Abstract

The invention discloses a welding gun system suitable for medium thick plate welding. The welding gun system comprises welding gun assemblies and a welding gun fixture, wherein the welding gun assemblies comprise a plurality of welding guns and are configured to conduct multi-layer single track welding on a medium thick plate structure piece at the same time when the welding gun fixture is adjusted to a certain space position; and the welding gun fixture is configured to be a fixture structure which can drive the welding gun assemblies to adjust the space position during welding, the welding gun fixture is provided with a fixture base and a plurality of welding gun space position adjusting assemblies formed on the fixture base, and the multiple welding gun space position adjusting assemblies can drive the welding gun assemblies fixedly connected to the welding gun space position adjusting assemblies correspondingly to adjust the space positions during welding. According to the weldinggun system, by adopting the multiple welding guns to conduct welding at the same time, many defects of traditional welding methods for medium thick plate structure pieces are overcome; and meanwhile,the welding gun system has the characteristics of being low in cost, beautiful in formed welded seams and high in welding performance, and is high in welding speed and large in welding cladding amount, and the welding efficiency of the medium thick plate workpiece is greatly improved.

Description

technical field

[0001] The invention relates to the field of welding technology, in particular to a welding torch system and a welding method suitable for welding medium and thick plates. Background technique

[0002] For a long time, medium and thick plate structural parts have been widely used in large-scale projects, such as shipbuilding, container manufacturing, mining machinery, construction engineering, bridge manufacturing and other fields, which has caused a substantial increase in welding workload, coupled with welding production labor The increase in cost has put forward higher and higher requirements for welding production efficiency. The development of high-efficiency welding equipment and technology has become one of the focuses that the manufacturing industry pays close attention to.

[0003] At present, traditional manual arc welding, submerged arc welding, electroslag welding or FCB welding are generally used for welding structural parts of medium and thick p...
