Abstract
The utility model relates to an arc-striking steel fiber, which belongs to a steel fiber used in electric welding. The dimension of the steel fiber is smaller. When collected into an agglomerate, the steel fiber is like cotton. The steel fiber has the advantage of good conductivity, and can be burnt when the steel fiber meets open fire or passes through large current. The agglomerate steel fiber is arranged between a beveling of a steel sheet and a welding wire, a welder is started, and the steel fiber is very easily ignited under the action of the normal working current of the welding wire. After ignition, an arc between the welding wire and the steel sheet is pulled up, the arc striking is very easy. Starting current is as same as the normal welding current. No welding beading is produced at an igniting position. A weld seam is smooth and beautiful, and as same as the normal welding part.
Description
The utility model relates to the steel fibre that uses in a kind of electric welding, particularly a kind of striking steel fibre.
At present, people are when electric welding, particularly when using automatic arc welding, be on steel plate, to accomplish fluently groove, put into a base plate in the bottom of groove, then welding wire is connected with the groove place of steel plate, welding wire is connected with electric welding machine, starts electric welding machine, can implement the welding to steel plate, need be after welding wire and the striking of weldment position before the welding, just can carry out normal welding job, general striking is that welding wire contacts with workpiece, and moment dash electric current makes welding wire end [molten metal explosion formation space starting arc under the effect of weldingvoltage during by " starting ", when the welding wire of this situation explosion was big, entering fusing can influence weldquality; When the feed rate of welding wire is big repeatedly explosion phenomenon can take place, prolong the striking time.Automatically mention when another kind of striking is the welding wire " starting " that makes contact workpiece and excite electric arc, if being is arranged, a bit of welding wire is normally cut off in just very striking when striking between this situation welding wire and workpiece, the non-cutting time of increase striking.The thinnest section of welding wire that uses on the general automatic welder(welding machine) must not be less than 3 millimeters, starting current is big when adopting this welding wire to implement welding, be not easy to ignite, even ignite successfully, its back of igniting easily produces bigger overlap at the position of igniting, one comes not attractive in appearancely, and two come connection welding insecure, influence welding quality.
The purpose of this utility model is that the striking steel fibre that a kind of starting current is little, ignite easily will be provided.
The purpose of this utility model is achieved in that steel fibre is of a size of 0.1 millimeter-0.0001 millimeter.
Owing to adopted such scheme, the size of steel fibre is less, gather similar cotton when agglomerating, incendivity when naked light is arranged, agglomerating steel fibre is placed between the groove and welding wire of steel plate, start electric welding machine, because steel fibre is between weldment and the welding wire, the electric current of electric welding machine arrives on the weldment by steel fibre, because the effect that steel fibre very easily burns, the welding current of moment ignites steel fibre, and electric arc will get up by automatic combustion, very easily striking, and starting current is identical with normal welding current, and does not have overlap to produce at the position of igniting, and is identical with normal weld, there are not the explosion of welding wire and striking repeatedly, also do not need to cut off one section welding wire, the weldquality when both having guaranteed striking has also shortened the striking time, has simplified operation greatly, save electric energy, reached the purpose of this utility model.This steel fibre size is less, places between the groove and welding wire of steel plate, and very easily striking, the weldquality when promptly having guaranteed striking has also shortened the striking time, the smooth welding joint of striking place, attractive in appearance, welding quality is good, has produced beyond thought effect.
Be described further in conjunction with the embodiments with reference to the accompanying drawings below.
Accompanying drawing is working state structure figure of the present utility model.
Embodiment: on steel plate 1, accomplish fluently groove, put into a base plate 4 in the bottom of groove, put into steel fibre 2 at the groove place of welding wire 3 and steel plate 1 then, welding wire 3 is connected with electric welding machine, start electric welding machine, because steel fibre is of a size of 0.1 millimeter, and conduct electricity very well, under the effect of welding wire running current, the welding current of moment ignites steel fibre, more little easy more the igniting of the size of steel fibre 2, electric arc will get up by automatic combustion, very easily ignite, the back of igniting is about to the electric arc pull-up between welding wire and the steel plate, can implement the welding to steel plate 1, weldquality when promptly having guaranteed striking has also shortened the striking time, the smooth welding joint of striking place, attractive in appearance, welding quality is good, has produced beyond thought effect.
