Description
Technical field
The utility model relates to a kind of submerged-arc welding contact tube, and particularly a kind of have the submerged-arc welding contact tube correcting arc blow function.
Background technology
In the docking welding of heavy thickness weldment, narrow gap welding is a kind of high-quality and efficient process beyond doubt.But use this process, particularly when bevel for welding root pass, due to this portion structure often more complicated (as: have gap to cause structure discontinuous, misalignments etc. cause shape sudden change etc.), and be subject to the link position of welding circuit cable and weldment and the impact of other environment, the electromagnetic field that this place produces in welding process is not continuous and stable (yet can the interruption thinking to create the magnetic line of force of image and distortion), makes electric arc in the process of welding root pass, be easy to generation arc blow.Along with the generation of arc blow, deposited metal is deposited on the sidewall of groove, can cause the weld defects such as pore, slag inclusion, incomplete fusion, could continue welding after must removing.But because groove is narrow and dark, particularly can not the situation of back gouging for weldment, carry out reprocessing extremely difficult, very time-consuming.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of arc protection arc blow submerged-arc welding contact tube, for solving the problem of heavy thickness narrow gap welding root pass arc blow.
In order to solve this technical problem, the utility model by the following technical solutions:
A kind of arc protection arc blow submerged-arc welding contact tube, comprises ignition tip main body, it is characterized in that: the relative both sides of described ignition tip main body offer a resettlement groove respectively, and are respectively provided with one piece of strong magnets in two resettlement grooves.
Described strong magnets is the strong magnets of monopole magnetism; The shielding end of strong magnets is positioned at resettlement groove, and magnetic pole is outside resettlement groove.
Strong magnets in the resettlement groove of both sides and ignition tip body ends distance are not etc.
Ignition tip main body upper end, with connecting thread, connecting thread is provided with back tightening nut.
Also comprise and be wound around and stick to the High temperature-resistanadhesive adhesive tape of ignition tip body outer surface.
Good effect of the present utility model is:
By arranging strong magnets on narrow-clearance submerged arc welding ignition tip, carry out interference to Narrow sloping-glot root weld electric arc electromagnetic field to control, guarantee effectively to correct arc blow, thus avoid consequent weld defect and Weld Seam Repairation, improve welding quality and work efficiency.High temperature-resistanadhesive adhesive tape can guarantee that the operating temperature of magnet is in allowed band, makes magnet in normal weld, have good magnetic; Also significantly reduce the operating temperature of ignition tip, extend its service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the structural representation of the utility model embodiment two.
Detailed description of the invention
The utility model is further illustrated below in conjunction with drawings and Examples.
Embodiment one
As shown in Figure 1, the present embodiment comprises ignition tip main body 3, and ignition tip main body 3 upper end, with connecting thread 1, connecting thread 1 is provided with back tightening nut 2, ignition tip main body 3 lower end with wear-resistant block 5, described wear-resistant block 5 is high by hardness, good conductivity again resistant to elevated temperatures material make.
The transversal face width side of described ignition tip main body 3 is 25mm, and narrow side is 8mm, and the length of main body is 280mm.Such structure is the needs for adapting to narrow gap.
The relative both sides of ignition tip main body 3 offer a resettlement groove 4 respectively, and in two resettlement grooves 4, are respectively provided with one piece of strong magnets, i.e. top strong magnets 7 and bottom strong magnets 6.Described resettlement groove 4 position, near ignition tip main body 3 lower end, hits exactly in the wide side of ignition tip main body 3.Magnet resettlement groove 4 length is 100mm, and the degree of depth is 0.5mm, and distance ignition tip lower end, lower end is about 30mm, and width and strong magnets diameter matches, be generally 5mm.The object arranging magnet resettlement groove 4 is convenient to strong magnets can freely up and down adjust and centering.
Described connecting thread 1 is supporting with submerged arc welding machine head ignition tip connecting thread, and longer than the screw thread of original ignition tip, and length is 45mm.When being connected with head by the utility model ignition tip, screw thread is not screwed into the end, but by after being threaded into suitable length, after adjustment ignition tip to duty, fastening with back tightening nut 2.
Described strong magnets is neodymium iron boron strong magnets, and maximum operating temperature is 230 DEG C.Shielding processing to be carried out to the N pole of strong magnets or S pole carbon steel plate before using, make it show monopole magnetism S pole or N pole.The specification of two strong magnets used is identical with polarity.What strong magnets adopted is cylinder-shaped magnet, diameter 4mm, height 3.5mm.Its occupation mode puts into resettlement groove 4 for shielding end.First the strong magnets of side is positioned at the position that distance ignition tip end is nearer, in the present embodiment, is specially 40mm; Opposite side strong magnets distance ignition tip end is comparatively far away, and particular location will according to weldment thickness, and groove root situation suitably adjusts, and in the present embodiment, distance end is 60mm.
Upper and lower strong magnets height staggers, object is that bottom strong magnets 6 is near apart from electric arc, can than stronger to the interference of electromagnetic field, play the effect of matching coordinative by top strong magnets 7 pairs of bottom strong magnets 6, both sides magnet plays the correction effect to electric arc jointly.
Embodiment two
As Fig. 2, the present embodiment increases High temperature-resistanadhesive adhesive tape 8 on the basis of embodiment one.Described High temperature-resistanadhesive adhesive tape 8 is tightly wound around equably and sticks to ignition tip main body 3 outer surface.
The width of selected High temperature-resistanadhesive adhesive tape 8 is 25mm, ignition tip is wound around adhere to time, be often wound around the overlap joint that a circle will enclose with upper a 5mm that has an appointment, require all standing, stop leakage to twine and space.Require that the heat resistance of adhesive tape reaches 260 DEG C.High temperature-resistanadhesive adhesive tape 8 can effectively be carried out high temperature and be covered, can ensure that brute force can not produce demagnetization because temperature is too high, the position of strong magnets can be fixed again, effectively can also reduce the serviceability temperature of ignition tip entirety 3, thus strengthen its wearability, extend its service life.
Following problem to be noted: when using arc protection arc blow submerged-arc welding contact tube to find that there is arc blow phenomenon in welding process when using the utility model, stop welding, first the measure taked is unclamped by back tightening nut, and ignition tip is rotated 180 °, again fastening rear continuation welding.So generally have good effect, and flexible and convenient operation.Secondly according to the concrete condition producing arc blow, the position of two magnet is readjusted.
