Problems solved by technology

However, although the laser welding method does not require protective gas, due to the action of oxygen in the air, it will cause yellowing or blackening at or near the weld, and the yellowed and blackened area cannot be removed by grinding, which will affect the appearance and welding quality. seam quality

Abstract

The invention provides a stainless steel tube laser welding protection device which can blow protective gas to a weld joint conveniently during stainless steel tube end portion welding, avoid the oxidation discoloration phenomenon of a stainless steel weld joint area and improve the weld joint quality. The stainless steel tube laser welding protection device comprises a fixing jacket, the fixing jacket is symmetrically divided into a left section and a right section along the diameter, one side of the left section of the fixing jacket and one side of the right section of the fixing jacket areconnected through a hinge shaft, a plurality of air blowing holes are formed in the end portion of the fixing jacket in an annular array mode, and a groove is formed in the peripheral wall of the fixing jacket and communicates with the air blowing holes. A sealing cover plate is arranged at an opening of the groove, and an air pipe connector is arranged on the end face of the sealing cover plate.

Description

technical field [0001] The invention relates to the technical field of stainless steel tube processing equipment, in particular to a laser welding protection device for stainless steel tubes. Background technique [0002] Household water pipes usually use PPR pipes or aluminum-plastic pipes. Among them, aluminum-plastic pipes are once popular household water pipes. Their disadvantages are that thermal expansion and contraction will cause misalignment of the joints and cause leakage. At present, aluminum-plastic pipes have been gradually eliminated. Although the PPR pipe has very stable leak-proof characteristics and the material is environmentally friendly, after a long period of use, the inner wall of the PPR water pipe will be seriously polluted again, and it is easy to breed bacteria and Legionella, which is not conducive to the health of users. As a water pipe with excellent performance, the stainless steel pipe itself has become the preferred water pipe for healthy home...
