Abstract
The invention discloses a resistance welding method. When aluminum is spot-welded on a spot welding machine, the aluminum to be spot-welded is placed on a spot welding platform and is covered by a thin aluminum foil, the thin aluminum foil is covered by a thin copper foil, and welding parameters are adjusted to control a spot welding head to perform resistance spot welding. When a thin aluminum electrode is welded, the spot welding head is separated from the electrode by a thin copper sheet, and the part in contact with the spot welding head is the copper foil during welding, so that the welding head of the spot welding machine does not stick the thin aluminum electrode when the copper foil is used as a sacrificial layer. Therefore, after the copper foil is used as the sacrificial layer, the spot welding head does not stick the aluminum foil, so that the service life of the spot welding head is prolonged and the production efficiency is improved.
Description
?
Technical field
The present invention relates to a kind of method for resistance welding.
Background technology
Electric resistance welding is to make metallic bone, docking site flow through electric current, utilizes the heating of the contact resistance and the intrinsic resistance of metal, makes the contact site reach the melt temperature of metal, and in a suitable manner method to the Pressure Welding of weld part pressurization.In process of production during the aluminium electrode of CD spot welding thin material matter, because the aluminum foil thickness of welding is little, when contact point is in molten condition, very easily with the aluminium foil burn-through, after the general spot welding 10 ~ 15 times, the sticking easily aluminium electrode of some soldering tip, and aluminium foil is by burn-through, thereby can not reach the effect of welding.In order to make the not sticking electrode of a soldering tip, must often clean out a soldering tip, welding efficiency is low.
Summary of the invention
The problems referred to above that the present invention is run into when solving resistance welded, having proposed a kind of resistance spot welding time point soldering tip can not glue aluminium foil, and aluminium foil is by burn-through, can effectively improve the method for resistance welding of the efficient of service life of a soldering tip and production.
Method for resistance welding of the present invention, it is when carrying out aluminium spot welding on mash welder, to be placed on the spot welding platform by the spot welding aluminium, is coated with a thin aluminium foil on by the spot welding aluminium, adjust welding parameter control point soldering tip and carry out resistance spot welding, on described thin aluminium foil, also be coated with a thin copper foil sheet.
The thickness of described thin copper foil sheet is 0.1 ~ 0.5mm.
When welding thin material matter aluminium electrode, every a slice scale copper, the position of welding time point soldering tip contact is a copper foil between a soldering tip and electrode, and the soldering tip of mash welder just can not cling thin aluminium electrode when welding as sacrifice layer with Copper Foil like this.Therefore, after the present invention had adopted and used Copper Foil as sacrifice layer, the some soldering tip just can not glue aluminium foil, had improved the service life of some soldering tip and the efficient of production.
Description of drawings
Accompanying drawing is a Principle of Process schematic diagram of the present invention.
The specific embodiment
Method for resistance welding of the present invention can be used for the resistance welded of batteries of electric automobile aluminium electrode, before employing medium frequency inverter mash welder welds
,Regulate parameter before the welding earlier, squeeze time is set to 650ms, and a time is 2s, and electric current is 25% of an integral body, pulse number is 1, to be installed on the CD spot welding platform 4 by spot welding aluminium aluminium electrode, will approach aluminium foil 5 then and be placed on the aluminium electrode 3, on thin aluminium foil, place the thick thin copper foil sheet 2 in the 0.2mm left and right sides again, step on control pedal, thin aluminium foil of CD point soldering tip 1 welding and aluminium electrode are taken the thin copper foil sheet on the aluminium foil off after spot welding finishes, welding is promptly finished.Because when welding thin material matter aluminium electrode, every a slice scale copper, the position of welding time point soldering tip contact is a copper foil between a soldering tip and electrode, the soldering tip of mash welder just can not cling thin aluminium electrode when welding as sacrifice layer with Copper Foil like this.Therefore, the present invention adopted with Copper Foil as sacrifice layer after, the some soldering tip just can not glue aluminium foil, has improved the service life of some soldering tip and the efficient of production.
