Embodiment Construction

[0027] Below in conjunction with specific implementation, the embodiment of the present invention is further described:

[0028] Such as Figure 1 to Figure 8 The method for assembling and welding the root-free T-type penetration welding joint includes the following steps:

[0029] Step 1. Prepare the parts to be welded, welding consumables and auxiliary materials, including: 1 piece of web, 1 piece of wing plate, CO 2 Gas shielded welding equipment, submerged arc welding equipment, φ1.2mm solid-core welding wire, φ5.0mm solid-core welding wire, flux, some φ4.0mm×50mm welding wire heads, some anti-deformation supports, other auxiliary materials, etc.;

[0030] Step 2. Complete the groove processing of web 1 according to the design drawing, as attached figure 1 As shown, the groove angle α on both sides must meet the requirements (25°≤α≤35°), and the blunt edge of the groove should not be greater than 2mm;

[0031] Step 3. Place the wing plate 2 on the platform and draw the ...

Abstract

The invention discloses an assembling and welding method for a back-chipping-free T-shaped penetration welding joint. The method mainly comprises the following steps: vertically placing a web on the central line of a wing plate, and performing spot welding on each position where a welding wire head is placed by using CO2 gas shielded welding; obliquely placing anti-deformation supports on single sides of the wing plate and the web at certain intervals; laying welding flux on the back sides of web welding points, namely, paving the groove of the entire back side with the welding flux on one side where the anti-deformation supports are arranged; performing segmental discontinuous welding away from the spot welding positions by using CO2 gas shielded welding, and removing positioning welding spots and the welding wire heads by adopting carbon arc air gouging; repeating the process above to lay the welding flux and perform welding on a groove in the other side of the welded web; filling, and welding a covering surface by adopting submerged-arc welding. The method is convenient to operate, T-shaped penetration welding can be performed rapidly, the welding quality is ensured, and the welding procedure is simplified, thereby increasing the production efficiency and saving the production cost.

Description

technical field [0001] The invention relates to the technical field of welding processing, in particular to a method for assembling and welding T-shaped penetration welding joints free of root cleaning. Background technique [0002] Welding of steel structure engineering widely involves T-type penetration welded joints. During the welding process, carbon arc gouging is often required for such joints to ensure the internal quality of the weld. However, increasing the carbon arc gouging process of the entire weld bead will inevitably cause Increased time, cost and waste of material. [0003] Therefore, it is necessary to design a new welding process to meet the needs of the production process of T-shaped penetration welded joints without changing the existing processing equipment. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an easy-to-operate, fast T-shaped penetration welding, which not only ensures the weldi...
