The large diameter flange build up welding equipment is characterized by comprising a welding cross frame, a large diameter flange and roller frames, wherein the large diameter flange is movably arranged on the roller frames, a welding gun is arranged in the large diameter welding flange, the welding gun is fixed on a cross welding operation machine, the cross welding operation machine is fixed to the welding cross frame, the welding gun is connected with a control cabinet through a welding cable, the welding gun is connected with a wire feeder, and the wire feeder is connected with a gas cylinder through a gas feeding pipe. The large diameter flange build up welding equipment has the advantages that welding cost is low, production efficiency is high, the application range is wide, crack resistance is strong, slag removing is not needed after welding, monitoring and control are convenient, achieving of mechanization and automation in a welding process is benefited, manpower resources are greatly saved, welding quality is good, the production efficiency is improved, and production cost is reduced.
Description
Technical field
The present invention relates to flange resurfacing welding equipment, relate in particular to a kind of employing CO
2The major diameter flange resurfacing welding 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 major diameter flange.And the productivity ratio of manual electric arc welding is low, the quality instability of weld metal, and outward appearance is not attractive in appearance, adopts band utmost point submerged arc Lincoln weld cost height by contrast.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in the prior art.
Summary of the invention
The purpose of this invention is to provide a kind of employing CO
2The major diameter flange resurfacing welding equipment of gas shielded arc welding.
The technical solution used in the present invention is:
Adopt CO
2The major diameter flange resurfacing welding equipment of gas shielded arc welding; draw together welding cross, major diameter flange, turning rolls; the activity of described major diameter flange is located on the turning rolls; be provided with welding gun in the described major diameter flange; 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
2The gas shielded arc welding welding gun.
Advantage of the present invention is: welding cost is low, the production efficiency height, applied widely, anti-crack ability is strong, and postwelding does not need scarfing cinder, be convenient to monitor and control, be conducive to realize mechanization and the automation of welding process, saved human resources greatly, welding quality is good, improve production efficiency, reduced production cost.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the cutaway view of A-A of the present invention.
Wherein: 1, welding cross, 2, the major 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 invention
2The major diameter flange resurfacing welding equipment of gas shielded arc welding; comprise welding cross 1, major diameter flange 2, turning rolls 9; described major diameter flange 2 activities are located on the turning rolls 9; be provided with welding gun 8 in the described major diameter flange 2; described welding gun 8 is fixed on the cross manipulator 10; described cross manipulator 10 is fixed on the 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
2The gas shielded arc welding welding gun.
With CO
2The gas shielded arc welding welding gun is clipped on the cross manipulator 10, adjusts welding gun 8 positions.Major diameter flange 2 is positioned on the turning rolls 9, and uniform rotation guarantees that the vertical and horizontal of major diameter flange 2 is on same plane.Regulate the speed of turning rolls 9, etc. major diameter flange 2 rotating speeds certain after, begin welding.The horizontal level of fine setting welding gun 8 guarantees that the second road weld seam is pressed on the first road weld seam before having welded together.Guarantee that the concave amount between the built-up welding two adjacent welding beads must not be greater than 1mm, the unevenness of lap joint must not surpass 1.5mm between welding bead in the test specimen scope.
Welding cost is low.CO
2Gas is the byproduct in brewery and chemical plant, and the source is wide, and price is low, thereby the cost of CO2 gas shielded arc welding has only about the 40%-50% of submerged-arc welding and SMAW.
The production efficiency height.CO
2The penetration power of electric arc is strong, the melting rate height of the big and welding wire of fusion penetration, 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 about 1mm, the thickest unrestricted (employing multilayer welding).And welding comes speed fast compared with gas welding during thin plate, is 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 monitor and control, is conducive to realize mechanization and the automation of welding process.
Saved human resources greatly, welding quality is good, has improved production efficiency, has reduced production cost.
