In modern industrial production, the welding process is of vital importance. Choosing the right welding machine is directly related to an enterprise's production efficiency, product quality, and cost control. There is a wide variety of welding machines on the market, each with different models and functions. To help enterprises accurately select the most suitable welding equipment, a detailed comparative analysis of several common welding machine models is presented below.
It has the capabilities of fully automated feeding, positioning, and welding. The XY - axis mold frame is driven by a servo motor through a synchronous belt. The walking step length and speed are precisely controlled by the control system. Operators only need to place and fix the materials on the mold frame. After starting the switch, under the precise control of numerical control programming, the equipment can walk alternately in the X and Y - axis directions according to the preset program, automatically complete the constant - point welding of each part, and return to the origin automatically after welding. During this period, operators can simultaneously prepare the materials for the next welding, effectively improving work efficiency and reducing labor costs.
Equipped with an intermediate - frequency inverter system, it significantly reduces spark splashing during welding, ensuring welding quality and reducing pollution to the working environment. The self - made pressure - applying cylinder has good follow - up performance and can compensate for the welding pressure instantly when the welding current is turned on, making the welded products more solid and the welding nuggets more aesthetically pleasing. In addition, the control program of this equipment can store multiple sets of product specifications. According to the process requirements of the mesh, the walking distance and alternate time of the mold can be flexibly set to ensure the accuracy of the welding position.

It has a pressure - applying speed adjustment function, allowing the operator to adjust the descending speed of the pressure - applying head at will to relieve the impact on the welded object during pressurization. It has an upward buffer speed, reducing mechanical impact, not only improving the service life of the cylinder body but also reducing noise. The filter cup of the air - circuit system is equipped with a protective device, which can prevent the splashing of debris when the cup is broken and protect it from external impact. The cup and the protective device are easy to install and disassemble, facilitating maintenance. It adopts a water - saving forced - cooling method, using circulating cooling water to avoid water waste and significantly reduce the amount of cooling water. The machine body structure is solid, with strong impact and vibration resistance, which can prevent the electrode head from sliding during pressurization and achieve stable welding. The main circuit adopts a high - power SCR contact - less switch and a water - cooled high - power thyristor element, with strong and stable output voltage and high reliability. In the primary current circuit, the secondary output of the main transformer uses multi - layer high - toughness and high - conductivity copper soft strips, connected in a V - shape, greatly improving the service life. The secondary output adopts an integrated direct - connection mechanism, minimizing power loss.
It is widely used in the spot welding and projection welding of carbon steel plates and stainless - steel plates, as well as in industries such as high - carbon steel saw blades, iron wire products, wire terminals, auto parts, stainless - steel products, low - voltage electrical appliances, hardware lighting, kitchen utensils, small household appliances, and small hardware.
Although different types of row welding machines have their own characteristics, they all have the ability to efficiently weld metal meshes. For example, the gantry - type row welding machine has a stable structure and can bear the welding of larger - sized meshes; the three - head intermediate - frequency inverter DC row welding machine has a stable welding current and good welding effect. Many row welding machines are controlled by a computer and a PLC programming controller, with a relatively high degree of automation.
During welding, it uses cycle adjustment to effectively reduce welding pollution. The welding pressure is usually adjustable to adapt to the welding of different - sized wires. Parameters such as the diameter of the warp wire and the pitch of the weft wire can be adjusted according to needs. Some equipment can also set different - sized mesh holes in the warp and weft directions on the same mesh. The welding transformers of some row welding machines adopt air - cooled or forced - water - cooled methods and are equipped with a flow - protection device to ensure the reliable and continuous operation of the equipment. The pressure of the welding pneumatic system is steplessly adjustable, which can quickly respond to changes in the specifications of steel bars, ensure a uniform welding pressure, and thus ensure the quality of all weld points.
