According to the copper-clad steel tube, the processing speed, particularly the speed of the welding step, is increased, and the strength and the corrosion resistance of the material are guaranteed.
Description
Technical field
The present invention relates to a kind of copper-clad steel pipe of processing through high-speed welding, relate in particular to a kind of copper-clad steel pipe that makes through the lead welding of high speed electric arc.
Background technique
At present, global copper resource reduces day by day, and the high always enterprise of copper price is not down; The refrigerator, the Air-conditioning Enterprise that belong to copper pipe consumption rich and influential family; Seeking cheap, reliable quality substitute always, price competitiveness is being arranged, also at the various new products of active development for making product.Various new technologies, new process, new material emerge in an endless stream, and at present, on air-conditioning, bring into use various copper pipe substitute materials.
The copper-clad steel pipe adopts advanced metal composite processing technique, coats at the Precision Seamless Steel Tubes inner and outer surface to form, and makes between steel and the copper and form interatomic the combination, has possessed the corrosion-resistant and oxidation resistance of copper, and has had following characteristics:
1, the Copper Clad Steel pipe has good anti-corrosion, and steel is more perishable than copper under the normal condition, but because the steel in the copper-clad steel pipe is coated by copper is complete, has improved steel and be prone to oxidation, the characteristic of corrosion.
2, the copper-clad steel pipe adopts advanced technologies, and the combining closely of its copper and steel can be according to the actual use condition of user, but processing is crooked or once more moulding also hot flame weld, its surperficial copper can not come off, and has kept the character of copper pipe.
3, to have a relative cost low for the Copper Clad Steel pipe, and price is relatively stable, and it is expensive to overcome copper pipe, and the price unstability.
In the manufacturing of copper-clad steel pipe; Need through production technologies such as tube producer uncoiling and welding, however traditional induction welding welding method can't the copper-clad steel pipe be welded because the fusing point of copper is lower than carbon steel; Copper steel dissolves the back and forms fully not solid solution; Therefore how the steel in guaranteeing the copper-clad steel pipe fully by copper under the coating condition, will get up through the welding of longitudinal seam of the copper-clad steel pipe behind the plate bending rolls roll bending, will be a main difficult problem that solves the extensive use of copper-clad steel pipe.
Summary of the invention
The object of the present invention is to provide a kind of copper-clad steel pipe of processing through high-speed welding, it can realize the slitless connection to the copper-clad steel pipe, and guarantees that the steel in the copper-clad steel pipe is coated by copper fully.
The present invention has adopted following technological scheme: a kind of copper-clad steel pipe of processing through high-speed welding; It is characterized in that its steel layer thickness is 0.6mm, the copper layer thickness of steel laminar surface is 50 μ m; The welding longitudinal joint is 0.8-1.0mm, and said copper-clad steel pipe is made by following steps:
1) on the single surface of 0.6mm thick carbon steel plate through the copper layer of mechanical press last layer 50 μ m;
2) through tube producer this Copperplated Steel is formed the copper steel composite pipe, exist this moment along the axially extended longitudinal joint of pipe;
3) add and fill material and adopt copper and copper alloy welding wire, arc welding process adopts the cold metal transition, and welding speed adopts 6m/min, and protection-gas welding adopts pure argon, and the longitudinal joint gap control is between 0.8-1.0mm; Longitudinal joint to through the copper steel composite pipe of plate bending rolls aftershaping carries out the high-speed and continuous welding.
Compared with prior art; The high speed electric arc lead welding method of copper-clad steel pipe of the present invention has: 1. adopt copper and copper parent metal to connect together as the copper layer of lead material with longitudinal joint; Realize that the steel in the copper-clad steel pipe is coated by copper fully; Guarantee that liquid can't infiltrate in the steel, and weld strength has reached and adds the intensity of filling material and have good anti-corrosion; 2. existing high-speed welding technology, protection gas adopts ternary or quaternary gas more, and the present invention adopts the shielding gas of pure argon as High Speed Welding, and the with low cost and 5-10 that can reach conventional inert-gas arc welding welding speed is doubly; 3. this electric arc lead welding method can make carbon steel not melt, and the fusing of copper layer stoped the generation of copper steel intermetallic compounds effectively, guaranteed welding quality; 4. cold metal transition welding method has reduced hot input quantity, has reduced the amount of deformation of postwelding workpiece effectively.
Embodiment
The application is through a large amount of experiments; Selected following preferred step and parameter, promptly a kind of copper-clad steel pipe of processing through high-speed welding is characterized in that; Its steel layer thickness is 0.6mm; The copper layer thickness of steel laminar surface is 50 μ m, and the welding longitudinal joint is 0.8-1.0mm, and said copper-clad steel pipe is made by following steps:
1) on the single surface of 0.6mm thick carbon steel plate through the copper layer of mechanical press last layer 50 μ m;
2) through tube producer this Copperplated Steel is formed the copper steel composite pipe, exist this moment along the axially extended longitudinal joint of pipe;
3) add and fill material and adopt copper and copper alloy welding wire, arc welding process adopts the cold metal transition, and welding speed adopts 6m/min, and protection-gas welding adopts pure argon, and the longitudinal joint gap control is between 0.8-1.0mm; Longitudinal joint to through the copper steel composite pipe of plate bending rolls aftershaping carries out the high-speed and continuous welding.
