Embodiment Construction

[0033] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific diagrams.

[0034] refer to figure 1 , figure 2 , image 3 , Figure 4 , infrared preheating friction welding process,

[0035] Step 1, take at least two weldments;

[0036] Step 2, heating the welding part of at least one weldment, that is, the contact end surface of the weldment, through a heating plate 7 as a heat source;

[0037] Step 3, welding at least two weldments by a friction welding process.

[0038] This process organically combines the heat generated by the heat source and the heat generated by friction, which can make the contact end surface of the weldment quickly reach a molten state, and solve the problems of impurities, cold slag, flash, slow welding speed, and forming The problem of poor performance. At the same time, the heat generate...

Abstract

The invention relates to the welding technology, particularly to an infrared preheating friction welding process. The infrared preheating friction welding process comprises the steps of, firstly, obtaining at least two workpieces to be welded; secondly heating the welding position, namely, the contact end surface of at least one workpiece to be welded through a heating plate serving as a heating source; thirdly, welding the two workpieces to be welded through a friction welding process. An infrared preheating friction welding tool comprises a frame which is provided with a friction welding device, and the heating plate which is used for heating the contact end surfaces of the workpieces to be welded, wherein the heating plate is provided with heating wires according to the contour of the contact end surfaces of the workpieces to be welded and is movably connected with the frame. The heating wires can heat the workpieces to be welded, so that heat generated by the heating wires can be organically combined with heat generated due to friction, and the contact end surfaces of the workpieces to be welded rapidly reach or approach a molten state, and further the problems existing in a welding mode which only relies on the heat generated due to friction, including impurities, cool slag, flashes, low welding speed and poor forming effects, can be solved.

Description

technical field [0001] The invention relates to welding technology, in particular to friction welding. Background technique [0002] Friction welding is a process in which the friction welding tool frictionally heats the weldment at a fixed frequency and amplitude through electric, pneumatic or hydraulic transmission, so that the contact end surface of the weldment reaches a molten state, thereby realizing the welding process. It has the advantages of good quality, short construction period, low noise and less pollution. However, the traditional friction welding process has high energy consumption and slow welding speed, and there are often impurities, cold slag, flash, etc. in the welding place. Contents of the invention [0003] The object of the present invention is to provide an infrared preheating friction welding process to solve the above technical problems. [0004] The purpose of the present invention is also to provide a welding tool for infrared preheating fri...
