Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 5, a welding process for improving the surface quality of a shielding hose is realized by the following steps:
firstly, sleeving a positioning ring 3 on a shielding hose and positioning;
the positioning ring 3 comprises a hollow cylinder body 3-1, one end of the hollow cylinder body 3-1 extends to the outer periphery to form an annular boss 3-2, a circular through hole 3-3 is formed in one side of the hollow cylinder body 3-1, and the hollow cylinder body 3-1 is sleeved on the periphery of the shielding hose;
step two, respectively winding glass cloth 4 at the periphery of the shielding hose positioned at two sides of the positioning ring 3 for protecting the shielding hose, wherein the winding sequence of the glass cloth 4 at two sides is to wind one side of the positioning ring 3 with the annular boss 3-2 firstly and then wind one side without the annular boss 3-2, and ensure that the glass cloth 4 at two sides tightly clamps the positioning ring 3;
adjusting the horizontal angle of the shielding hose to enable one side, provided with the annular boss 3-2, of the positioning ring 3 to be at a low position, enabling the other end of the positioning ring to incline upwards, and keeping an included angle alpha between one side, provided with the annular boss 3-2, of the positioning ring 3 and a horizontal plane to be 5-10 degrees;
a vice, a metal block with different heights or a specific clamp can be used for adjusting the angle of the shielding hose and positioning the positioning ring in the first step;
welding the positioning ring 3, and injecting solder between the positioning ring 3 and the shielding hose from the through hole 3-3 for welding, wherein the flow direction of the solder flows from one side of the positioning ring 3 without the annular boss 3-2 to one side of the annular boss 3-2 instead of flowing out from two sides of the positioning ring 3, and when the solder flows out of the positioning ring 3 at one side of the annular boss 3-2, the solder only remains on the end face of the boss of the positioning ring 3 and cannot flow to the surface of the shielding hose due to the protection of the glass cloth 4;
and fifthly, filling the positioning ring 3 with the to-be-welded materials, detaching the glass cloth 4, cleaning the surface of the shielding hose by adopting alcohol, and polishing the residual welding materials on the end face of the annular boss 3-2 of the positioning ring 3 to complete the welding of the positioning ring 3 and the shielding hose.
According to past experience, the heat affected zone of a product is about 15mm when the product is brazed through an original welding process, and the axial winding length d of the glass cloth 4 is more than or equal to 20 mm. The winding mode of the glass cloth 4 is not limited, but the winding is firm and smooth.

The shielding hose comprises a stainless steel corrugated pipe 1 and a stainless steel braided hose 2, wherein the stainless steel braided hose 2 is coaxially wrapped on the periphery of the stainless steel corrugated pipe 1.
The solder is copper. When the positioning ring 3 is welded, the stainless steel braided hose 1 needs to be soaked, the hose is of a braided structure, and solder flows to the stainless steel corrugated pipe from gaps of the hose, so that copper welding with good welding fluidity is selected to enable the positioning ring to be firmly welded with the stainless steel corrugated pipe.
After the welding is finished, the wound glass cloth can generate a yellowing phenomenon, and the glass cloth is only needed to be detached, and the hose on the surface of the shielding is cleaned by alcohol, so that no excess is left; only the end face of one side of the positioning ring with the step face needs to be polished, so that the process of polishing the surface of the shielding hose is reduced; the heat affected zone at two sides of the positioning ring can be controlled within 5mm, and the surface is only slightly oxidized, thereby improving the surface quality and the production efficiency.
