Problems solved by technology

If the length of the composite slab reaches more than 10 meters, it will be difficult and costly to configure the production conditions such as the turning positioner, welding equipment, and the height of the workshop
[0013] 2) For the sealing and welding of composite panels with thick cladding materials, the size of the weld groove is too large, and the sealing and welding efficiency is low

Embodiment 1

[0048] A method for sealing and welding symmetrical hot-rolled clad plate slabs, the technical scheme and steps are as follows:

[0049] 1. S1 designs and manufactures a frame with a special structure. For the specific structure and size of the frame, see figure 2 shown.

[0050] cladding side of the enclosure ( figure 2 The left side of the isosceles trapezoid is designed as an isosceles trapezoid, the length of the lower base of the isosceles trapezoid is greater than or equal to the sum of the thicknesses of the upper and lower cladding materials, and the length difference between the lower and upper bases of the isosceles trapezoid is not limited. And the preferable range is 2mm to 20mm.

[0051] outside the frame ( figure 2 On the right side of the cross-section, a certain length is reserved on the upper and lower sides as the blunt edge of the weld bevel. The optimal range of the blunt edge length is 2-5mm, and the other parts are designed to be trapezoidal. The l...

Embodiment 2

[0062] A symmetrical hot-rolled composite plate slab, the overall structure of which is as follows Figure 4 As shown, it includes an upper base material, a lower base material, a covering material and a surrounding frame. The upper base material and the lower base material cover the upper and lower sides of the covering material. The base material and the lower base material are welded separately, and the frame includes two parts, the first part constitutes the inner periphery of the frame, its cross-section is isosceles trapezoidal, the upper bottom edge is connected with the cladding material, and the second part constitutes the outer periphery of the frame , its cross-section is trapezoidal, the lower base of the second part is connected to the lower base of the first part, and the length of the lower base of the second part is smaller than the lower base of the first part, and the end of the upper substrate There is a bevel on the side close to the frame. The length of t...

Abstract

The invention relates to a symmetrical-hot-rolled composite plate blank and a seal welding method thereof. An enclosure frame comprises two parts, the first part forms the inner side of the enclosureframe, and the cross section of the first part is an isosceles trapezoid; the second part forms the outer side of the enclosure frame, the cross section of the second part is trapezoidal, and the length of the lower bottom edge of the second part is smaller than the length of the lower bottom edge of the first part; a groove is formed in the side, close to the enclosure frame, of the end of an upper base material; a special groove structure is formed through the innovative enclosure frame structure design, and the seal welding process is innovatively divided into two welding process flows; automatic welding equipment such as an arc welding robot or a special machine is adopted, and laser weld joint tracking and self-adaptive welding equipment is configured; a horizontal position welding mode is adopted, a high-penetration welding process is adopted for a root welding bead, and a high-deposition-rate welding process is adopted for a filling welding bead; and compared with the prior art,high-quality, high-efficiency and low-cost seal welding is realized through unique methods such as enclosure frame structure design, groove structure design, two-step welding process flow, welding process optimization and automatic welding equipment.

Description

technical field [0001] The invention relates to a production method of a symmetrical hot-rolled composite plate, in particular to a symmetrical hot-rolled composite plate slab and a sealing welding method thereof. Background technique [0002] The overall technological process of symmetrical hot-rolled composite plate manufacturing includes: plate pretreatment, plate assembly, sealing and welding, vacuuming, hot rolling and finishing separation. The hot-rolled clad plate slab generally adopts the following structure, as shown in the attached drawing figure 1 As shown, there are two layers of cladding material in the middle, and the upper and lower pieces are the base material. The surrounding frame is fixed around the cladding material. The groove formed by the material must be fully welded. One or two air holes are set on the substrate or the surrounding frame for vacuuming. After the vacuum degree meets the requirements, the final welding is carried out, and the vacuum i...
