Abstract
A method for welding the internal container of a dual-layer insulating canteen made of stainless steel includes such steps as degrasing the position to be welded, putting the workpiece in a rotary profile mould, fixing, inserting an argon-arc welding torch in the workpiece, fixing, driving the profile mould to rotate, starting electric arc, and welding by more than a turn.
Description
Technical field
The present invention relates to metal welding techniques, particularly double-layer stainless steel is incubated tubular article, such as the welding of thin-wall stainless steel inner bags such as heat preservation coffee pot, thermos cup, vacuum flask.
Background technology
Mostly the welding of traditional stainless steel thin-wall class tubular article such as the inner bag of double-layer vacuum stainless steel thermo jug, is to be welded by two parts at the bottom of the courage tube of stretch forming and the courage.Two parts have makes 90 ° of seams welding, also has to make 180 ° of welding, no matter is 90 ° of welding or 180 ° are welded, and welding gun 5 all welds outside tube, and as shown in Figure 1 and Figure 2, if make 90 ° of welding easily, but difficulty is cleaned at 90 ° of dead angles in the tube; Make 180 ° of welding, cleaning is easy but welding is very difficult, and high-grade goods all require 180 ° of welding at present.As everyone knows, welding can produce high temperature, and high temperature can allow the bad stainless steel work-piece bulging deformation that conducts heat, and a tube inwall seam crossing can produce the uneven phenomenon, makes the welding procedure difficulty that becomes, and the workpiece fraction defective is higher.
Summary of the invention
The object of the present invention is to provide the good stainless steel kettle of a kind of welding in the tube, welding quality, the welding method of tube.
The welding method of inner bag of heat preservation pot of bilaminar stainless steel of the present invention is characterized in that being undertaken by following operation:
The ungrease treatment of stainless steel interface;
Welded piece is put into the rotating pattern of being made by copper material or aluminium, make the welded piece outer wall of butt joint and pattern inwall closely connected, fixing;
Rotate at the bottom of making pattern drive courage tube and courage, the electric arc that ignites, welded piece rotate stall when being slightly larger than a circle, receive arc;
Welder's part takes out from pattern.
Described welded piece is meant at the bottom of courage tube and the courage.
Described pattern is being shaped on the scrobicular ring that width is slightly larger than seam with joint at the bottom of courage tube and the courage, enters the back for argon gas from seam; Pattern is made by copper material or aluminium.
Under the less situation of the port bore that supplies welding gun to stretch into of courage tube, rob head at welding gun one sight glass and little shot-light are set, observe welded condition by peeping pipe.
The present invention is owing to weld in kettle, tube, because the outer wall of workpiece is entangled by the good pattern of heat conduction, the heat energy that swells that is heated of workpiece is absorbed rapidly by pattern, avoided the uneven phenomenon of seam crossing, simple for process, can guarantee weld seam and welding quality again, cost is low, work efficiency is high, has significant superiority.

The specific embodiment
Describe soldering stainless steel thermo jug inner bag embodiment of the present invention in detail below in conjunction with accompanying drawing.
When soldering stainless steel kettle inner bag, undertaken by following operation:
2 interfaces acetone ungrease treatment at the bottom of stainless steel courage tube 4 and the courage;
With at the bottom of courage tube 4 and the courage 2 put into rotating, by the pattern 1 that copper material or aluminium are made, make at the bottom of the courage tube of butt joint and the courage outer wall and pattern inwall closely connected fixing.Because the affinity of stainless steel and oxygen is very big, if do not take argon-filled protection, fusion welding metal oxidation in welding process easily produces weld defect.Argon tungsten-arc welding is a kind of high-quality precision welding connection technology, is the desirable welding method of welding thin-walled class stainless steel.So when carrying out stainless steel kettle, tube argon arc welding, adopt argon tungsten-arc welding usually.For can guarantee weld seam just, back side welding quality, the inwall of pattern 1 is being shaped on the scrobicular ring 13 that width is slightly larger than seam with joint at the bottom of courage tube and the courage, enters the formed argon gas of back scrobicular ring chamber from seam 3 for argon gas; The welding gun 5 of the argon arc welding non-butt end oral area from courage tube 4 is stretched into, make torch head aim at seam 3, then fixing welding gun; As shown in Figure 4, the argon gas in the argon bottle 8 is connected to argon-arc welding gun 5 by decompression flowmeter 7; Two output stages of tungsten argon arc welding machine 6 connect welding gun 5 and pattern 1 respectively; Rotate at the bottom of making motor-driven pattern 1 drive courage tube and courage, the electric arc that ignites, pattern rotate stall when being slightly larger than a circle, receive arc; The inner bag that constitutes at the bottom of the courage tube that welded and the courage taken out from pattern get final product.
Port footpath for welded piece is less, is difficult to observe the welding situation, can rob 5 setting-sight glass 9 and a little shot-light 11 at welding gun, observes by peeping pipe 10, as shown in Figure 3.
In view of thermos cup, vacuum flask all belong to double-layer stainless steel insulation tubular article, be equal to the stainless steel thermo jug, so the heat preservation pot of bilaminar stainless steel, cup, the bottle that utilize the present invention to produce all should belong within the application's the scope of patent protection.
