Abstract
The invention discloses technology for rod melting connection for an aluminum-based composite material, in particular an upsetting plasma arc welding process method for the aluminum-based composite material. High-energy density beams with concentrated arc energy and high straightness and arc penetration serve as a welding heat source, so that the whole connecting time is shortened, the heated area is reduced, heat input is reduced to the greatest degree, and the problem of deterioration of welding seam structures is effectively improved; moreover, after a joint of the aluminum-based composite material is molten, the molten weld metals are extruded by utilizing a pretightening force through a special fixture, the burnt enhanced phase is extruded, the joint is purified, grains of the welding joint are close to base metals and a new phase is not produced, the welding line of a welded joint is saturated, a joint basically consisting of uniform base metals is obtained, and the tensile strength of the welded material is guaranteed to the greatest degree.
Description
technical field [0001] The invention relates to an aluminum-based composite material fusion welding technology, in particular to an aluminum-based composite material upsetting plasma arc welding fixture and an arc welding method. Background technique [0002] Due to its advantages of high comprehensive performance, low manufacturing cost, isotropy, and good secondary processing performance, particle-reinforced aluminum matrix composites have broad application prospects in aviation, aerospace, automotive and other industrial fields. Due to the introduction of reinforcements in aluminum matrix composites, the welding process has become quite difficult, mainly due to the physical and chemical properties between the reinforcement and the base aluminum alloy, such as melting point, electrical conductivity, thermal conductivity and linear expansion coefficient, etc. There are huge differences, which lead to defects such as porosity, inclusions, component analysis and poor weld for...
