Description

technical field [0001] The invention relates to the field of welding devices, in particular to an intelligent heating and welding device and method. Background technique [0002] The butt joint between the insulation pipe sections needs to be operated on site, the welding joint between the insulation pipe sections needs to be filled with PE pipe, and the gap between the pipe sections needs to be insulated and welded. The hot-melt sleeve is welded and hot-melted, and polyurethane insulation material is injected inside. A layer of heating resistance wire mesh is attached to the inner wall at both ends of the hot-melt sleeve. External power supply at both ends for heating and welding, heating for a period of time, visually observe whether the material softens to reach the melting point, remove the power supply when reaching the melting point, and let it cool down, so that the outsourced welding material and the base material are combined into one, reaching the joint of the pipe...

[0002] The butt joint between the insulation pipe sections needs to be operated on site, the welding joint between the insulation pipe sections needs to be filled with PE pipe, and the gap between the pipe sections needs to be insulated and welded. The hot-melt sleeve is welded and hot-melted, and polyurethane insulation material is injected inside. A layer of heating resistance wire mesh is attached to the inner wall at both ends of the hot-melt sleeve. External power supply at both ends for heating and welding, heating for a period of time, visually observe whether the material softens to reach the melting point, remove the power supply when reaching the melting point, and let it cool down, so that the outsourced welding material and the base material are combined into one, reaching the joint of the pipe section Welding with the parent pipe to achieve the purpose of heat preservation, this process is dependent on human operating experience, there is a large difference in temperature during the welding process, and it is difficult to guarantee the pressure used when fixing, so the quality of welding cannot be guaranteed and unified. The process cannot be monitored, and the strength cannot be guaranteed. Insufficient welding often occurs, and the sealing requirements cannot be met, or the transition of welding damages the insulation pipe, which makes the quality of the welding joint of the insulation pipe section a potential safety hazard and increases the damage of the insulation pipe section. chance, thereby increasing the cost of later repairs
