Abstract
The utility model discloses a welding seam inert gas protects frock belongs to the welding technology field. This frock includes the open half casing that shelters from of at least one side, half shelter from the casing and have a apex angle, the apex angle inner point welds the fixed connection and has separates the reinforcing plate that forms even gas triangular cone space, the apex angle has the trompil with the intake pipe intercommunication that links firmly. During the welding, will open the gauze mask and wait for welding workpiece in flange, corner fittings, inert gas lets in even gas triangular cone space by the intake pipe, can shelter from the comprehensive protection of casing internal surface clearance formation to the welding position through reinforcing plate and half, the utility model has the advantages of simple and reasonable structure, convenient to use.
Description
Technical Field
The utility model belongs to the technical field of the welding technique and specifically relates to a welding seam inert gas protects frock, belongs to welding tool.
Background
In the industries of nuclear material manufacturing and processing and the like, equipment such as a glove box must prevent welding seams from being oxidized by means of a welding seam inert gas protection tool when welding workpieces such as lamp window flanges, corner fittings and the like. However, the shapes of lamp window flanges, corner fittings and the like of the glove box are special, and the existing welding seam inert gas protection tool can perform gas protection on a part of a welding seam, but cannot perform gas protection on the whole welding seam of the workpieces.
Disclosure of Invention
The utility model aims to provide an: aiming at the defects in the prior art, the welding line inert gas protection tool capable of performing effective gas protection on the special-shaped workpiece is provided through structural improvement.
In order to achieve the purpose, the utility model discloses basic technical scheme of welding seam inert gas protection frock does, including at least one side open partly shelters from the casing, partly shelter from the casing and have a apex angle, the apex angle inner point welds the reinforcing plate that even has the even gas of isolating formation triangular cone space, the apex angle has the trompil with the intake pipe intercommunication that links firmly.
During the welding, will open the gauze mask and wait for the welding workpiece in flange, corner fittings, inert gas lets in even gas triangular cone space by the intake pipe, can form the comprehensive protection to the welding position through reinforcing plate and half shielding casing internal surface clearance, the utility model has the advantages of simple and reasonable structure, convenient to use have overcome prior art's defect.

Detailed Description
Example one
The embodiment is a flange back weld joint protection inert gas protection tool, as shown in fig. 1 to fig. 3, a half shielding shell 1 with one open side is composed of a rectangular main board 1-1 with an observation window 1-3 and a surrounding board 1-2, a reinforcing board 2 is fixedly connected in a top corner of the half shielding shell 1 through spot welding, and the reinforcing board 2 not only separates a gas-homogenizing triangular cone space and fills a gas buffer, but also plays a role in reinforcing the rigidity of the half shielding shell 1. The air inlet pipe 3 is welded at the opening of the top corner.
When the flange is welded with a workpiece, the tool is covered on the back of a welding seam, then gas enters the gas-homogenizing triangular cone space through the gas inlet pipe, and after buffering, the gas enters the shell through the spot welding gap, so that the protection effect is achieved.
Example two
The embodiment is a welding seam inert gas protection tool for protecting the inner back of a special-shaped corner piece, and as shown in fig. 4 to 6, an open semi-shielding shell 1 is composed of a main plate 1-1 with a unfilled corner and a surrounding plate 1-2 with three edges. And a reinforcing plate 2 for separating a gas-filled buffer even-gas triangular cone space is fixedly welded in a vertex angle of the semi-shielding shell 1, and an air inlet pipe 3 is welded in an opening of the vertex angle.
When the special-shaped corner piece begins to be welded with a workpiece, the tool is covered on the back of a welding line, and then gas enters the shell through the gas inlet pipe made of stainless steel, so that the protection effect is achieved.
In addition to the above embodiments, other embodiments of the present invention are also possible. All technical solutions formed by adopting equivalent transformation or equivalent transformation all fall within the protection scope of the present invention.
