As shown in fig. 1 to 3, a stainless steel ignition section welding bolt comprises a screw rod, wherein one end of the screw rod is provided with an external thread 3, the other end of the screw rod is provided with an arc ignition part, one end of the screw rod is provided with an external thread along the length direction of the screw rod, and the other end of the screw rod is provided with an arc ignition part. The smooth rod comprises a melting part 21 and a ceramic ring installation part 22, the smooth rod is adjacent to the external thread, the melting part is arranged above the ceramic ring installation part, and the lower part of the ceramic ring installation part is connected with the external thread part of the screw rod. The melting part is used for being fixed with the welded object after being melted during welding, and the ceramic ring is arranged outside the ceramic ring mounting part. The arc striking part comprises a fluxing part 11 and an arc striking knot 1, one end of the fluxing part 11 is connected with the screw, and the arc striking knot 1 is arranged at the end head of the other end of the fluxing part 11. The length of the external thread of the screw is 3.6-3.75 times of that of the smooth rod, and the screw is made of 304 stainless steel materials.

As shown in fig. 2, the smooth rod and the external thread have the same pitch diameter, so that when the external thread is processed on the screw, the size of a blank of the thread rolling thread of the thread can be conveniently controlled, and secondary processing is not needed. The cross section of the fluxing part 11 is in a trapezoid shape, the included angle between the left side waist and the right side waist of the trapezoid of the arc striking part is A, the included angle A is 140 degrees, the arc striking knot 1 is arranged in the middle of the upper bottom edge of the trapezoid shape, and the lower bottom edge of the fluxing part and the end of the screw are designed in an integrated mode. The arc striking structure is characterized in that a mounting hole is formed in the fluxing part, the arc striking knot is fixed in the mounting hole, a widening hole is formed outside the mounting hole, the diameter of the widening hole is larger than that of the mounting hole, and in the pressing stage after the arc striking knot is mounted to the mounting hole, the arc striking knot deforms and the deformed part is filled in the widening hole.

As shown in fig. 3, the utility model discloses still include porcelain ring 4, porcelain ring 4 sets up on the porcelain ring installation department 22, porcelain ring 4 is the ring form, 4 internal diameters of porcelain ring are greater than smooth rod external diameter. After the porcelain ring is installed on the porcelain ring installation department of screw rod, the external screw thread of melting portion and screw rod is separated to the porcelain ring during welding, and the porcelain ring plays isolated high temperature's effect simultaneously, makes can not produce deformation because of welded high temperature by welding object 5. Porcelain ring just no longer continues the welding after melting off the melting portion when making the welding on the one hand, plays limiting displacement, and the liquation that melts off flows into porcelain ring and porcelain ring installation department when on the other hand makes the welding and by between the welding object, knocks off the welding slag like this of porcelain ring after using outward and can not splash to the scar that forms after having welded does not have hard edges and corners, can not scratch the people.

The utility model discloses a main improvement point lies in increasing smooth section on the screw rod, increases one section simultaneously and makes porcelain ring installation department and melting mutually independent in smooth section, and the melting is used for the butt fusion, and porcelain ring installation department is used for installing porcelain ring, is used for thermal-insulated, moulding and prevents the effect that the slag splashes behind the installation porcelain ring. After porcelain ring installation department and melting portion mutually independent set up, the welded screw rod part has been increased during the butt fusion, even during the use the utility model discloses the melting portion too short can not satisfy firm welded effect, also can continue the porcelain ring installation department of butt fusion part in order to compensate, but this technical problem can not be solved to the structure of welding portion and porcelain ring installation department as an organic whole in the current welding bolt. The reason why the existing welding bolt is provided with the welding part and the ceramic ring installation part in an integrated structure is to save materials, and the existing technology is based on the idea that the bolt with the ceramic ring installed outside and inside can still be used for welding, but the arrangement mode has inherent defects. In addition, a fluxing part is added between the melting part and the arc striking junction. The arc striking knot, the fluxing part, the melting part and the ceramic ring mounting part are arranged in sequence, and the arc striking knot, the fluxing part and the melting part are burnt and welded in sequence when the ceramic ring is used.

A fluxing part is arranged between the melting part and the arc striking junction of the screw, the cross section of the fluxing part is designed in a trapezoid shape, the joint of the fluxing part and the arc striking junction is the upper bottom edge of the trapezoid, and the cross section area of the fluxing part from the arc striking junction to the melting part is gradually increased. When in welding, the arc striking knot is firstly ignited, then the upper bottom edge with a smaller cross section of the melting-aid part is melted due to the beginning of welding, the melting-aid part is gradually welded after the upper bottom edge is melted, and then the melting-aid part is slowly melted to the screw rod, and the melting-aid part with the smaller cross section is easy to melt, and the temperature after melting is higher, so that the melting-aid part and the screw rod can be favorably melted. The screw rod comprises smooth section and the screw thread section above, and traditional screw rod smooth section only has porcelain ring installation department, does not have melting portion, sheathes the screw rod in the direct butt fusion porcelain ring behind the porcelain ring during the butt fusion. The utility model discloses increase one section melting portion on porcelain ring installation department to melting portion is the melting section, and the metal liquid after the melting flows into between porcelain ring and the porcelain ring installation department again and flows in between by welding object and the screw rod. Traditional screw rod does not establish the melting portion or with the melting portion with porcelain ring installation department integral type design back, and the insufficient welding of welded metal liquid is firm inadequately, because the porcelain ring only plays thermal-insulated and prevents the effect that welding liquid splashes, and does not have to carry out moulding to welding liquid and lead to the scar shape of screw rod head various, influences the pleasing to the eye japanning operation that still influences after the welding promptly behind the welder, and the scar is pricked easily or the scratch people simultaneously.

The above embodiments are only used for illustrating the present invention, and not for limiting the present invention, and those skilled in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention, so that all equivalent technical solutions also belong to the scope of the present invention, and the protection scope of the present invention should be defined by the claims.
