Abstract
The invention discloses manufacturing process for copper plated flux-cored wires, which belongs to the technical field of welding. Gaps of a flux-cored wire are in laser welding by the aid of the laser welding technology after the flux-cored wire is rolled, copper is plated on the surface of the flux-cored wire by the aid of a chemical copper plating method, the requirement that plating solution cannot seep into the flux-core wire during copper plating of the flux-cored wire is met, and a copper plated flux-core wire is obtained. The manufacturing process particularly includes longitudinal steel strip shearing; steel strip cleaning (connecting); U-shaped groove rolling; powder adding; forming; rough drawing; fine drawing; laser welding; electrolytic alkali washing; water washing; electrolytic acid washing; water washing; chemical copper plating; water washing; sizing polishing; wire winding; and packing and warehousing. The manufacturing process overcomes the shortcoming of easy rusting of an existing welding wire, wire conveying friction coefficient of a flux-cored wire is reduced during service by the aid of copper plating, the flux-cored wire is conveyed smoothly, loss of contact tubes is little, electrical conductivity of the flux-cored wire is high, and the flux-cored wire is favorable for welding.
Description
Technical field
The invention belongs to welding technology field, be specifically related to a kind of welding material.
Background technology
Present domestic flux-cored wire production technology is mature on the whole, but welding wire surface exposed be iron, its shortcoming is: iron-based is prone to get rusty, and causes welding wire short memory time; Welding wire in use wire feed coefficient of friction increases, and wire feed is had some setbacks, and the ignition tip loss is many; The welding wire electrical conductivity is low, is unfavorable for welding.
Summary of the invention
In order to overcome the deficiency of prior art, the present invention provides a kind of copper facing flux-cored wire manufacturing process, is prone to get rusty to solve the prior art flux-cored wire; Coefficient of friction is big in the solder wire convey process, and wire feed is had some setbacks, and the ignition tip loss is many; Electrical conductivity is low, and poor electric conductivity is unfavorable for problems such as welding.
The technical solution adopted for the present invention to solve the technical problems mainly is after the rolling completion of flux-cored wire, to utilize laser welding technology; Carry out laser weld to the slit of flux-cored wire; And then carry out copper coating through the electroless copper method; Satisfy welding wire and in the copper facing process, can not make plating bath immerse welding wire medicine in-core, obtain the copper facing flux-cored wire.Concrete manufacturing process comprises:
Steel band-slitting-cleaning (tape splicing)-roll U-lag-add powder-moulding-rough-finish draw-laser weld-electrolytic alkaline cleaning-water cleaning-cathodic pickling-water cleaning-electroless copper-water cleaning-sizing polishing-take-up-packing warehouse-in.
Said laser weld belongs to contactless welding, and operation process need not pressurize, but need to use inert gas in case the molten bath oxidation, and the present technique Laser Welding is formed the compound weldering of laser-MIG with the MIG weldering, realizes the non-oxidation welding, and hot input quantity is welded than MIG and greatly reduced simultaneously.Use neodymium (Nd) can produce the continuous single wavelength light beam of 1---8KW for the yttrium-aluminium-garnet crystal bar (Nd:YAG) that excites element.YAG laser, wavelength are 1.06um, can be connected to laser welding system through flexible optical fibre, and device layout is flexible, are suitable for throat thickness 0.5-6mm.When the flux-cored wire semi-finished product of rolling completion with the speed of 1-4m/s during through laser beam, laser is burnt to be adopted with positive out of focus LASER HEATING 50 ~ 200us, receives then on the I-beam wheel, has accomplished to become seamless flux-cored wire after seamed cored wire is welded.
Flux-cored wire after the welding has been accomplished the production of copper facing flux-cored wire through electrolytic alkaline cleaning (NaOH 40-200g/L, decomposition voltage 20-50V, electric current 100-500A), water cleaning, cathodic pickling (H2SO4 50-200g/L, decomposition voltage 20-50V, electric current 100-500A), water cleaning, electroless copper (H2SO4 50-200g/L, CuSO4 50-120g/L), water cleaning, sizing polishing, take-up, packing, warehouse-in.
Adopting good effect of the present invention is to have solved existing welding wire to be prone to the shortcoming of getting rusty, welding wire through copper facing make its in use the wire feed coefficient of friction reduce, make wire feed smooth and easy, the ignition tip loss is few; The welding wire electrical conductivity is high, is beneficial to welding.
