2results about How to "Stable welding arc" patented technology

The application belongs to the technical field of welding robots, and discloses a multi-machine cooperative intelligent mobile welding robot for ship manufacturing based on flexible manufacturing, which comprises a mobile base, the top of the mobile base is provided with a welding mechanical arm, and further comprises a height adjusting part arranged at the bottom of the welding mechanical arm and used for adjusting the height of the welding mechanical arm; the height adjusting part comprises a fixing box which is fixedly connected to the inside of the mobile base. Through the three-layer nested structure of the fixing box, the intermediate box and the jacking box, and the transmission design of the speed reducer, the screw rod and the screw cylinder, the welding mechanical arm can be precisely adjusted in height, the welding demand of different height positions in ship manufacturing can be met, the welding efficiency is improved, the welding gun can be aligned with the weld at a suitable angle, the welding arc is stable, the weld is well formed, and welding defects are reduced.

A Fe-Mn series damping steel gas shielded flux-cored wire, comprising a stainless steel sheath and a flux core, the weight of the flux core accounting for 13-15% of the total weight of the flux-cored wire, the raw material composition of the flux core and the weight percentage content thereof being as follows: 2-3% of marble, 50-55% of rutile, 3-4% of feldspar, 45 # 6-8% of ferrosilicon, 2-3% of rare earth fluoride, 5-7% of magnesium powder, 3-4% of electrolytic manganese, 2-3% of sodium fluoride, and the balance being iron powder. The present application not only has good all-position welding process performance and beautiful weld, but also has excellent mechanical properties and reaches ultra-low hydrogen level of diffusible hydrogen content of deposited metal, and can meet the welding requirements of Fe-Mn series damping steel.
