Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to an improved gantry welding machine. Background Art

[0002] A welding machine is an electrical appliance that provides a power source with certain characteristics for welding. Welding is flexible, simple, convenient, strong and reliable, and the strength of the welded material is even the same as that of the parent material. It is widely used in various industrial fields, such as aerospace, shipbuilding, automobiles, containers, etc. The gantry welding machine adds the displacement and displacement functions to the welding machine, so that welding can be performed at different positions of the weldment, which improves efficiency and saves a lot of manpower.

[0003] For example, a gantry welding machine with the authorization announcement number CN215588272U includes a base, a gantry is slidably provided on the base, a plurality of welding gun assemblies are slidably provided on the gantry, and the welding gun assemblies include a position adjustment unit, a first welding gun and a second welding gun. Although the above-mentioned document can adapt to ladders or partitions of different sizes without manual adjustment, which greatly improves production efficiency, when the gantry welding machine is in use, when welding the workpiece, a short circuit occurs when the welding machine contacts the welding object and the welded object, and the short circuit generates a high-temperature arc, which melts the welding object, which will produce welding slag and arc light. The generated welding slag is easy to splash around and splash onto the staff, causing burns. In addition, the arc light generated during welding will cause damage to the eyes of the staff, thereby reducing the safety of the gantry welding. Utility Model Content
