Be further used as the improvement of technical solution of the present invention, force application mechanism comprises the support bar and the brake block hinged with the lower end of support bar that are stretched out by support arm downwards, the downside of brake block arranges force-application block in the front of support bar, and brake block is provided with and drives brake block rotate around the pin joint with support bar and press the force-applying piece of force-application block downwards.
Be further used as the improvement of technical solution of the present invention, force-applying piece is the hydraulic cylinder being connected to support arm or support bar by the upper end of brake block.
Be further used as the improvement of technical solution of the present invention, force-application block is rolling wheel.
Present invention also offers a kind of method utilizing said apparatus to improve weld seam form and performance, comprise the following steps:
A. according to the product requirement of submerged-arc welded (SAW) pipe, suitable welding parameter is selected;
B. move welding gun and carry out submerged-arc welded (SAW) pipe welding, and use the force-application block of weld seam force application apparatus to carry out pressing exert a force to being in liquid or semi-solid weld seam;
C. liquid or semi-solid weld seam force-application block forming under the pressure, solidify, obtain desirable weld seam form.
Be further used as the improvement of technical solution of the present invention, be welded as submerged-arc welding.
Beneficial effect of the present invention: in submerged arc welding process, force-application block in weld seam force application apparatus applies pressure to the weld seam being still in liquid state or semisolid stage, liquid state or semisolid weld seam is made to produce plastic deformation by the surface configuration of force-application block, produce liquid forging effect, after forging and stamping, weld seam inner homogeneous is fine and close, eliminate the defect that weld seam may exist, improve the ballistic work of Weld pipe mill and heat affected area, and the form of weld seam can be controlled, reduce weld grinding amount, the weld seam form that the present invention solves submerged-arc welded (SAW) pipe is very well difficult to control, may the problems such as critical defect be there is in weld seam.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is weld seam force application apparatus structural representation of the present invention;
Fig. 2 is using state schematic diagram of the present invention.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, the invention provides a kind of weld seam force application apparatus, the force-application block 2 comprising support arm 1 and be positioned at below support arm 1, support arm 1 is provided with the force application mechanism 3 of pressing force-application block 2 downwards.
As the preferred embodiment of the invention, force-application block 2 is preferably rolling wheel (certain force-application block 2 also can adopt briquette form), carry out in the welding process of interior outside weld at submerged-arc welded (SAW) pipe 6, rolling wheel in weld seam force application apparatus applies pressure to the weld seam being still in liquid state or semisolid stage, liquid state or semisolid weld seam is made to produce plastic deformation by the surface configuration of rolling wheel, produce liquid forging effect, after forging and stamping, weld seam inner homogeneous is fine and close, eliminate the defect that weld seam may exist, improve the ballistic work of Weld pipe mill and heat affected area, and the form of weld seam can be controlled, reduce weld grinding amount, the weld seam form that the present invention solves submerged-arc welded (SAW) pipe is very well difficult to control, may the problems such as critical defect be there is in weld seam.
As the preferred embodiment of the present invention, force application mechanism 3 comprises the support bar 31 and the brake block 32 hinged with the lower end of support bar 31 that are stretched out by support arm 1 downwards, the downside of brake block 32 arranges force-application block 2 in the front of support bar 31, and brake block 32 is provided with and drives brake block 32 rotate around the pin joint with support bar 31 and press the force-applying piece of force-application block 2 downwards.
As the preferred embodiment of the present invention, force-applying piece is the hydraulic cylinder 4 being connected to support arm 1 or support bar 31 by the upper end of brake block 32.
The operation principle of the present embodiment is: brake block 32 is a gore, hydraulic cylinder 4, rolling wheel and be positioned at three angle points of brake block 32 with the pin joint of support bar 31, and hydraulic cylinder 4 is obliquely installed.When needs by rolling wheel to be in liquid or semi-solid weld seam rolls force time, be placed in by rolling wheel above weld seam, hydraulic cylinder 4 extends, and drives brake block 32 to rotate counterclockwise around the pin joint with support bar 31, so makes rolling wheel move downward compacting weld seam.
