Abstract
The invention relates to welding equipment, in particular to a welding device for an internally-clad stainless steel tube of a clad steel plate. The welding device comprises an MIG welding power source, an automatic wire feeder and an MIG welding gun. The MIG welding gun is mounted on a three-dimensional gun rack through a gun clamp, and the three-dimensional gun rack is mounted on a welding gun support. Sizing rolls are mounted below the MIG welding gun, and a welding fixture is mounted between the sizing rolls. One end of the welding fixture is mounted on a welding support, a steel tube to be welded enters the welding fixture from a straight-seam tube manufacturing production line and enters the position between the sizing rolls, and the steel tube is welded by the MIG welding gun. The welding device for the inner composite stainless steel tube of the clad steel plate is in butt joint with a common straight-seam tube manufacturing production line or a spiral tube manufacturing production line, open arc automatic welding is conducted from the outer surface of the steel tube, one-time welding is achieved, and the welding quality and the production efficiency are improved. Weld joint single-face welding and double-face forming of dissimilar metal welding are achieved. The quality of a welding joint is improved, particularly, the weld microstructure of a stainless steel composite layer face achieves two-phase organization, and therefore the corrosion resistance is better than that of a base material.
Description
Technical field
The present invention relates to a kind of welding equipment, be specially multiple stainless steel tube welder in clad steel plate.
Background technology
Domestic current carbon steel-stainless steel clad steel plate has realized batch production, wherein multiple stainless steel tube in clad steel plate, internal layer is stainless steel, account for about 17% of clad steel plate total thickness, skin is carbon steel material, interior multiple stainless steel tube is divided into ERW and spiral welded pipe two class by manufacturing process, and its equipment used is respectively vertical masonry joint tubulation production line and spiral tubulation production line.
Interior multiple stainless steel ERW, current domestic welding method is all unsuccessful.Problem is that plumb joint is different steel weld, can only be again to weld from tube outer surface, causes interior multiple stainless steel weld joint decay resistance defective.
For the welding of interior multiple stainless steel ERW, generally believe at present, interior multiple stainless steel tube cannot accomplish forming a solder, because diameter is general comparatively large, some domestic at present enterprises adopt inside and outside twice welding method tubulation, and interior multiple stainless steel weld joint first welds, weld after outer carbon steel, it is welding heat affected to first welding line, makes stainless steel weld joint degradation, also causes decay resistance defective.
Summary of the invention
For above-mentioned technical problem, the invention provides the welding equipment that a kind of technique is simple, weld seam corrosion resistance is high, for the welding of stainless steel tube multiple in clad steel plate, concrete technical scheme is:
In clad steel plate, multiple stainless steel tube welder, comprises the MIG source of welding current, automatic wire feeder, welding gun bearing, three-dimensional gun rack, MIG welding gun, welding tooling, welding bearing, size rolls; Described MIG welding gun is arranged on three-dimensional gun rack by rifle folder, described three-dimensional gun rack is arranged on welding gun bearing, described size rolls is arranged on below MIG welding gun, between the roller that welding tooling is arranged on size rolls, welding tooling one end is arranged on welding bearing, steel pipe to be welded enters welding tooling from vertical masonry joint tubulation production line, enter between size rolls, welded by MIG welding gun.
Multiple stainless steel tube welder in clad steel plate provided by the invention, with common vertical masonry joint tubulation production line or or spiral tubulation production line dock, carry out open arc automatic welding from outer surface of steel tube, once weld, raising welding quality and production efficiency; Realize the weld seam one side welding with back formation of different-metal material welding; The seam organization of quality of weld joint especially stainless steel double aspect obtains duplex structure, thus makes decay resistance be better than mother metal.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Accompanying drawings the specific embodiment of the present invention, as shown in Figure 1, multiple stainless steel tube welder in clad steel plate, comprises the MIG source of welding current 1, automatic wire feeder 2, welding gun bearing 3, three-dimensional gun rack 4, MIG welding gun 5, welding tooling 6, welding bearing 7, size rolls 8; Described MIG welding gun 5 is arranged on three-dimensional gun rack 4 by rifle folder, described three-dimensional gun rack 4 is arranged on welding gun bearing 3, described size rolls 8 is arranged on below MIG welding gun 5, between the roller that welding tooling 6 is arranged on size rolls 8, welding tooling 6 one end is arranged on welding bearing 7, steel pipe 9 to be welded enters welding tooling 6 from vertical masonry joint tubulation production line, enter between size rolls 8, welded by MIG welding gun 5.
On common vertical masonry joint tubulation production line, equipped clad steel plate answers stainless steel tube welder outward, and MIG welding gun 5 carries out top to bottom, left and right, front and rear three-dimensional adjustment by three-dimensional gun rack 4, and can rotate the angle of adjustment MIG welding gun 5 according to welding requirements.Erecting and welding frock 6 between the size rolls 8 rolling joint close section, welding tooling 6 stretches in steel pipe 9 to be welded, can carry out automatic welding, realize one side and once weld two-sides forming after starting welding.
