Jianglong Intelligent Obtained The Patent For Inverter Carbon Dioxide Gas Shielded Welding Machine With Long Service Life

Jianglong Intelligent obtained the patent for inverter carbon dioxide gas shielded welding machine with long service life

There is a secondary welding machine. Its shell cannot withstand vibrations, and the internal plates are burned due to the accumulation of a large amount of dust. Carbon dioxide gas shielded welding (secondary security welding) riveting processing . This situation is particularly difficult in the riveting and welding processing workshop. In November 2025, a company that provides Internet services in Suzhou obtained a new patent. This patent uses shock absorption and isolation heat dissipation, which blocks these two problems together.

The shock-absorbing component is attached to the shell

On the outer wall of the main body of the welding machine, a set of shock-absorbing components is attached. The main function of this thing is to absorb the impact and vibration from the outside, because in the riveting and welding processing workshop, the welding gun often hits the workpiece and the welding machine is bumped. According to the past situation, once the casing is hit, the inverter board and power board installed inside are more likely to loosen or even break directly. But now because of this layer of buffering structure, The sturdiness of the overall structure has been significantly improved.

The design idea is very straightforward, that is, without changing the power and welding parameters of the welding machine itself, only adding a protective shell on the outside. For riveting and welding masters who need to travel to the construction site all year round and frequently change workstations, this solution can directly improve the durability of the equipment, thereby further reducing the frequency of equipment replacement.

Ventilation partitions cut the inner cavity

The heat dissipation component has a core part, which is the ventilation partition. The purpose of this ventilation partition is to divide the space inside the welding machine. The result is two separate areas. One of these areas is the heat dissipation channel.

The other area is the circuit area. There is no interconnection between the two areas. So the situation is like this, the cooling air flow can only flow along the heat dissipation channel. It won't touch the inverter board at all. It also won't touch the power strip.

The application date is set for November 2025, and the authorization announcement number has been publicized by the National Intellectual Property Office. The partition completely separates wind and electricity. This structure is not particularly common in existing secondary welding equipment. This is the main innovation in this patent.

Back-shaped air inlet and louvers for air outlet

At both ends of the heat dissipation channel, one section is connected to the zigzag air inlet, and the other section is connected to the louver air outlet. The air flow will be sucked in from the air inlet, then pass through the heat dissipation channel, and finally blown out from the louver , thus forming an isolated air path. During the entire process, the air will not enter the circuit area, so the circuit board will not be directly blown by the heat wave.

This zigzag structural design makes the ventilation area become very large. As for the function of the blinds, it is to prevent rainwater and larger particles of debris from pouring directly inside. Facing the rainy season in the south, or for riveting and welding workshops with a lot of dust, this air duct system is much more reliable than the traditional open heat dissipation method.

Dust and impurities are blocked in the channel

The current secondary welding process actually uses carbon dioxide as the protective gas. During welding operations, a large number of slag particles and metal powder will continue to be produced in the working environment. Once this kind of dust adheres to the surface of the circuit board and accumulates over time, it will cause the insulation performance of the circuit board to be reduced.

Under this condition, short circuit faults can easily occur in the circuit. At the same time, the problem of virtual soldering will also occur. A tripping of the power supply system may also occur. The overall service life of the entire device is therefore severely affected and significantly shortened.

After the isolation air path is established, the airflow carrying dust will only circulate back and forth in that heat dissipation channel. The louver air outlet is responsible for arranging the dirty air to the outside for exhaustion. As for the circuit board, it always stays in a relatively clean circuit area. In this way, the reliability is increased and the failure rate is naturally reduced.

Patent layout of Suzhou companies

According to the information disclosed on the Tianyancha platform, the company was established in 2016. The registered location is carbon dioxide gas shielded welding (secondary shield welding) riveting and welding processing in Suzhou. Its main business scope is the Internet and related service fields. Its registered capital is 4 million yuan. At the current stage, the company has two trademark records and 40 patent information under its name. It also holds three administrative licensing projects.

The possession of forty patents clearly shows that the company is continuing to accumulate technology in the subdivided field of welding equipment. Secondary protection welding is one of the most commonly used welding methods in riveting welding. Everyone focuses on it to make structural improvements and measures to improve heat dissipation performance. At present, the market space is still huge.

What does it mean for the riveting and welding shop?

For those manufacturers engaged in secondary welding and riveting welding, the core competitive advantage of this welding equipment is that it is very durable and not easy to damage the circuit board. Because it has an external shock-absorbing device to withstand bumps and bumps at the construction site, and an internal isolation and heat dissipation design to prevent dust from entering the workshop, its service life is significantly longer, and the cost of maintenance is reduced accordingly.

Of course, the actual situation now is that the patent has just been authorized, and mass production issues and specific prices have not yet been announced. If you bosses have any need to replace equipment, you can wait a moment and continue to pay attention to the follow-up news. At least from the perspective of technical solutions, this time it has indeed solved two long-standing pain points at the same time.

In your workshop, have the two protected welding machines ever burned out the boards due to dust? You can talk about it in the comments. If you think this statement is useful, give it a like, and then forward it to your friends who are doing riveting and welding processes.
