Circulating blowing type electric welding work case for pipeline operation

Abstract

The invention discloses a circulating blowing type electric welding work case for pipeline operation, and the work case comprises a folding electric welding box which can achieve inflation and deflation. An electric welding nozzle pipe and an inwards-turning type grabbing glove are disposed to pass through the folding electric welding box. The folding electric welding box is also provided with an inert gas pipe, a circulating pipe, a workpiece entering closing door, and a gas exhaust door. The head and tail of the circulating pipe are respectively connected to a group of opposite surfaces of the folding electric welding box. The circulating pipe is sequentially provided with a circulating gas flow pump, a dedusting link, a gas filtering link and a high-temperature heating link in the gas flow direction. Compared with the prior art, the interior of the folding electric welding box is filled with inert gas, and an operator carries out operation of the folding electric welding box. The inert gas in the folding electric welding box continuously circulates for use, thereby reducing the consumption of inert gas, reducing the discharge of harmful gas, protecting the environment, and also protecting the safety of an operator.

Description

technical field [0001] The invention relates to a sealed electric welding work space, in particular to a circulation blast type electric welding work box for assembly line operation. Background technique [0002] In order to pursue the high strength of the welding point during welding, it is necessary to avoid the melting of the metal and other substances in the air during the welding process. Inert gas shielded welding is usually used, which uses argon or argon-rich gas as the protective medium, and adopts continuous feeding to melt The welding wire and the arc burning between the welding wire and the welding wire workpiece are used as the arc welding as the heat source, but the price of the inert gas is relatively expensive and the cost is high, and in the high temperature operation during the welding process, the harmful substances in the metal will be volatilized, causing pollution to the surrounding environment , causing damage to the health of surrounding personnel. ...
