Abstract
The invention provides a welding gasket for stainless steel CO2 single-sided welding. The welding gasket is formed by connecting a plurality of welding gasket blocks end to end, wherein the bottom surfaces of the welding gasket blocks are adhered to aluminum foil adhesive tapes; each welding gasket block is prepared from the following raw materials in percentage by weight: 25 to 35 percent of china clay, 15 to 25 percent of alumina, 18 to 25 percent of talc, 13 to 18 percent of quartz, 15 to 20 percent of feldspar, 2 to 5 percent of titanium dioxide and 5 to 8 percent of calcium carbonate; and the sum of the weight of the components is 100 percent. Slag of the gasket is adapted to a slag system of a stainless steel welding material and the melting point of the slag is suitable for the melting point of the stainless steel. The properties such as surface tension, flowability and consistence of liquid slag generated in the using process are suitable for the welding metallurgy process of the stainless steel, so that tidiness and smoothness of back and appearance of weld joint are guaranteed, high quality of the weld joint of single-sided welding is guaranteed, the welding materials are saved and the welding production efficiency is improved.

Specific embodiment
Embodiment 1
Referring to the drawings 1,2,3,4.The present invention is rustless steel co2The welding backing of single welding complete sets of Techniques, described welding lining
Pad 11 is joined end to end by some block welding spacer block 1 and forms, and the bottom surface of described welding backing block 1 is mounted on aluminum foil and adhesive tape 2, institute
The formula material weight proportion stating welding backing block 1 is as follows:
Potter's clay 25 ~ 35%, Alumina 15 ~ 25%, Talcum 18 ~ 25%, quartz 13 ~ 18%, Anhydrite 15 ~ 20%, titanium dioxide 2 ~ 5%, carbon
Sour calcium 5 ~ 8%；
Above each component weight sum is absolutely.
Can also add in the formula material weight proportion of described welding backing block 1:
Starch 2 ~ 3%, manganese oxide 1 ~ 2%.
By above formula, the welding backing block 1 of the present invention under electric arc heat effect, the surface portion of appearance of weld groove 5
The slag that the soldered electric arc of raw material burns till can be combined together with flux material slag, and protection welding pool completes Welding Metallurgy mistake
Journey, reaches the effect of quality weld quality.
The color of described welding backing block 1 is brown brown.The raw material being adopted due to the present invention and proportioning are unique, therefore welding lining
The color of cushion block is in sepia, welding backing that is not only attractive in appearance but also being different from other purposes.
The cross section of described welding backing block 1 is square 3 and trapezoidal 4 combination, and described cross section top is square 3, under
Portion is trapezoidal 4, and described trapezoidal upper bottom 41 is than the bottom that 42 long and trapezoidal upper bottoms 41 are square 3 of going to the bottom.Horizontal stroke of the present invention
Section, refers to the cross section of the axis perpendicular to this spacer block 1, identical with the end surface shape of welding backing block 1, therefore in figure will
Drawing reference numeral is marked on end face, replaces cross section with end face.
Described square 3 top is provided with appearance of weld groove 5, described trapezoidal 4 42 groove line being provided with attachment centering of going to the bottom
6.Accurately say, appearance of weld groove 5 at square top axis, the groove line 6 of centering
Located at trapezoidal go to the bottom 42 axis at.So welding backing block 1 good looking appearance saves raw material again, and density is good, non-friable.
The manufacturing process of the welding backing block 1 of the present invention is to weigh up various raw materials by above-mentioned formula proportion to add suitable quantity of water, mixes
Conjunction is mixed thoroughly, and suitable mud, pugging are pressed into base substrate, burn till through high temperature after body drying.Subsequently, check qualified welding backing block
1 head and the tail connect into required length, are mounted on aluminum foil and adhesive tape 2.Draw centering red line in the axis of appearance of weld groove 5.Warp
Technical checking warehousing after passing is pending.
During use, on welding point during welding, tear off antiseized on the aluminum foil and adhesive tape 2 of welding backing block 1 both sides first
Paper 7.The axis that centering red line is directed at welding point is attached to welding point 8 back side welding backing 11, now, can be from welding point
8 fronts are welded, and reach the effect of single-sided welding two sides all molding.Slag on weld metal is easy to fall off, the weldering on weld seam
Ripple is well-balanced smooth.
Finally it should be noted that above example is only in order to illustrating technical scheme, rather than the present invention is protected
The restriction of shield scope, although having made to explain to the present invention with reference to preferred embodiment, those of ordinary skill in the art should
Work as understanding, technical scheme can be modified or equivalent, without deviating from the reality of technical solution of the present invention
Matter and scope.
