0 Using 650mm / min, electron beam current L 0 Using 110.0mA, focusing current I 0 Using 2.60A, focusing current I 1 = 3.30A.
[0053] The weld penetration depth of the magnesium alloy component obtained by the above vacuum electron beam welding method is 55mm-60mm, and the weld surface and subsurface have no pores, and the pores inside the weld and the arc are dispersed and the diameter of a single pore is less than 1.2mm. There are no other welding defects such as cracks, slag inclusions, etc. in the weld, which means that the welding quality is better while obtaining a larger penetration depth.
