The connecting rod 5 is hollow stepped cylinder body, and the hollow stepped cylinder body larger diameter end is provided with external screw thread, minor diameter
End end face is provided with three circular holes, and three circular holes spray for welding protection gas;
The ignition tip 6 is the ignition tip of the commercially available a diameter of 1.2mm of wire feed;
The protection nozzle 7 is hollow tube, and the hollow tube inwall is tapped with one section of internal thread, is spirally connected with connecting rod 5;
The male end of connector 3 is screwed tight with the female end of handle 1, the male end of bend pipe 4 and the female end spiral shell of connector 3
Tightly, the male end portion with external threads of connecting rod 5 is spirally connected with the internal thread of bend pipe 4;The internal thread segment of connecting rod 5 and the external thread section spiral shell of ignition tip 6
Connect, the protection internal thread of nozzle 7 is screwed tight with the male end another part external screw thread of connecting rod 5, ignition tip 6 is located in protection nozzle 7, flange
Lid 2 is set on the outer wall of handle 1.
The handle 1 and blind flange 2 are made of nylon material;The connector 3, bend pipe 4, connecting rod 5 and protection nozzle 7 are brass
Material is made, and the outer wall of protection nozzle 7 is provided with insulating barrier.
As shown in Figure 1 and Figure 2, the utility model local dry cavity drainage cover special welding gun under water, torch handle 1, blind flange is adopted
It is made of nylon material, nylon material coefficient of friction is big, and heat conduction is slower, welder can be allowed to operate more comfortable;It is connector 3, curved
Pipe 4, connecting rod 5 and protection nozzle 7 are made of brass material, and intensity is not high needed for welding gun, and Underwater Welding corrosivity is larger, brass
Corrosion is difficult, and the resistance of brass is relatively low, is adapted to do the conductive material of welding gun, and also its price is less than stainless steel.Welding is used
The flux-cored wire of a diameter of 1.2mm, therefore ignition tip selects diameter 1.2mm ignition tips, ignition tip material is red copper.
During installation, the female end that the male end of brass connector 3 is screwed into handle 1 is screwed tight, the male end of brass bend pipe 4

With the external thread bolt connection of ignition tip 6 on the internal thread of copper connecting rod 5, the internal thread of nozzle 7 then will be protected another with the male end of brass connecting rod 5
Portion with external threads is screwed tight, and finally blind flange 2 is set on the outer wall of handle 1.
The cable of welding gun is inserted by the round platform end opening of handle 1, is arranged on cable with externally threaded hollow circular cylinder,
The hollow circular cylinder is screwed tight with the internal thread of brass connector 3, and casting glue is poured into afterwards, it is ensured that the round platform end end face aperture of handle 1 has
Casting glue flows out, after standing one day, with adhesive tape by cable and handle round platform end face joining part rubber belt sealing.The cable of welding gun
Using the commercially available common land cable of gas shielded welding gun.The length of its internal wire feed flexible pipe needs to be entered according to length of cable
Row cuts, and generally to ensure that wire feed flexible pipe stretches out 10 to 15mm from welding gun brass bend pipe 4.
When using, in the silica-gel gloves structure hole that welding gun brass bend pipe 4, brass connecting rod 5, protection nozzle 7 pass through drainage arrangement
Insertion, handle 1, brass connector 3, blind flange 2 stay in the outside of silica-gel gloves, if welding gun can not drive silica-gel gloves after insertion
It is any mobile together, then blind flange 2 is screwed on gloves.
What is led in welding gun is the mixed gas of carbon dioxide and argon gas, and (i.e. welding gun insertion draining is filled before water under welding gun
Before the silica-gel gloves structure hole put) gas is first passed through, prevent inwelling from entering welding gun, influence welding.Wire feed in cable
Flexible pipe will keep drying, can otherwise influence welding quality.
Welding gun need to be inserted drainage arrangement by welder in welding from silica-gel gloves, and handle is in the outside of drainage arrangement for weldering
Work is grasped, and controls the movement and swing of welding gun.If silica-gel gloves can not be moved together with welding gun, blind flange of screwing on.Welded
Protect gas open-minded always in journey.
In welding, because welder's operational error or other reasonses cause ignition tip to burn out, it is necessary to what is more renewed in time leads
Sparking plug, and protection nozzle needs timing to change, it is ensured that the insulating barrier of protection nozzle is without breakage.
It is noted that welding gun putting position, prevents high temperature silica-gel gloves after welder's welding.Gas in welding gun will continue
Supply, supply can be stopped until welding terminates rear welding gun water outlet disembarkation.
The utility model has the advantages that:Welding gun good airproof performance, outside seawater in itself cannot be introduced into adhesional wetting welding wire in gun body;Weldering
Rifle is fitted close with drainage cover silica-gel gloves, it is ensured that when welder's operation welding gun is welded, seawater will not be from silica-gel gloves
Into in drainage cover, it is possible to achieve welded with reliably carrying out local dry cavity under water in the range of the shallow depth of water at 60 meters.
Welder's hand torch handle, by the aperture of welding gun insertion drainage cover silica-gel gloves, allows welding gun in drainage cover
Inside move freely, and the sealing effectiveness of drainage cover can be ensured, welding gun afterbody is carried out close with cable contact part by casting glue
Envelope;The handle and blind flange of welding gun are made of nylon material, and the coefficient of friction of nylon material is high, and insulation and thermal insulation, convenient weldering
Work is operated, good sealing effect.The connector of welding gun, bend pipe connecting rod, ignition tip and protection nozzle are made of brass material, are selected
Brass can reduce the corrosion loss that operation on the sea corrosion brings, and brass conductive is good.
