Embodiment

[0013] A composite welding process of carbon steel and high-speed steel, which is specifically carried out according to the following steps:

[0014] 1. Pre-welding treatment: carbon steel and high-speed steel are used for shaping treatment, after treatment, reagent cleaning, ultrasonic cleaning and high-temperature drying are carried out in sequence, and finally demagnetization;

[0015] 2. Welding: Combine the 2mm carbon steel and high-speed steel processed in step 1 through the fixture, and use continuous laser welding for welding under the protection of nitrogen. During the welding process, remove the welding slag with a vacuum cleaner and use a welding The smoke purifier removes the smoke and dust; Among them, the continuous laser welding adopts the parameters of power 2000W, light spot 0.3mm, thickness 2mm, welding speed 3000mm / min-4000mm / min. During the welding process, the welding speed can be changed in real time within the welding speed range speed;

[0016] 3. Post...

Abstract

The invention provides a carbon steel and high speed steel hybrid welding process. The carbon steel and high speed steel hybrid welding process comprises the steps of 1, pre-welding treatment; 2, welding: using the clamp to combine the carbon steel and the high speed steel processed in step 1, with the protection of inert gases using continuous laser welding to finish the welding work, in the welding process using vacuum cleaner to vacuum the welding slag, using welding gas cleaner to clean the gases; 3, post-welding treatment, which is the completion of the hybrid welding process of carbon and high speed steel. The present invention has the advantages that the use of continuous laser welding successfully overcomes the welding difficulty of high speed steel and accelerates the welding speed, shortens the welding procedure and simplifies the welding operation. At the same time the use of clamp helps to combine the carbon steel and the high speed steel together, thus avoids the low precision due to long term friction and improves the welding quality.

Description

technical field [0001] The invention relates to a welding process, in particular to a compound welding process of carbon steel and high-speed steel. Background technique [0002] Different welding methods have different welding processes, and the welding process is generally determined according to the material of the workpiece to be welded, the structure type of the weldment, and the welding performance requirements. At present, pulse welding is generally used for composite welding of carbon steel and high-speed steel, but this process is slow and has low precision, which affects the quality of welding. Contents of the invention [0003] The invention provides a high-speed and high-precision compound welding process of carbon steel and high-speed steel. [0004] A composite welding process of carbon steel and high-speed steel, which is specifically carried out according to the following steps: [0005] 1. Pre-welding treatment: carbon steel and high-speed steel are used...
