What are the issues to pay attention to when welding high-pressure alloy steel pipe?

In the production process of high-pressure alloy steel pipe, it is necessary to solve them very well. To ensure the quality of laser welding of high-pressure alloy pipes, some matters must be taken into account. Let’s take a look at high-pressure alloy steel pipe. What are the issues to pay attention to when welding?

During the laser welding operation of high-pressure alloy pipes, it is essential to follow the specifications of the melting hole from beginning to end. The height of the melting hole poses a significant threat to the reverse formation of high-pressure alloy pipe welding. If the hole of the electric fusion pipe is large, it will cause ignition. Penetration or electric welding; Welding holes that pass through the clock head are very prone to defects such as lack of welding due to melting depth. In situations where the edges are blunt, gaps, welding current, and electrical level are skewed, the welding speed of high-voltage alloy pipes is important. Only in the general case of the above diameter, the arc is reduced, the rocker must be stable, and the welding speed must be uniform. Usually, do not extend the arc or implement a “pick up arc” position, and welding can be idealized in the opposite direction.

The reason for disassembling and replacing the welding wire of the high-pressure alloy pipe is to ensure that the bottom welding is straight, without welding protrusions, incomplete melting depth and dents, and the connection head continues to open. It is necessary to grasp the two stages of electric arc closing and interface. When closing the arc, slowly move the electric level to the left or right concave groove side, and then make the arc stable. Do not eliminate the arc of the concave groove core. That way, it can avoid the product workpieces on the back of the detection board from being folded up and the exhaust port.
