Problems solved by technology
[0004] The gas shielded welding of the above-mentioned steel bars adopts manual or semi-automatic welding methods, which not only have problems such as uneven welding, low welding quality, high labor intensity and low welding efficiency, but also can only be judged by people whether to weld a full circle or not. Time cannot be automatically controlled
Although submerged arc welding adopts an automatic welding method, some operations still need to be performed manually, and are not combined with the control of gas shielded welding

Description
technical field [0001] The invention relates to the field of welding technology, in particular to an automatic control system applicable to gas shielded welding and submerged arc welding of steel bars. Background technique [0002] Gas shielded welding is an arc welding that uses gas as the arc medium and protects the arc and the welding area. It has the characteristics of no slag, high welding efficiency, small deformation of the weldment after welding, and is conducive to the automation of the welding process. In machinery factories, 45 steel bars with different diameters are often connected by gas shielded welding first, and then turned. When welding, it is necessary to weld a circle at the joint of the steel bar material, and the welding is required to be uniform. The method of welding the welding torch around the joint of the steel bar material without moving the steel bar material can also be adopted. The way that the steel bar rotates at a constant speed while moving...
