[Shenzhen laser welding machine] stainless steel sensor ring seam automatic laser welding machine

Biography sensor is a high-precision detection equipment, there are strict requirements in military and aerospace industries. The sensor must be rigorously tested before application. Whether the sensor is high-tech value-added depends on high technology and technical processing.

Due to environmental conditions, the sensor requires a metal package to be generally sealed, such as pressure sensors, Hall sensors, photoelectric sensors, temperature sensors, and other sensors containing sensitive components and integrated circuits, filled with inert gas or vacuum to isolate the outside world, the required pressure , air tightness, welding strength and leakage rate. In this process, Shenzhen laser welding machine has high welding quality requirements and small deformation, which will not damage internal components and circuits.

Nowadays, the main methods of sealing sensor welding are resistance welding, hydrogen arc welding, plasma arc welding, electron beam welding, ultrasonic welding, vibration friction welding, hot plate welding, laser welding, etc. Compared with other methods, stainless steel sensor The ring seam automatic laser welding machine has the following advantages:

What are the process characteristics of laser welding machines in sensor welding?

( 1) High aspect ratio. The weld is deep and narrow, and the weld is bright and beautiful.

( 2) Minimum heat input. Due to the high power density, the melting process is extremely fast, the input workpiece heat is very low, the welding speed is fast, the thermal deformation is small, and the heat affected zone is small.

( 3) High density. During the formation of the weld, the molten pool is continuously stirred and the gas is easily released, resulting in the formation of a non-porous penetration weld. The high cooling rate after welding is easy to make the weld microstructure fine, and the weld strength, toughness and comprehensive performance are high.

( 4) Strong welds. High-temperature heat source and sufficient absorption of non-metallic components produce purification, reduce impurity content, change inclusion size and its distribution in the molten pool, no electrode or filler wire is needed in the welding process, and the melting zone is less polluted, making the weld The strength and toughness are at least equivalent to or even exceed the parent metal.

( 5) Precise control. Because the spotlight is small, the welding seam of Dongguan laser welding machine can be positioned with high precision, the beam is easy to transmit and control, and the torch and nozzle need not be replaced frequently, which significantly reduces the stop assist time, high production efficiency, no inertia of light, and can also be Emergency stop and restart at high speed.Complex components can be welded with self-controlled beam movement technology.

( 6) Non-contact, atmospheric welding process. Since the energy comes from the laser, the workpiece has no physical contact, so no force is applied to the workpiece. Magnetic and air have no effect on the laser.

( 7) Since the average heat input is low, the machining accuracy is high, the rework cost can be reduced, and the laser welding operation cost is low, thereby reducing the workpiece cost.

( 8) It is easy to automate and effectively control the beam intensity and fine positioning.
