Semi-automatic welding equipment - Hui Hua Shi welding, automatic welding equipment, welding Huashi

Welding head: its role is to convert energy into output energy equipment welding welding heat, and continuously feeding welding material, while the head itself is moved forward, the welding. SMAW welding clamp used, with the welding melted down to be constantly fed manual welding, and move forward to form a weld. Automatic welding machine with automatic wire feeding mechanism, and organic head walking mechanism to move forward and make the head. Commonly used car and hanging head two kinds. Resistance spot welding and projection welding electrodes and welding head is pressurizing means for applying pressure on the workpiece and energized. Another seam welding actuator to drive the movement of the workpiece. When welding is required static and dynamic clamping mechanism clamps and fixtures, as well as moving the fixture and upset agency. ① Energy welding equipment: welding is used to provide the energy required. Commonly used in a variety of welding power, also known as welders. It's the no-load voltage of 60 to 100 volts, the working voltage of 25 to 45 volts, the output current is 50 to 1000 Ann. Elbow automatic welding equipment when SMAW - Hui Hua Shi welding, arc often change, causing the welding voltage. To enable stable welding current automatic welding equipment, welding power source used by external characteristics should be steep drop, that is, as the output voltage changes, changes in the output current should be small. Gas metal arc welding and submerged arc welding power source can be micro-level feature automatic welding equipment - Hui Hua Shi welding, its output voltage when the current changes little change. Generally arc welding power transformers, generators and DC arc welding rectifier. Welding transformer provides alternating current, broader application. DC DC arc welding generators, manufacturing is more complex, more and less efficient consumption of materials, there are gradually being replaced by arc welding rectifier trend. Welding rectifier is developed in the 1950s, DC arc welding power supply straight seam automatic welding equipment - Hui Hua Shi welding, using a silicon diode or thyristor rectifier for. 1960s with the emergence of high-power transistor transistor welding power source, can achieve high accuracy and excellent control performance, but higher costs. Resistance welding equipment welding energy resistance welding transformer is relatively simple, no-load voltage range of 1 to 36 volts, the current from a few thousand to tens of thousands of security. Equipped with this welding energy device called AC resistance welding machine welder. There are other low-frequency resistance welding machines, resistance welding machine DC pulse, capacitor discharge resistance welding machines and secondary rectification resistance welding machine semi-automatic welding equipment - Hui Hua Shi welding, automatic welding equipment, welding by Huizhou City Huashi Huashi welding Equipment Limited.
