For submerged arc welding of an outer arc surface or an outer spherical surface, as shown in fig. 1 and 2, the invention provides an auxiliary tool for blocking welding flux in submerged arc welding, which comprises a flux feeding pipe fitting and a fixing frame, wherein the flux feeding pipe fitting is detachably connected with a welding gun head 1, and the flux feeding pipe fitting is provided with a pipeline for conveying the welding flux to the bottom of the welding gun head 1; the fixing frame is sleeved outside the welding flux feeding pipe fitting and detachably connected with the welding flux feeding pipe fitting, the fixing frame comprises a U-shaped frame body 4 perpendicular to the welding gun head 1, the U-shaped frame body 4 is clamped with the welding flux feeding pipe fitting, the U-shaped frame body 4 is provided with a striker plate 9 for blocking welding flux from falling, the striker plate 9 is not shown in fig. 1, and the striker plate 9 is shown in fig. 2.
Specifically, the working principle of the invention is that a welding flux feeding pipe fitting is connected with a fixing frame, and when welding flux falls below a welding gun head 1, a stop plate 9 of the fixing frame can enable the welding flux to stay right below the welding gun head 1. Taking the side of a welded barrel as an example, the barrel is laterally placed, and the barrel is driven to rotate along the circumferential direction by external equipment, the side of the barrel is a cambered surface, when the welding gun head 1 is positioned on the side of the barrel, the welding flux can slide down from the side of the barrel due to the driving action of the rotation of the barrel and the gravity of the welding flux, and the submerged arc welding effect is poor.
According to the invention, the dam 9 is positioned in front of the rotation direction of the barrel body, the height of the dam 9 is adjusted to enable the dam 9 to be as close to the side face of the barrel body as possible, the highest point of the side face of the barrel body is not positioned by the gun head 1 in consideration of the gravity action of welding flux and the driving action of the barrel body rotation on the welding flux, the falling direction of the welding flux due to the gravity action is consistent with the falling direction of the barrel body rotation on the driving action of the welding flux, as shown in fig. 1, at the moment, the bottom end of the dam 9 is positioned at the lowest point, and all welding flux on the side face of the barrel body is blocked by the dam 9.
Further, the welding flux feeding pipe piece comprises a welding gun connecting pipe 2 and a feeding pipe 3, the welding gun connecting pipe 2 is sleeved outside the welding gun head 1, a locking bolt 12 is arranged at the top end of the side face of the welding gun connecting pipe 2 and used for locking the welding gun connecting pipe 2 at a welding gun position, the welding gun head 1 is exposed at the bottom end of the welding gun connecting pipe 2, the welding gun connecting pipe 2 is clamped in the U-shaped frame body 4, the feeding pipe 3 is obliquely communicated with the welding gun connecting pipe 2, and the feeding pipe 3 is communicated with a welding flux feeding pipeline and used for conveying welding flux to the position right below the welding gun head 1.
And the fixing frame also comprises a positioning bracket 5 of an inverted U shape, the bottom ends of the positioning bracket 5 are respectively connected with the two ends of the U-shaped frame body 4, the positioning bracket 5 is hung between the welding gun connecting pipe 2 and the feeding pipe 3, and the welding gun connecting pipe 2 is positioned between the positioning bracket 5 and the U-shaped frame body 4 and used for stably hanging the U-shaped frame body 4 on a welding flux feeding pipe fitting and moving along with the movement of a welding gun.
The positioning bracket 5 is used for fixing the U-shaped frame body 4 on the flux feeding pipe fitting and moving along with the movement of the flux feeding pipe fitting. Because an included angle exists between the welding gun connecting pipe 2 and the feeding pipe 3, and the positioning bracket 5 uses the included angle to act as a hanging point, as can be seen from fig. 1, the welding gun connecting pipe 2 actually passes through a space enclosed between the positioning bracket 5 and the U-shaped frame body 4, so that the positioning bracket 5 also has the function of limiting the welding gun connecting pipe 2.
Further, at least one auxiliary positioning rod 6 extending horizontally is arranged on the side face of the positioning support 5, the auxiliary positioning rod 6 is located on the outer side of the feeding pipe 3, a positioning nut is arranged at the outer end of the auxiliary positioning rod 6, a positioning screw 7 is screwed into the positioning nut, and the fixing frame is firmly locked outside the welding flux feeding pipe piece through the positioning support 5, the positioning screw 7 and the U-shaped frame body 4. Preferably, the number of the auxiliary positioning rods 6 is two, the two auxiliary positioning rods 6 are symmetrically arranged on two sides of the positioning support 5, and the positioning screw 7 is in threaded connection with two positioning nuts to firmly lock the fixing frame outside the welding flux feeding pipe.
As can be seen from fig. 1, since the feed pipe 3 is obliquely disposed, the positioning screw 7 and the positioning bracket 5 cannot move along the direction of the feed pipe 3, specifically, it is assumed that when the whole fixing frame moves upward along the feed pipe 3, the U-shaped bracket body 4 contacts with the welding gun connecting pipe 2 to limit the fixing frame to move rightward, that is, the right side of the view direction of fig. 1, and the positioning screw 7 contacts with the feed pipe 3 to limit the fixing frame to move upward, and therefore, the fixing frame is firmly locked outside the flux feed pipe by the cooperation of the positioning screw 7, the positioning bracket 5 and the U-shaped bracket body 4, and the fixing frame cannot be loosened from the flux feed pipe in the submerged arc welding process.
As shown in fig. 2, a U-shaped clamping hole 13 is formed in the U-shaped frame 4, the striker plate 9 is a flame-retardant soft rubber plate, the length of the striker plate 9 is greater than or equal to the total length of the clamping hole 13, and the striker plate 9 is inserted into the clamping hole 13, so that the striker plate 9 is fixed in the U-shaped frame 4. The inner wall of the clamping hole 13 is further provided with a pressing block 10 for pressing the striker plate 9, a pressing spring 11 is arranged between the pressing block 10 and the inner wall of the clamping hole 13, and the outer side of the U-shaped frame body 4 is provided with a fixed baffle plate 8 for preventing the striker plate 9 from inclining.
It is easy to understand that when the length of the striker plate 9 is greater than or equal to the total length of the clamping hole 13, the striker plate 9 may be clamped in the clamping hole 13. In order to firmly connect the striker plate 9 with the U-shaped frame body 4, the striker plate 9 is pressed in the clamping hole 13 through the pressing block 10.
It should be noted that, the pressing block 10 is disposed at the bottom end of the U-shaped frame 4 and is located on the upper inner wall of the clamping hole 13, i.e. in the view direction of fig. 2.

During welding, the welding machine falling from the welding gun connecting pipe 2 is blocked by the striker plate 9, the flux stays on the welding surface, and the welding gun performs submerged arc welding operation.
It should be noted that, during welding of the extrados or the extrados, the position of the welding gun head 1 should not be at the highest point of the extrados or the extrados, and be at a position slightly lower than the highest point, and the direction of the stop plate 9 should be at the rear end of the welding gun moving direction, and the lowest point of the stop plate 9 should be lower than the welding gun head 1, or be level with the lowest point of the welding gun head 1, so as to prevent the welding flux from sliding off as much as possible, taking the side of the welding barrel as an example, and taking the view direction of fig. 1 as an example, the barrel rotates anticlockwise, the welding gun is located at the left side of the highest point, and when the barrel rotates, the welding gun moves rightwards on the side of the barrel, then the stop plate 9 should be arranged at the left side of the welding gun, and under the action of gravity and the driving action of the rotation of the barrel, the welding flux can slide leftwards, and at this moment the stop plate 9 can play the role of preventing the welding flux from sliding off.
