Use of hot melt butt welder
06 Aug 2018
Use of hot melt butt welder 1, welding preparation The preparation for welding is mainly to check whether the condition of the welding machine meets the working requirements. For example, check whether the fasteners in various parts of the machine are loose or loose; check whether the electrical connection of the whole machine is correct and reliable; check whether the hydraulic oil in the hydraulic tank is sufficient; confirm that the power supply matches the requirements of the machine; whether the heating plate meets the requirements (Whether the coating is damaged); trial operation of milling cutters and oil pump switches, etc. Then insert the slips with the same pipe specifications into the rack; set the temperature of the heating plate to the welding temperature (the welding temperature of the polyethylene pipe is 200~230 °C), and wipe the heating plate with soft paper or cloth alcohol before heating. Surface, but be careful not to scratch the PTFE release layer. https://www.chbu...
Hot melt butt welder The hot melt butt welder is a special welding equipment
01 Aug 2018
Hot melt butt welder The hot melt butt welder is a special welding equipment that applies hot melt butt joint technology to weld thermoplastic pipe fittings. The welding frame of the hot melt butt welder is separate from the operating system. The whole machine (automatic type, hydraulic semi-automatic type) is composed of hydraulic operation console, welding frame and fixture, electric heating plate and electric milling cutter. The manual type has no hydraulic system. The welded frame is made of high-strength aluminum alloy material, which is firm in structure, light and durable. The welding frame adopts a ferrule mica sheet pressing structure, and the positioning pipe is accurate, and it is easy to adjust the amount of misalignment. Introduction There are various forms of hot-melt butt welder. Users should choose according to the specifications of welded pipe, their own economic bearing capacity, the quality of operators and the management level of welding machine quality. According t...
Tungsten argon arc welding safety regulations
23 Jul 2018
1) The welding work site must be equipped with fire protection equipment, such as sand boxes, fire extinguishers, fire hydrants, buckets, etc. The flammable materials shall not be less than 5m away from the welding place. If the specified distance cannot be met, it can be covered with asbestos board, asbestos cloth, etc. to prevent Mars from falling into flammable materials. Explosive items shall not be less than 10m away from welding. The argon arc welding work site should have good natural ventilation and fixed mechanical ventilation to reduce the hazards of argon arc welding of harmful gases and metal dust. 2) Manual tungsten argon arc welding machine should be placed in a dry and ventilated place, in strict accordance with the instructions for use. The welder should be thoroughly inspected before use. Make sure there are no hidden dangers and then turn on the power. After the no-load operation is normal, the welding can be performed. Ensure that the welder is wired correctly and mu...
Daily maintenance and maintenance of welding machine

The electric welder uses the high-temperature arc generated by the positive and negative poles in an instantaneous short circuit to melt the solder and the material to be welded on the electrode to achieve the purpose of combining them. The structure is very simple, it is a high-power transformer. The welding machine can be divided into two types according to the type of output power, one is AC power; the other is DC. It is made by the principle of inductance. When the inductance is turned on and off, a huge voltage change is generated. The high-voltage arc generated by the positive and negative poles in the instant short circuit is used to melt the solder on the electrode to achieve the combination. The purpose of the welding machine can not be ignored during maintenance and maintenance. Electric welder routine maintenance 1. Check the welder output wiring specification, firm, and the outlet direction is close to vertical, and the angle with the horizontal must be greater than 70°. 2....
