Problems solved by technology

In order to ensure the quality of the workpiece, many processing units have to allocate special personnel to deal with these weld bumps on the surface of the workpiece. It is very difficult to clean and process, and the man-hours are long and labor-intensive. Sometimes even metal cutting is required to remove them.

Embodiment 1

[0009] Put Shuangfei powder and water in a container at a weight ratio of 1:1000 and mix them evenly.

[0010] On the surface around the welding position of the workpiece, apply the mixture of Shuangfei powder and water, air-dry and then weld; finally, clean up the welding slag and complete.

[0011] Small workpieces can be directly immersed in the mixture, completely immerse the welding area in the container, take it out to air dry, and then weld.

Embodiment 2

[0013] Put Shuangfei powder and water in a container at a weight ratio of 1:50 and mix them evenly.

[0014] On the surface around the welding position of the workpiece, apply the mixture of Shuangfei powder and water, air-dry and then weld; finally, clean up the welding slag and complete.

[0015] Small workpieces can be directly immersed in the mixture, completely immerse the welding area in the container, take it out to air dry, and then weld.

Embodiment 3

[0017] Put Shuangfei powder and water in a container at a weight ratio of 1:500 and mix them evenly.

[0018] On the surface around the welding position of the workpiece, coat the mixture of Shuangfei powder and water, air-dry and then weld; finally, clean up the welding slag and complete.

[0019] Small workpieces can be directly immersed in the mixture, completely immerse the welding area in the container, take it out to air dry, and then weld.

Abstract

The electric welding process with simple welding slag elimination includes the steps of painting mixture fluid comprising double ground powder and water to the areas around welded parts in the workpieces, air drying, welding and eliminating welding slag. The mixture fluid comprising double ground powder with coarse whiting as the main component and water in the weight ratio of 1 to 100-1000 can form one coating on the surface of the welded workpieces, and the coating not affected by the welding slag makes the welding slag no smelting to the areas around welded parts in the workpieces and easy to eliminate. The present invention has greatly raised production efficiency.

Description

technical field [0001] The invention relates to a welding process, in particular to an electric welding process which is easy to remove welding slag. Background technique [0002] There has always been a problem in electric welding processing that it is difficult to remove welding slag. The temperature of the arc during electric welding can reach 2000-6000°C. If it is welding steel, its melting point is 1515-1538°C. The temperature at which the welding slag splashes to the surface of the workpiece is about 600-1800°C according to the length of the stroke and the temperature of the environment. between. Sometimes the temperature of the liquid welding slag will be higher than the melting point of the material. After splashing on the surface of the workpiece, it will melt the surface of the workpiece and form a weld bump on the surface of the workpiece that is difficult to remove. In order to ensure the quality of the workpiece, many processing units have to allocate special ...
