Problems solved by technology

Glass tube barometer measurement generally uses a water-cooled copper plate with holes as a test block, which not only cannot reflect the relationship between the actual welding material and the arc, but also has a certain impact on the arc due to small holes

Start reading when the cross laser on the scale 18 tends to be stable, and record the ...

Embodiment 2

[0049] The test supporting plate 3 is made of Q235 steel plate, the welding parameters of argon tungsten arc welding are shown in Table 1, and the elastic stiffness of the spring 7 is selected as 0.1N / mm. The main component of the active agent is TiO 2 ,Cr 2 o 3 ,ZrO 2 and CaF 2 Wait. Before the test, the active agent powder was mixed into a solution with acetone, and then evenly coated on the support plate 3 with a flat brush, and the uniformity of the coating was ensured as much as possible during the coating process. In the test L, l 1 , l 2 All unchanged, the device is in a balanced state by the counterweight 2. The initial reading A on the scale 18 at this time 1 It is 153mm. Turn on the argon tungsten arc welding power supply, adjust the welding parameters for welding. Start reading when the cross laser on the scale 18 becomes stable, and record the reading A at this time 2 It is 224mm. From tanδ=(Δ) / L, tanδ=Δ′ / l 1, The variation Δ' of the spring is obtained...

Abstract

The invention discloses a measuring device and a measuring method for argon tungsten-arc welding arc force, and belongs to the technical field of arcs. The measuring device comprises a balance plate, a balancing weight, a support plate, an asbestos heat insulating piece, fixing bolts, a cross-shaped laser, a spring, a limiting rod, a fixing clamp, a level bubble, bearing seats, deep groove ball bearings, linear bearings, a bearing rod, a support frame and a scaleplate. The measuring device is mainly used for measuring the arc force of argon tungsten-arc welding and the measuring method based on the argon tungsten-arc welding, and can achieve the measurement of welding arc force of common metal materials. The measuring principle is based on the lever law and the Hooke law, the measuring process is simple and easy to do, and the measuring error small. According to the measuring device and the measuring method for the argon tungsten-arc welding arc force, the arc force generated by the metal materials and the arcs under the interaction can be truly reflected; the limitation that a water-cooled copper plate with small holes is used as a measuring block is improved, and the measuring result is more real; meanwhile, the interference of an electromagnetic field is avoided when a sensor is used for measuring.
