Abstract
The invention discloses a plastic part welding groove and a welding method. The plastic part welding groove comprises a first plastic part and a second plastic part, wherein the first plastic part comprises an upper welding face and a lower welding face; an upper groove is formed in the welding position of the upper welding face and the second plastic part; a lower groove corresponding to the upper groove is formed in the welding position of the lower welding face and the second plastic part; a truncated edge is arranged between the upper groove and the lower groove; and the upper groove and the lower groove are both V-shaped grooves. According to the plastic part welding groove, the upper groove is additionally arranged, so that the welding penetration is increased, and the welding seam strength is enhanced; the length of the truncated edge is reduced to the maximum extent, the penetration depth of base metal is increased, and an operator can conveniently observe the penetration condition of the lower groove, so that the welding quality is improved; and welding defects such as incomplete fusion are reduced, so that the qualified rate of welding seam quality is improved.
Description
technical field [0001] The invention belongs to plastic part welding technology, in particular to a plastic part welding groove and a welding method. Background technique [0002] In the existing welding technology, manual hot air welding is often used for welding PP plastic fillet joints, especially in the 40mm thick PP plastic plate fillet welding technology, such as figure 1 weld groove shown, figure 1 It is a schematic diagram of the welding groove of the existing welded PP plastic corner joint. The use of this kind of welding groove has the following shortcomings in the specific application process: [0003] 1) The electrode used in manual hot air welding has a certain arc, the groove is too sharp, and the electrode cannot completely melt into the groove, resulting in a certain gap between the base metal and the welding defect; [0004] 2) The design of the welding groove is not reasonable enough, and the melting depth of the base metal is not enough to effectively o...
