The automatic welding start button 24 of weldering, PLC controls the actuating of relay and starts to weld at this time, if welding is completed, PLC controller 8 makes steel
Bar stops rotating, welding gun stops mobile, cutting welding gun power supply and stops wire feed.If rod iron material rotation speed is n (unit r/
Min), weld spacing should be less than the width of weld seam 37, if weld spacing is L0(unit mm), the length of rod iron material 34 are L
(unit mm), the diameter of rod iron material 34 are D (unit mm), then can calculate rod iron material 34 and revolve the time t=to turn around
60000/n (unit ms), speed v=1000 × L that welding-torch horizontal direction moves left and right0/ t (unit mm/s), welding gun from
Rod iron material head end 36 is moved to the time t of rod iron material end 381=(L-L0(unit s) is welded to)/v from rod iron material head end 36
The total time t of end 382=t1+2×t.In order to make 34 outer wall of rod iron material wrap up in full stainless steel, need back and forth to weld several times, reciprocal weldering
It connects number to be arranged according to welding experience, it is assumed that reciprocal welding times are x.According to above-mentioned calculating and description, the tool of automatic submerged arc welding
Body process is：(1) welding gun 35 is moved to weld start position, i.e., at rod iron material head end 36, welding gun 35 is remained stationary；(2) at the uniform velocity
Rod iron material 34 is rotated, along 34 outer wall of rod iron material welding, one circle, required time t；(3) then welding gun 35 starts with speed v to steel
Bar end 38 is mobile, while rod iron material 34 remains a constant speed rotation, is t the time required to this process1；(4) then welding gun 35 reaches
At rod iron material end 38, welding gun 35 is kept to stop movement at this time, rod iron material 34 at the uniform velocity rotates, and full one is welded at rod iron material end 38
There is weld seam as shown in Figure 5 in rod iron material outer wall at this time in circle, required time t；(5) welding gun 35 starts with speed v from rod iron
Expect to the movement of rod iron material head end 36 at end 38, while rod iron material 34 at the uniform velocity rotates, this process used time is also t1, so complete the
Primary reciprocal welding；(6) adjust automatically weld start position, i.e., by welding gun 35 from the initial position of last time welding to rod iron material
End direction at the uniform velocity moves half weld spacing L0, (2)-(5) welding process is then repeated, so by the reciprocal of setting
Welding times complete the submerged-arc welding of entire 34 outer wall of rod iron material.
Rod iron material gas shielded arc welding and submerged-arc welding automatic control system of the invention be adaptable, high reliablity, automation
Degree is high, and adding control system of the present invention in gas shielded arc welding and the equipment of submerged-arc welding can be improved the whole of welding technique
