The technical scheme that the utility model adopts for its technical problem of solution is:
Welder, comprises workpiece to be welded, welding rod, electric welding machine, protective cover and getter device; Protective cover is provided with soldering turret, and soldering turret can move up and down on protective cover, and the two sides of protective cover are provided with suction nozzle, and suction nozzle is provided with a pair; Be provided with welding rod in protective cover, welding rod is connected with soldering turret, and the lower end of protective cover is provided with workpiece to be welded, has weld seam between workpiece to be welded, the welding rod in protective cover and can form electric arc between workpiece to be welded, and electric arc is positioned at commissure; The side of protective cover is provided with electric welding machine, and the opposite side of protective cover is provided with getter device, and electric welding machine and getter device lay respectively at the both sides of protective cover, and getter device is connected with suction nozzle; One termination electrode of electric welding machine is connected with soldering turret, and the other end electrode of electric welding machine is connected with workpiece to be welded; Workpiece to be welded and welding rod form closed-loop path under the effect of electric welding machine, and workpiece to be welded can in formation molten bath, commissure;
In one embodiment, electric welding machine is silicon rectifier formula dc welding machine, improves the quality of weld seam;
In one embodiment, protective cover is clear glass material, is convenient to the welding situation of observing weld seam;
Operation principle is: before welding, is connected respectively by welded piece and clamps welding rod with soldering turret with soldering turret with the two poles of the earth of electric welding machine.Make welding rod and workpiece instant contact during welding, form short circuit, be separated by a distance (about 2-4mm) with by them, just ignited electric arc.Workpiece under electric arc melts formation semioval shape molten bath immediately.After the coating fusing on welding rod surface, a part becomes gas and surrounds electric arc and make it and air exclusion, thus makes liquid metal avoid the infringement of oxygen, nitrogen; A part becomes molten slag, or sprays to molten bath separately, or sprays to bath together with the liquid metal molten drop generated with two cores melting.In electric arc and molten bath, can there is certain physicochemical change in liquid metal, slag and arcing gas with each other, as gas dissolves in liquid metal, carries out redox reaction etc.Gas in molten bath and slag float because quality is light.After electric arc is removed, temperature reduces, and metal and slag can first after coagulations.Such two pieces metal through melting crystal weld metal and couple together.Slag due to amount of contraction different from metal, can on skull and metal circle, produce slippage, skull or Automatic-falling, or come off after knocking, the metal welding seam of band scalelike mark shape can be exposed.
The utility model has the advantage of:
1. protective cover is provided with soldering turret, soldering turret can slide on protective cover, reduces the molten assorted splashing of welding rod and commissure formation, avoids the molten assorted scald personnel of splashing or encounters combustibles causing fire incident, improve security.
2. protective cover both sides are provided with suction nozzle, and suction nozzle is connected with getter device, not only can suck the flue gas produced when welding rod and workpiece just weld, reduce flue gas to the injury of human body, also can siphon away the partial heat of commissure, accelerate the cooling of weld seam, be beneficial to coming off of skull.
3. electric welding machine adopts silicon rectifier formula dc welding machine, and cost is low, noise is little, easy to maintenance and structure simple, and the voltage and current direction of dc welding machine is constant, electric arc can be made to continue and smooth combustion, weldquality can be made to ensure to some extent.
