Problems solved by technology
Electromagnetic heating and crawler heating can heat evenly, but it takes a long time to lay and recycle the heating belt, and the heating takes a certain time, which affects the production efficiency; manual heating can be synchronized with welding, and welding is performed while heating, but manual flame heating needs Dedicated personnel to operate, double the number of construction workers, greatly increasing the construction cost, at the same time, manual operation is unevenly heated, which affects the welding quality
Therefore, the above-mentioned heating method has high limitations in heating, and it is especially not suitable for preheating construction operations of large quantities of fillet welds.

The invention discloses a welding heating device, which includes a drying gun and a positioning frame for the drying gun. The drying gun includes a connecting rod, a drying nozzle, a first connecting pipe and a second connecting pipe. The inside of the connecting rod is hollow, and the drying nozzle is arranged on the connecting rod. One end of the first connecting pipe is connected with the connecting rod, and the other end is externally connected with an oxygen pipeline for transporting oxygen; one end of the second connecting pipe is connected with the connecting rod, and the other end is externally connected with a high-energy gas pipeline for transporting high-energy gas , Oxygen and high-energy gas are mixed inside the connecting rod and then ignited through the drying nozzle, and the flame outlet of the drying nozzle is facing the weldment; on the frame, and the connecting rod is located in front of the welding trolley. The welding seam heating device in the present invention is installed on the welding trolley, and moves synchronously with the welding trolley, performs welding heating synchronously while performing welding operations, and realizes automatic welding seam heating and welding consistency.
Description
technical field [0001] The invention belongs to the technical field of shipbuilding equipment, and in particular relates to a welding heating device which cooperates with the welding operation of an automatic welding trolley to realize automatic heating of welding seams. Background technique [0002] During the shipbuilding process of shipbuilding enterprises at home and abroad, when welding thick plates, the carbon equivalent of welded parts is too high or the ambient temperature is too low, hardened structures are easily formed at the joints, which reduces the mechanical properties of the joints and even produces welding cracks. Thus affecting the welding quality. [0003] In order to ensure the welding quality, for the welded parts in the above cases, preheating should be carried out before welding, and the area to be welded and the surrounding area should be heated to a certain temperature to achieve the following four purposes: ① It can prolong the solidification time o...
