Embodiment 1

[0044] Raw material preparation:

[0045] 1) Double board: material TA1, finished medium and thick plate, size 30×1900×3800mm. Processing requirements: the surface is flat and free of defects, no wedge shape or camber is allowed, the unevenness is ≤3mm / m, the roughness Ra is less than 5.5μm, and it has been pickled deeply, and there is no oxide point after pickling;

[0046] 2) Substrate: material Q235, size 150×2010×3910mm. Single-sided milling depth ≥ 5mm;

[0047] 3) Side strips: design two long and short side strips: long side strips (mm): length = 3910, width = 50, thickness = 63; short side strips (mm): length = 1910, width = 50, thickness =63.

[0048] 4) Others: industrial alcohol with a concentration of 99.95%; non-woven fabrics; release agent.

[0049] Stitching of side strips:

[0050] 1) Groove: Groove at 5-6° on the outside of both ends of the short side strip, with a depth of about 20mm. For both ends of the long side strips, make a groove of 5-6° at the co...

Abstract

The invention discloses a vacuum electron beam welding method of a titanium steel composite billet using an edging assembled billet. According to the method, 1) by adopting the scheme that an edging design is used in the field of vacuum electron beam welding and edgings are sealed and welded in advance, the technical problem that a vacuum electron beam cannot be used for welding vertical seams issolved, and the accuracy and speed of processing assembled billets are improved; 2) for the first time, it is proposed that a titanium plate is sealed and welded in advance, so that the hidden dangerthat a parting agent may scatter and pollute a composite layer during rolling is solved; and the consumption of steel materials and production costs are greatly reduced by replacing a traditional catching groove process with the edging assembled billet process provided by the invention, flaw detection results of a slab after rolling are all qualified, and the performance is much higher than the user requirements, therefore, a strong technical support is provided for expanding the production of high-quality products.

Description

technical field [0001] The invention belongs to the technical field of metal material processing, and in particular relates to a vacuum electron beam welding method for forming titanium-steel composite blanks by using side strips. Background technique [0002] The rapid development of science and technology has put forward higher requirements for advanced manufacturing and processing technology. The primary indicator is to focus on energy saving and consumption reduction, followed by the improvement of safety and service life. On this basis, the overall upgrade of structure or equipment functionality is achieved. In practical applications, the structure of a single material is often difficult to meet the above requirements, and the composite structure of dissimilar materials can combine the advantages of the two materials to minimize costs and improve performance. [0003] At present, there are four main methods for producing titanium-steel clad plates: explosive cladding, d...
