Description
Technical field
The present invention relates to technical fields of mechanical processing, are specifically a kind of metal plate welding method.
Background technology
At present, in metal plate manufacturing industry, welding is used as a kind of common connection method, is widely used, adopts now
The method welded with current point, the metal plate plate of two same materials is placed between two welding electrodes and is welded.Spot welding
The tip area of welding electrode is smaller, generally approximates the size of desired solder joint, logical after the welding electrode of both sides is powered
Sufficiently large electric current is crossed, substantial amounts of resistance heat is generated in the contact position of welding electrode and plate, so as to two plate alignment welderings
Molten bath is generated centered on the region of receiving electrode, until power-off cooling when molten bath meets spot size, molten bath zone formation before one
The solder joint of area is determined so that two workpiece fuse together.But existing bonding machine and welding procedure be after welding, due to
Electrode needs workpiece pressing and two plates are except welding position is also bonded to each other with outer portion, it is therefore desirable to larger electric current,
And dent can be left in the positive and negative of workpiece, moreover, since plate is relatively thin, when molten bath, size meets, plate
The bad control of fusion penetration of thickness direction or even there is the phenomenon that burn through, solder joint appearance is difficult to be guaranteed after cooling, for appearance
Quality considers, for positive dent is overcome using the benefit soil in rear road, therefore processing cost is caused to increase.

For the mix powder of granularity 150-250 mesh, mix powder is made of following components：10-20 parts of sodium fluoride, chrome green
For 5-10 parts, 3-5 parts of di-iron trioxide, 3-5 parts of titanium dioxide, 1-3 parts of manganese oxide, 2-4 parts of ammonium chloride, 5-10 parts of zinc chloride,
2-4 parts of silica, in terms of parts by weight, solubilizer is tuned into paste during use；
(3) the end set boss for being soldered sheet metal component described first；Sheet metal component and second is soldered by first to be welded
It connects sheet metal component and placement is docked according to design requirement；
(4) will guide into long and narrow pipeline to form admixture of gas containing argon, helium, carbon dioxide and their mixture；
Carry out the flowing of correcting gas mixture using flowing adjuster, to form ternary gas mixture as welding protection gas；
(5) it is soldered sheet metal component by first and carries out the pre-heat treatment, 400-420 DEG C of preheating temperature, by welding rod to be welded
It is heated to 200-220 DEG C；It is welded in the contact position of the boss and the second soldered sheet metal component；
(6) after welding, welded part is placed in 180-220 DEG C of baking oven or incubator and is slowly cooled to room temperature, it is cold
But to room temperature welded part cleaned with 50-70 DEG C of warm water after naturally dry.
As further embodiment of the present invention：The boss is cone.
As further scheme of the invention：The ratio model that the height of the boss is soldered sheet metal part thickness with first
It encloses for 0.2-0.6；The conical base diameter of the boss and the first ratio range for being soldered sheet metal part thickness are 0.8-1.2；
