Specific embodiment
Preferred embodiment is enumerated below, and completely illustrates the present invention in conjunction with attached drawing to become apparent from.
As shown in figure 4, the present invention provides a kind of thick plate steel FCAW weldering groove process ruler, 3 shape of technique ruler ontology is sector,
Technique ruler scale 36 is set on technique ruler ontology 3, is provided with appearance of weld coefficient in the measurement end 31 of technique ruler ontology 3 and controls head
32, the shape that appearance of weld coefficient controls head 32 is arc, is provided with horizontal tube 34 on handheld terminal 33.In technique ruler ontology 3
Handheld terminal 33 install horizontal tube 34, be in order to prevent measurement when technique ruler relative to the angle on the horizontal and vertical direction of groove face
Degree has deviation, becomes smaller so as to cause bevel angle.
Thick plate steel FCAW welds groove process ruler and is used in the FCAW welding of thick plate steel, as shown in Figure 1, the slope of this thick plate steel
Mouth-shaped is double V groove 1, and the thickness δ of this thick plate steel is 80mm, and the group of double V groove 1 is 10mm to gap.This thick plate steel
Welding sequence be, first will the first welding surface preheating after carry out FCAW welding, after welding using carbon arc air gouging to the second welding surface
14 back chippings modify groove, polish, and preheat after groove finishing is qualified to the second welding surface 14, then carry out FCAW weldering
It connects.
When carrying out the welding of the second welding surface 14, semi-automatic FCAW welding gun will be swung, as shown in Figures 2 and 3, when half from
When nozzle 21 on the head 2 of dynamic FCAW welding gun swings to the first supporting point 18, what welding wire 23 touched double V groove 1 second is connect
On contact 17, when the nozzle 21 on the head 2 of semi-automatic FCAW welding gun swings to the second supporting point 19, welding wire 23 touches X
On the first contact point 16 of shape groove 1.First supporting point 18, the second contact point 17 and the second supporting point 19, first contact point 16
Form a sector, the maximum angle that fan-shaped angle can swing for semi-automatic FCAW welding gun.Welding wire during swing
23 to be formed by camber line and appearance of weld coefficient control head 32 identical.
The central angle of technique ruler ontology 3 is contacted with the first supporting point 18, the second contact point 17 and the second supporting point 19, first
The maximum angle that the angle that point 16 is formed can swing for semi-automatic FCAW welding gun is identical, that is, the angle of double V groove 1.Work
Skill ruler ontology 3 with a thickness of 2mm, its material is corrosion resistant stainless steel.
Since FCAW welds narrow groove, larger value of forming coefficients can be obtained using lesser welding parameter, one
As it is desirable that obtain forming coefficients≤1.1mm, welding fabrication coefficient=single pass welding fusion penetration/single pass welding width, it is desirable that
The distance between one contact point 16 and the second contact point 17 are not less than 10mm, that is to say, that in the measurement end 31 of technique ruler ontology 1
Chord length be not less than 10mm.
And the groove depth of the second welding surface 14 is not less than 1/2 δ+10mm, that is, 50mm, therefore maximum scale 38 is not small
In 50mm.In measurement, technique ruler has deviation relative to the angle on 1 vertical and horizontal of double V groove and causes groove in order to prevent
Angle becomes smaller, therefore horizontal tube 34 is installed on handheld terminal 33.It carries for the convenience of the users, key is provided on handheld terminal 33
Keyhole facilitates installation key ring or rope band.
When modifying the groove of the second welding surface 14, measured with thick plate steel FCAW weldering groove process ruler, if groove does not conform to
It is suitable to continue to modify, until welding groove is matched with thick plate steel FCAW weldering groove process ruler.It can will thus weld slope
Mouth quantization and standardization, improve weld seam internal soundness, reduce cost.
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that this is only
For example, protection scope of the present invention is to be defined by the appended claims.Those skilled in the art without departing substantially from
Under the premise of the principle and substance of the present invention, many changes and modifications may be made, but these change and
Modification each falls within protection scope of the present invention.
