The large-diameter flange build-up welding device adopting the CO2 gas shielded welding has the advantages that welding cost is low, production efficiency is high, the range of application is wide, crack resistance is strong, slag removing is not need after welding, monitor and control are convenient, the mechanization and the automation of the welding process are convenient to achieve, manpower resources are greatly saved, welding quality is good, production efficiency is improved, and production cost is lowered.
Description
Technical field
The utility model relates to flange resurfacing welding equipment, relates in particular to a kind of employing CO
2The Big Diameter Flange surfacing equipment of gas shielded arc welding.
Background technology
Vast pressure vessel manufacturers is in manufacture process, and SMAW and the Lincoln weld of the band utmost point are generally adopted in the built-up welding of Big Diameter Flange.And the productivity ratio of manual electric arc welding is low, the quality of weld metal is unstable, and outward appearance is not attractive in appearance, adopts by contrast band utmost point submerged arc Lincoln weld cost high.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in prior art.
The utility model content
The purpose of this utility model is to provide a kind of employing CO
2The Big Diameter Flange surfacing equipment of gas shielded arc welding.
The technical solution adopted in the utility model is:
Adopt CO
2The Big Diameter Flange surfacing equipment of gas shielded arc welding; draw together welding cross, Big Diameter Flange, turning rolls; described Big Diameter Flange activity is located on turning rolls; in described Big Diameter Flange, be provided with welding gun; described welding gun is fixed on the cross manipulator, and described cross manipulator is fixed on the welding cross, and described welding gun connects control cabinet by welding cable; described welding gun connects wire-feed motor, and described wire-feed motor connects gas cylinder by snorkel.
Described welding gun is CO
2Gas protecting welding gun.
The utility model has the advantages that: welding cost is low, production efficiency is high, applied widely, anti-crack ability is strong, and postwelding does not need scarfing cinder, be convenient to monitoring and controlling, be conducive to realize mechanization and the automation of welding process, greatly saved human resources, welding quality is good, improve production efficiency, reduced production cost.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cutaway view of A-A of the present utility model.
Wherein: 1, welding cross, 2, Big Diameter Flange, 3, gas cylinder, 4, snorkel, 5, control cabinet, 6, welding cable, 7, wire-feed motor, 8, welding gun, 9, turning rolls, 10, the cross manipulator.
The specific embodiment
As illustrated in fig. 1 and 2, employing CO of the present utility model
2The Big Diameter Flange surfacing equipment of gas shielded arc welding; comprise welding cross 1, Big Diameter Flange 2, turning rolls 9; described Big Diameter Flange 2 activities are located on turning rolls 9; in described Big Diameter Flange 2, be provided with welding gun 8; described welding gun 8 is fixed on cross manipulator 10; described cross manipulator 10 is fixed on welding cross 1; described welding gun 8 connects control cabinet 5 by welding cable 6; described welding gun 8 connects wire-feed motor 7; described wire-feed motor 7 connects gas cylinder 3 by snorkel 4, and described welding gun 8 is CO
2Gas protecting welding gun.
By CO
2Gas protecting welding gun is clipped on cross manipulator 10, adjusts welding gun 8 positions.Big Diameter Flange 2 is positioned on turning rolls 9, and uniform rotation, guarantee that the vertical and horizontal of Big Diameter Flange 2 is at same plane.The speed of adjustment roll wheel carrier 9, after waiting Big Diameter Flange 2 rotating speeds certain, start welding.The horizontal level of fine setting welding gun 8 before being soldered together, guarantee that the second weld seam is pressed on the first weld seam.Guarantee that the concave amount between the adjacent welding bead of built-up welding two must not be greater than 1mm, between welding bead, the unevenness of lap joint must not surpass 1.5mm in the test specimen scope.
Welding cost is low.CO
2Gas is the byproduct in brewery and chemical plant, and source is wide, and price is low, thereby CO
2The cost of gas shielded arc welding only has the 40%-50% left and right of submerged-arc welding and SMAW.
Production efficiency is high.CO
2The penetration power of electric arc is strong, and fusion penetration is large and melting rate welding wire is high, so deposition rate is fast, the comparable SMAW of productivity ratio is high 1 ~ 4 times.
Applied widely.No matter which kind of position can be welded, thin plate can be soldered to 1mm left and right, the thickest unrestricted (employing multilayer welding).And welding comes speed fast compared with gas welding during thin plate, be out of shape little.
The anti-crack ability religion is strong, and the weld seam hydrogen content is low, and crack resistance is good.
Postwelding does not need scarfing cinder, is again open arc welding, is convenient to monitoring and controlling, is conducive to realize mechanization and the automation of welding process.
Greatly saved human resources, welding quality is good, has improved production efficiency, has reduced production cost.
