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
05 Jul 2018
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....
The use of hot melt butt welder
29 Jun 2018
1, welding preparation Welding preparation is mainly to check whether the condition of the welding machine meets the working requirements. Check whether the fasteners on each part of the machine are loose or loose; check whether the electrical circuit connection of the whole machine is correct and reliable; check whether the hydraulic oil in the hydraulic tank is sufficient; confirm the match between the power supply and the input requirements of the machine; if the heating plate meets the requirements (whether the coating is damaged); trial operation of milling cutters, oil pump switches, etc. Then install the slip with the same pipe size into the rack; set the temperature of the hot plate to the welding temperature (the welding temperature of the polyethylene pipe is 200~230°C). Before heating, wipe the hot plate with soft paper or alcohol. The surface, but be careful not to scratch the PTFE anti-stick layer. 2, welding Welding shall be performed in accordance with the parameters of ...
Introduction of hot melt butt welder
09 Jun 2018
Hot melt butt welding machine is a kind of special welding equipment that uses hot melt butt welding technology to weld thermoplastic pipe fittings. The welding frame of the hot melt butt welding machine is separated from the operating system. The whole machine (automatic type, hydraulic semi-automatic type) consists of hydraulic operation console, welding frame and fixture, electric heating plate, electric milling cutter and other parts. Manual type no hydraulic system. The welding frame adopts high-strength aluminum alloy material, which has a firm structure, light weight and durability. The welding frame adopts the compression structure of the card mica sheet to accurately position the pipe and make it easy to adjust the misalignment amount. The form of hot-melt butt welding machines is various. Users should select them according to the specifications of welded pipes, their own economic ability, the quality of operators, and the management level of welding machines. According to the...

About Welding Equipment Industry Status and Market Prospects
03 Apr 2018
With the modernization of industry forward, the domestic market demand for welding and cutting equipment increased year by year, in addition to foreign countries as there is already a lot of welding and cutting equipment is being used, so the CNC plasma cutting machine popularity subject to certain constraints, and our welding and cutting equipment technology and applications start late, forming a gap between supply and demand, leading to huge of welding and cutting equipment, particularly CNC plasma cutting machine is a potential market. According to statistics, in recent years, China's annual demand of about 50,0000units of welding and cutting equipment, and there are growing year by year trend, the economic development of the surrounding area and for us to show a good international market prospects. Current trends Welding equipment should be developed fully automatic, multi-function, high-power and high quality, such as orientation. 21 century, China's welding and cutting equipment ...
