Technical Field

[0001] This utility model relates to the field of welding device technology, specifically a new type of movable welding device. Background Technology

[0002] In many industrial fields such as machinery manufacturing, shipbuilding, steel structure engineering, and pressure vessel production, the welding of splicing seams between steel plates is a core process to ensure the strength, sealing, and overall performance of structural components. The welding quality directly determines the safety, reliability, and service life of the final product. With the continuous expansion of industrial production scale and the continuous improvement of product precision requirements, the efficiency and quality control of steel plate splicing welding operations are facing increasingly severe challenges.

[0003] However, traditional welding operations for splicing seams between steel plates involve operators holding welding machines on-site. During the welding process, operators must continuously hold the welding torch and maintain a stable posture, while also facing the intense light, high temperature, and fumes generated by the welding arc at close range. Prolonged exposure to such harsh working environments can easily lead to occupational health problems such as eye fatigue, skin burns, and respiratory damage. To address these issues, the inventors have proposed a novel, portable welding device to solve these problems. Utility Model Content
