[0002] A blast furnace is a device used to produce iron, usually constructed of refractory materials, and is used to heat raw materials such as iron ore, coke and limestone to high temperatures to reduce the iron oxide in the iron ore to iron. Since slag and other impurities will accumulate in the furnace during the operation of the blast furnace, these accumulations may affect the normal operation of the blast furnace, so the blast furnace needs to be cleaned and maintained regularly. Blast furnace drill rods are usually used for cleaning and maintenance of the blast furnace. The blast furnace drill rods can be used to clean out these deposits and slag to keep the inside of the blast furnace clean. The drill rods can also be used to check whether the refractory materials inside the blast furnace are severely worn, and whether there are other equipment failures, and repair and replace them in time. After long-term use, the blast furnace drill rod may break or the drill rod head may break and fall off, and the blast furnace drill rod needs to be welded and repaired. In the prior art, ordinary welding machines are usually used for welding and repairing blast furnace drill rods. However, in order to adapt to the groove of the drill rod, the angle of the welding gun needs to be manually adjusted, resulting in high labor intensity for the staff and low welding efficiency of the drill rod.
