Abstract
Provided is an arc striking device of a stainless steel pipe straight seam welding end. The arc striking device of the stainless steel pipe straight seam welding end is simple in structure and convenient to operate, and improves welding quality. The arc striking device comprises an arc sheet-shaped arc striking plate, and the protruding arc surface of the arc striking plate is adaptive to the arc shape of the inner surface of a stainless steel pipe. The arc sheet-shaped arc striking plate adaptive to the stainless steel pipe is added to the stainless steel pipe straight seam welding end, through the function of the arc striking plate, straight seam welding is transmitted, and the welding quality is improved. A sinking arc locating step surface is formed on the arc striking plate to enable the location and connection with the stainless steel pipe to be convenient. Meanwhile, an arc striking groove is formed in the protruding arc surface of the arc striking plate, the butt joint with a straight seam is achieved, and the smoothness and reliability of arc striking are improved. The arc striking plate is installed through clamp forceps, can be dismounted and used repeatedly, and is convenient to operate. The arc striking device of the stainless steel pipe straight seam welding end guarantees the welding quality, and improves production efficiency.
Description
Technical field
The utility model relates to welding technology field, relates in particular to the striking servicing unit of stainless steel tube termination vertical masonry joint welding.
Background technology
Striking occupies an important position in welding process, and can striking performance quality directly have influence on welding process and carry out smoothly.In the prior art, when stainless steel tube welded in the vertical masonry joint termination, as shown in figure 11, owing to manually wait operation, occurring the termination easily burnt breakage etc., causes the stainless steel tube termination breach 5 to occur, has influenced weldquality; In the factory, in order to obtain the section of weld joint of normal size at welding top, termination, to assemble a metallic plate before the weldering usually.By hand a sheet material is spoted weld earlier an end of the welded seam of wanting before the welding, begin striking from this piece plate then, when the weld seam of required processing, the weldquality of this moment welding is relatively good, and defective is few, wait welding to finish after, again this plate is sliced off, in use, increase material consumption, caused the wasting of resources; Simultaneously, because cutting need polish otch, increase follow-up process, made production efficiency low.
The utility model content
The utility model provides a kind of simple in structure, easy to operate at above problem, improves the stainless steel tube vertical masonry joint welding termination arc initiation device of welding quality.
The technical solution of the utility model is: described arc initiation device comprises the run-on tab that is circular arc sheet, and the arc of the protrusion cambered surface of described run-on tab and the inner surface of described stainless steel tube is suitable.
The protrusion cambered surface of described run-on tab offers the arc positioning table terrace of sinking towards the direction of described stainless steel tube, is used for the inner surface of described stainless steel tube is shelved on described arc positioning table terrace.
Offer the striking groove coaxial with described vertical masonry joint on the protrusion cambered surface of described run-on tab.
End face at described run-on tab is provided with a pair of clamp, and described a pair of clamp lays respectively at the both sides of described vertical masonry joint, makes described run-on tab be detachably connected on the described stainless steel tube.
Arc initiation device has increased the run-on tab with the suitable circular arc sheet of stainless steel tube in the utility model in stainless steel tube vertical masonry joint welding termination, by the effect of run-on tab, carries out the transition to the vertical masonry joint welding, has improved welding quality; Offer the arc positioning table terrace of sinking at run-on tab, made things convenient for the location of stainless steel tube be connected; Simultaneously, offer the striking groove in the protrusion cambered surface of run-on tab, realized and the docking of vertical masonry joint, improved fluency and the reliability of striking.Run-on tab is installed by clamp, and detachable the repeated use is easy to operate.The utility model has guaranteed weldquality, has improved production efficiency.

The specific embodiment
The utility model is shown in Fig. 1-10, and described arc initiation device comprises the run-on tab 2 that is circular arc sheet, and the arc of the protrusion cambered surface of described run-on tab 2 and the inner surface of described stainless steel tube 1 is suitable.
The protrusion cambered surface of described run-on tab 2 offers the arc positioning table terrace 20 of sinking towards the direction of described stainless steel tube 1, is used for the inner surface of described stainless steel tube 1 is shelved on described arc positioning table terrace 20.
Offer the striking groove 4 coaxial with described vertical masonry joint 10 on the protrusion cambered surface of described run-on tab 2, improved the continuity of striking action.
End face at described run-on tab 2 is provided with a pair of clamp 3, and described a pair of clamp 3 lays respectively at the both sides of described vertical masonry joint 10, makes described run-on tab 2 be detachably connected on the described stainless steel tube 1, and convenient the repeated use saved material.
In actual applications, welding gun 6 carries out the transition to the vertical masonry joint 10 on the stainless steel tube earlier through the striking groove 4 on the run-on tab 2, has guaranteed the welding quality of stainless steel tube termination.
