Multi-layer sharp angle magnetic control welding generating device and welding gun

Abstract

The invention provides a multi-layer sharp angle magnetic control welding generating device and a welding gun, and relates to the technical field of welding. The multi-layer sharp angle magnetic control welding generating device comprises at least four magnet groups and a mounting assembly, the mounting assembly is mounted on the head of the welding gun, the magnet groups are mounted on the mounting assembly, and all the magnet groups are arranged in the axial direction of the welding gun head; and each magnet group includes an even number of magnetic poles, each magnetic pole includes an evennumber of N poles and an even number of S poles, the magnetic poles in each magnet group are arranged in the circumferential direction of welding arc in an array mode, and the homopolar magnetic poles are arranged opposite to each other. Through the arrangement of the magnetic poles, a sharp angle magnetic field is formed, under the action of the magnetic field force, the welding arc is compressed, the cross-sectional area of the arc acting on a weldment is reduced, the stiffness of the arc is increased, the expansion of the arc during argon tungsten-arc welding is avoided, the penetration depth during welding is also deeper than the conventional penetration depth, and the magnetic control welding generating device is compact and convenient and is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a multi-layer sharp-angle magnetron welding generating device and a welding torch. Background technique [0002] The advantage of argon tungsten arc welding is to achieve high-quality welding and excellent weld seam, easy to maintain constant arc length, constant welding current, stable welding process, so that the weld seam is beautiful, smooth and uniform, especially suitable for thin plate welding ; Almost all metals and alloys can be used for connection. Therefore, it has a wide range of applications and great value in various fields, especially in the pressure vessel, aerospace and welded pipe industries. However, the current-carrying capacity of argon tungsten arc welding is limited, and the arc is easy to expand and not concentrated, which limits the power density of welding, resulting in small penetration, low deposition speed, low welding speed, and thus low productivi...
