The inventive welding process adopts the box-shaped protection device to perform argon gas protection on the back of the mirror stainless steel plate, is convenient to operate, and can well ensure stainless steel plate quality. The protection device main body is mounted to the back of the stainless steel plate by use of a sucking disk, thereby facilitating quick dismounting and quick mounting and at the same time avoiding marks left on the back of the stainless steel plate.
Description
Technical field
The present invention relates to a kind of technology, relate in particular to a kind of two-sided protection welding procedure that is used for the mirror face stainless steel plate corrosion resistant plate protection welding.
Background technology
The corrosion resistant plate any surface finish has higher plasticity, toughness and mechanical strength, and the corrosion of acid and alkali resistance property gas, solution and other media is a kind of steel alloys that are not easy to get rusty.But when it is welded; The oxidation blackout needs technologies such as extra cleaning of later stage, polishing to repair easily, and increasing cost influences the corrosion resistant plate quality again; Especially surface finish becomes the corrosion resistant plate of minute surface; Surface of steel plate has very high reflectivity, causes easily during welding splashing, and welding quality is difficult to control.Therefore, be employed at present and charge into nitrogen or argon gas around the position to be welded and come method that it is protected, but only in the corrosion resistant plate front argon gas or nitrogen are set usually, the reverse side of corrosion resistant plate lacks protection, still oxidation blackout easily.
Summary of the invention
The present invention has overcome the deficiency of prior art, provides a kind of technology simple, two-sided argon shield, the welding procedure that is used for the mirror face stainless steel plate that welding quality is good.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of two-sided protection welding procedure that is used for the mirror face stainless steel plate; It is characterized in that: said processing step comprises that (1) polishes flat position to be welded, said corrosion resistant plate surface, totally, and (2) are installed in top, said position to be welded with welder, and wherein the muzzle of welding gun is over against position to be welded; (3) obverse and reverse at position to be welded all adopts high-purity argon gas protection; (4) use said welding gun to weld, (5) welding finishes the welding position is carried out solution treatment, then cooling;
In the step (3), the reverse side at said position to be welded is provided with protective device, and protective device comprises box-like body, treats the welding position reverse side and protects through in said body, being full of high-purity argon gas.
In preferred embodiment of the present invention, further comprise said body one end opening, and openend is provided with sucker.
In preferred embodiment of the present invention, comprise that further said protective device also comprises the air duct that is communicated with said body interior, is provided with flowmeter and control valve in the pipeline.
In preferred embodiment of the present invention, the flow that the reverse side that further comprises said position to be welded charges into high-purity argon gas is 12-28L/min.
The invention solves the defective that exists in the background technology, welding procedure of the present invention adopts box-like protective device that mirror face stainless steel plate reverse side is also carried out argon shield, and is easy to operate; Ability is secluding air well; Solder joint is even, does not have splash phenomena, guarantees the corrosion resistant plate quality.Can adopt sucker that the protective device body is installed to the corrosion resistant plate reverse side, be convenient to promptly tear open immediate shipment, avoid simultaneously leaving a trace at the corrosion resistant plate reverse side.Can also on the air duct that feeds body, flowmeter and control valve be set, help controlling the conveying of argon gas immediately or stopping, and the gas pushing quantity of argon gas, under the prerequisite that guarantees welding quality, can save the argon gas consumption, reduce cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representation of protective device in the preferred embodiment of technology of the present invention;
Among the figure: 1, mirror face stainless steel plate, 11, the front at position to be welded, 12, the front at position to be welded, 2, body, 3, welding gun, 4, air duct, 6, flowmeter, 8, control valve, 14, sucker.
The specific embodiment
Combine accompanying drawing and embodiment that the present invention is done further detailed explanation now, these accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, a kind of two-sided protection welding procedure that is used for the mirror face stainless steel plate of the present invention, processing step comprises:
(1) thickness is processed into double-U-shaped groove at the mirror face stainless steel plate 1 surperficial position to be welded of 0.8-1.5mm with mechanical means, and both sides 5mm scope area inside and outside the groove is polished flat, totally.
(2) welder is installed in top, said position to be welded, wherein the muzzle of welding gun 3 is over against position to be welded.
The front 11 of (3) treating the welding position adopts 99.99% high-purity argon gas to protect flow 12-28L/min; At the reverse side 12 at position to be welded the protective device that is full of 99.99% high-purity argon gas is installed and is protected 12-28L/min.
Said protective device comprises box-like body 2, is communicated with the air duct 4 of said body 2 inside and is located at the flowmeter 6 and control valve 8 in the pipeline 4.Said body 2 one end openings, opened end section are greater than position to be welded, and openend is provided with circumferential equally distributed 12-24 sucker 14; Sucker 14 axis normal are in opened end section, disk body outwardly, before the welding; Protective device is adsorbed in said position to be welded reverse side 12 through body 2 openend suckers 14, and guarantees that whole position to be welded reverse side 12 places box-like body, opens control valve 8; Through air duct protective gas 99.99% high-purity argon gas is charged into body 2 inner chambers, control flow, through control valve 8 adjustment flows through flowmeter 6; To body 2 inner chambers, be full of argon gas, closed control valve 8.Said protective gas can be 99.99% high-purity argon gas, also can be to be main mist with the argon gas.
