Embodiment

[0111] Embodiment: As shown in the figure, a welding construction method of a low background stainless steel 06Cr19Ni10 structure is carried out according to the following steps:

[0112] (1) Welding process:

[0113] 1) Cleaning before welding and cleaning between layers:

[0114] ①. Before welding, it is necessary to remove all kinds of pollution that may increase the carbonization of the weld metal, and the cleaning range is within the range of 20-30mm of the assembled welding groove and welding area;

[0115] ②. Grinders and stainless steel wire brushes should be used for cleaning between layers, and carbon steel wire brushes should not be used to clean the groove and weld surface;

[0116] ③. Take corresponding protective measures for semi-finished products to ensure that the assembled stainless steel components will not be polluted by dust and oil in the workshop;

[0117] 2), tack welding:

[0118] ①. Tungsten argon arc welding is used for positioning welding, the po...

Abstract

The invention relates to a welding construction method, in particular to a welding construction method of a low-background stainless steel 06Cr19Ni10 structure. The method comprises the following steps of thewelding process, the welding sequence and the welding direction, back chipping of welding lines, and notes during welding. With the welding construction method of the low-background stainlesssteel 06Cr19Ni10 structure, the welding speed and the welding quality are improved.

Description

technical field [0001] The invention relates to a welding construction method, in particular to a welding construction method of a low background stainless steel 06Cr19Ni10 structure. Background technique [0002] The low-background stainless steel material involved in the welding construction of the present invention is 06Cr19Ni10, and the involved stainless steel construction structure H-shaped steel component products are all welded by low-background stainless steel due to the requirements of the experimental environment, and the welding materials involved in product welding also need to be tested. Sampling for radioactive low background testing. [0003] Chinese patent 201811196771.7 discloses a stainless steel thin tube cold metal transition welding process, including the following welding steps: use acetone to remove surface oil stains and dust on the stainless steel thin tube to be welded, and polish the stainless steel surface. The finish of the stainless steel surfa...
