Abstract
Solder flux T shape weldering welding and solder flux, its welding be between the solder side of two welded parts every being equipped with welding flux layer, can obtain bigger resistance heat not enlarging the mash welder capacity and not increasing under the condition of electric current, can reduce by 20 percent electric energy, and can improve the quality of welding; Its solder flux can adopt epoxyn, conducting resinl, magnetic-conductive adhesive etc., and solder flux of the present invention is by epoxy resin, diluent, curing agent, metal powder mixed preparing; Solder flux has the thermal fusible of being subjected to and easily forms weldering nuclear, and can promote the formation of welded part solder side weldering nuclear and expand layer.
Description
The invention belongs to the welding technology field class.
T shape welding is a kind of in the welding procedure, is similar to upset butt welding; It is by big electric current, in seam place of two workpiece heat that has a resistance to two soldered workpiece.Make the metal molten of seam place, two welded parts are fused into one.The weldering of traditional T shape is that two welded parts are directly contacted welding, and because of welded part is a metal, conductance is big, resistance is less, and under the certain condition of electric current, the workpiece that resistance is more little, the resistance heat that is produced are more little; So traditional T shape welding often occurs because of the not enough phenomenon that causes welded part not weld penetration, dry joint of resistance heat.Want to guarantee welding quality, do not produce above-mentioned phenomenon, then must increase the capacity of mash welder, increase electric current; Will waste bigger electric energy like this.
The objective of the invention is: provide a kind of and can save solder flux T shape weldering welding electric energy, that welding quality is good, and utilize the employed solder flux of this welding.
Technical measures of the present invention are:
1. adopt solder flux T shape weldering welding, just adopt between two welded parts, strengthens the resistance between two welded parts, the quality of raising resistance heat and welding every the T shape welding method that is equipped with welding flux layer.
2. in T shape welding procedure, use solder flux; Employed solder flux has: conductance is little, resistance is big, be subjected to thermal fusible formation weldering nuclear, can promote formation and expansion that the weldering of welded part solder side is examined; Improve the quality of welding and the consumption of saving electric energy.
According to Jiao Er-stupefied thatch law, the resistance heat Q value of electric resistance welding should be:
Q＝0.24∫
t oI
2（t）R
0（t）dt
R wherein
0=R
1+ R
2+ R
3;
R
1The internal resistance of-welded part;
R
2Contact resistance between-welded part and the electrode;
R
3Contact resistance between the-welded part.
From following formula as can be seen, to the workpiece with a kind of material, R
1, R
2Resistance constant.Under the constant situation of electric current, if increase R
3During resistance, can increase resistance heat Q value, the present invention will not enlarge the welding machine capacity, not increase under the condition of electric current, by increasing R
3Resistance obtains bigger resistance heat, improves the welding quality of T shape weldering, reduces the consumption of electric energy.Its concrete method is, at welded part seam face place every put resistance big, that be subjected to thermal fusible formation weldering nuclear, can promote two welded parts weldering karyomorphisms to become and the solder flux of expansion.In welding process, solder flux at high temperature is melted, burning and carbonization, does not play bonding effect, and this also is different from the spot welding technique for sticking.
The present invention uses solder flux in T shape welding procedure, this solder flux can be: existing epoxyn, neoprene-phenol adhesive, conducting resinl, magnetic-conductive adhesive, spot welding glue etc.The solder flux that also useful epoxy resin 100 grams of solder flux of the present invention, diluent 8-15 gram, curing agent 40 to 60 grams, metal powder 10 to 20 grams mix together; Wherein epoxy resin adopts E-44 epoxy resin, diluent to adopt DBp dibutyl phthalate, curing agent to adopt 651
It is preferred plan that Versamid, metal powder adopt the solder flux of 200 order to 300 purpose copper powders or iron powder mixed preparing; Because this solder flux is toxic little, the advantage that cost is low.
Solder flux T shape weldering welding of the present invention is every the welding method that is equipped with welding flux layer between the solder side of two soldered workpiece; Solder flux can stick on the solder side of one of them welded part; Solder flux also can stick to two simultaneously by on the solder side of fitting, for the workpiece of producing in batches, after on the solder flux elder generation solder side that sticks to a welded part in batches, carry out drying processing (natural air drying or oven dry), and then it is more convenient to carry out soldered near T shape welding.
