Abstract
The resistive spot welding process has connecting parts added between the welded parts of steel, including stainless steel. The present invention has the advantages of the contact between the connecting part and the welded parts resulting in concentrated welding current, fast heating, small electrode force and less pressure impression; the combination of the fast molten connecting part with the welded parts resulting in less heat area influence, high strength and large welding kernel; capacity of welding high electric conductivity and high heat conductivity material as well as non-metal material to steel including stainless steel; and higher connecting strength and higher surface quality compared with riveting and adhering.
Description
Technical field:
The present invention relates to a kind of welding procedure, especially relate to a kind of resistance spot welding process that has connector.
Background technology:
Resistance spot welding is the resistance heat (mainly being the heat that the contact resistance between the workpiece produces) by workpiece itself, realizes to steel, stainless steel and aluminium being the welding of the metal sheet of material, is widely used in manufacturing industry such as automobile, aviation.Traditional resistance spot welding need not added any additional materials, in order to make between workpiece contact preferably, adds bigger pressure between electrode, so there is impression in workpiece after having welded, and influences the specious of workpiece; The heat affected area is arranged, the easy embrittlement of the metal of heat affected area; And the size of weldering nuclear is relevant with the thickness of workpiece, and when workpiece was thin, weldering nuclear was less, and bonding strength is low.
In addition, at present along with the special requirement of some machine constructions,, use the sandwich construction of steel or stainless steel and nonmetallic materials (as the highstrenghtpiston) as heat insulation, noise reduction etc.Because traditional spot-welding technology can not weld insulating materials and steel or stainless steel, and several methods of attachment below normal the employing: (1), riveted joint or bolt connect, and the two sides of this method workpiece all exists manufactured head or bolt head, the surface of the work out-of-flatness, not attractive in appearance, influence is used; And operation is many, and production efficiency is low.(2), adhering method, the joint of this method can only use at low temperatures, and intensity difference, to the cleaning of surface of the work require high, cost is high.
Summary of the invention:
The object of the present invention is to provide a kind of bonding strength height, a kind of resistance spot welding process that surface quality is good.
Purpose of the present invention is by following technology art scheme implementation: its process conditions are as follows: increase connector between weldment.
The material of described weldment is a steel or stainless steel, connector to be shaped as thin slice circular, the outer ring diameter of described thin slice annulus connector is 0.7-0.9 a times of electrode diameter, and interior ring diameter is 0.2-0.4 a times of electrode diameter, and thickness is 0.5-1 times of workpiece minimum thickness.
The material of described weldment is the high conductive material plate, or thermoconductive material board, or dielectric panel and steel plate or corrosion resistant plate weld, connector be shaped as cone-shaped nail, the end face diameter of cone-shaped nail connector is 0.7-0.9 a times of electrode diameter, height is 1.1-1.3 a times of welding work pieces gross thickness, and drift angle is 30-35.
The material of described connector is a steel or stainless steel.
Described insulating materials is nonmetallic materials.
Advantage of the present invention is: the material of weldment is a steel or stainless steel, because the contact area of connector and weldment is little, contact is good and electric current is concentrated, and heat production speed is fast, so available less electrode force, and electrode is little at the impression of workpiece; Since connector fast fusing and weldment seam up and down together, the heat affected area is little, intensity is high, and the diameter of weldering nuclear is almost irrelevant with the thickness of workpiece, also can obtain bigger weldering nuclear when workpiece is thin.The material of weldment is a high conductive material, or Heat Conduction Material, or insulating materials and steel or stainless steel weld by connector, overcome that the traditional resistor spot-welding technology can not conduct electricity to height, Heat Conduction Material (as copper coin) and steel plate or corrosion resistant plate, and the shortcoming that is connected with steel plate or corrosion resistant plate of non-metallic plates.And compare with splicing with riveted joint, have bonding strength height, advantage that surface quality is good.
