Please ask how to ensure welding accuracy from the perspective of process or equipment

Laser welding is not a commonly used welding method, if you put aside the welder technique factor, the current GTAW is TIG is better, argon arc welding is very beautiful, now a lot of high-quality pipeline welding is used full argon, of course, sometimes you can also consider using argon arc priming with two guarantees to fill the cover, but also GTAW + GMAW combination, so that the efficiency is higher! In fact, for the welding of the structure, MAG welding is generally used, such as the structural beam, etc., in addition, we must do a good job of appropriate welding process qualification before construction!

Laser welding equipment is more expensive about two million, generally used for butt welding, high welding efficiency, stable quality, if you can ensure that the equipment capacity is full, the cost of laser welding is lower than the cost of manual welding. It's just that the one-time investment is larger.

Reliable welding tooling can ensure welding accuracy, and the thermal deformation of the welding process can be eliminated by adjusting the tooling.

To ensure high precision of welding, some costs will generally be increased, such as anti-deformation method, rigid fixation method, and post-welding correction method, which will increase the processing time and increase the processing cost. Each welding method has its own advantages and disadvantages, to choose welding methods for different workpieces and use requirements, and finally people play the most important role, please a welding engineer, let him develop a more detailed welding process for you, from the welding process and equipment and technology and other aspects to ensure welding accuracy.

1. Automatic welding is mostly used; Use welding tooling more; Conduct more technical training for welders.

2. Not very clear.

3. Only increase the depreciation of fixed assets.

1. Strengthen support. It can be used as a tic-tac-toe support. A circular support can be welded, similar to a pipe head.

Water-cooled cooling. Immerse the lower part in water with the solder side facing up. In the right position, add water inside the circular support.

There must be no water at the weld. When welding, multiple places are welded at the same time or the position is switched to weld. If the accuracy cannot be achieved after welding, it can be easily machined.

2. Do a good job of supporting the welding edge before it is boring. At this time, the deformation is integral, and the force is applied inward, and it is easy to achieve rigidity control. After welding, it is roasted on the non-welded surface with fire to reduce stress. The side plates are welded together and the supports are removed, which can meet the requirements.

Silver bending welding: It can also be written as "welding" or welding, welding, which is a processing technology and connection method in which two or more materials (the same or dissimilar) are heated or pressurized, or both are used together to produce atomic bonding between two workpieces. Welding has a wide range of applications and can be used for both metals and non-metals.

1. Strengthen support. It can be used as a tic-tac-toe support. A circular support can be welded, similar to a pipe head.

Water-cooled cooling. Immerse the lower part in water with the solder side facing up. The position is right, and the hole water is added in the round and wide orthogonal support.

There must be no water at the weld. When welding, multiple places are welded at the same time or the position is switched to weld. If the accuracy cannot be achieved after welding, it can be easily machined.

2. Do a good job of support before welding. At this time, the deformation is integral, and the force is applied inward, and it is easy to realize the rigidity control and imitation. After welding, it is roasted on the non-welded surface with fire to reduce stress. The side plates are welded together and the supports are removed, which can meet the requirements.

Welding: It can also be written as "welding" or welding, welding, and is a processing technology and connection method in which two or more materials (the same or different) are heated or pressurized, or both are used to produce atomic bonding between two workpieces. Welding has a wide range of applications and can be used for both metals and non-metals.

Laser welding also has very high requirements for weldment assembly accuracy, such as workpiece assembly accuracy or beam positioning accuracy can not meet the requirements, it is easy to cause welding defects, so good and accurate clamping technology is the guarantee of laser welding.

Ordinary welding requires the matching gap between the welded parts to be about 2mm, while the ideal situation of laser welding is that the matching gap is as small as possible, and the matching gap between the welded parts is usually controlled in the production of body-in-white.
