Description
Technical field
The utility model relates to the electroslag welding field of steel-structure box ellbeam post, relates to a kind of spark blowout and blow-out piece thereof of electroslag welding in particular.
Background technology
Electroslag welding is when utilizing electric current to pass through slag, and the resistance heat of generation melts mother metal and fills a kind of process that metal welds as thermal source.The resistance heat that produces during electroslag welding is as thermal source as shown in Figure 1, fusing mother metal and fill metal 4 and weld.It also belongs to the scope of automatic weldering.Electroslag welding is generally welded in vertical vertical position of welding, and run-on tab 6, web 7, two baffle plates 2 and a dividing plate 5 constitute welding beads, and spark blowout 8 is arranged on the welding bead top.When electroslag welding begins, produce electric arc earlier between welding wire 1 and run-on tab 6, the solder melts around the heat energy that electric arc produces makes becomes molten slag 3.After treating to form the molten bath of certain depth in the space of molten slag 3 between welded piece and cooling slide block, arc extinction at this moment, transfers the electroslag welding process to by the arc welding process.Because molten slag has certain electric conductivity, when welding current reaches workpiece through the molten bath, produces a large amount of resistance heats, and bath temperature can be remained on more than 1700 ℃, simultaneously, welding wire 1 and welded piece are heated by the molten bath and melt, and form metal bath.During welding, welding wire 1 is constantly sent to and is melted, and molten bath and slag bath rise simultaneously with cooling, below metal cooled and solidified gradually in the molten bath, form weld seam, in the floating superincumbent slag bath of slag and impurity.During the blow-out ending, will guarantee that finally weld seam exceeds spark blowout 8, just welding is finished, be for slag in the slag bath and impurity all being stayed in the spark blowout 8, not influenced composition of weld line to improve welding quality like this.Cut off run-on tab and unnecessary weld seam after the cooling, and reconditioning is smooth consistent with mother metal, and spark blowout 8 is taken down, remove slag to reuse.
Electroslag welding is generally used in steel-structure box ellbeam column production process, and the existing spark blowout 8 that adopts is the overall structure form of round casing.The high-temperature slag, fusing mother metal and the filling metal that rise from welding bead owing to the welding back cause the spark blowout distortion, make spark blowout 8 after welding finishes, be difficult for breaking away from slag, fusing mother metal and the filling metal of cooling, influence recycling effect, reduction of service life, reduce access times, increase use cost.
