Advantages of straight seam welder
Seam welding machines include horizontal seam welding machines and vertical seam welding machines. Horizontal welding machine is mainly used for welding the fuel tank of motor vehicles and the bottom of the oil cylinder, and vertical seam welding machine is mainly used for welding the cylinder side. If seam welding is successful, the welding must be tight and tight, and no oil or water can be leaked. Therefore, the output of the transformer of the seam welding machine must not be small, and because the seam welding is continuous welding, the transformer and the welding wheel must be tested, otherwise it is very easy to destroy.
First, the basic principles of direct welding machine equipment
The direct welding machine can be said to be a power ballast, divided into positive and negative. When the AC current is input, after the transformer changes the voltage, the ballast rectifier then outputs the switching power supply with reduced external characteristics. Switching on and off causes a great change in operating voltage.
Both sides ignite the electric isolation in the event of a short-circuit fault, and use the electric isolation to melt the stainless steel electrodes and welding materials. After water cooling, it exceeds the purpose of merging them. Welding transformers have their own characteristics. The external characteristic is that the working voltage drops sharply after the welding wire is ignited.
Key features of straight seam welding equipment:
1.The dynamic piano key clamping structure can be sorted closely along the two sides of the straight seam to ensure that the butt welds are evenly clamped within the entire welding length; the interval between the upper and lower piano keys can be adjusted;
2. The cantilever structure is used for the connection server. The two cantilever beams are welded and annealed to resolve the in-situ stress to ensure that the load-bearing beam is not deformed for a long time.
3. According to the thin and thick specifications of steel parts, gas or cylinder type can be selected to ensure sufficient clamping force and avoid thermal expansion during the entire welding process;
4. The welding mandrel is inlaid with copper tires, showing the welding back-gas maintenance effect; different welding methods are used for the production of heads or flat steel parts, which are more than one-sided and two-sided welding.
5. The DC servo motor driver and rack drive system are used for walking. The rail surface is cut and processed to ensure stable walking and reliable welding.
6, there are bronchial tubes and cables placed in the cable towline, the appearance is clean, neat and elegant, and to prevent the cable from disconnecting.
7. Straight seam welding of drums, cones, and splicing methods for stainless steel plates / stainless steel 201 / cold rolled steel plates / hot-dip galvanized plates / aluminum / copper and other metal materials The welding quality is stable and the welding rate is steplessly adjustable.
Third, the advantages of direct welding machine welding:
1.Easy to use, can adjust the main parameters of welding over a long distance
2.Electrical isolation is stable, splash is small, welding current output is stable, and welding is beautiful and generous
3. Low power output power, three-phase power output, low energy consumption, low noise, high energy saving and environmental protection.
4. There are many product applications, which can be widely used in round steel pipes, cables, aluminum, copper, and rare metals.
