(1) welding in the workplace must have fire safety equipment, such as sand boxes, fire extinguishers, fire hydrants, buckets and so on. Flammable materials from welding place not less than 5m. If you can not meet the specified distance, can be used asbestos, asbestos cloth, etc. properly covered to prevent Mars into flammable materials. Explosive materials from Welding Electrode place not less than 10 m. Welding workplace have good natural ventilation and fixed mechanical ventilation, reduce harmful gas and metal welding fume hazards.
(2) with manual argon arc welding tungsten should be placed in a dry ventilated place. Strict accordance with the instruction manual welding operation. Before using welding to conduct a comprehensive inspection. To determine the welder is not hidden, and then power. No-load operating normally before welding. To ensure proper welding wire, must be good, solid grounding in safety. Welding power source through, switch off the power supply control board, non-load flip a switch, to avoid burning switch contacts.
(3) The welding gun should always check the cooling water or gas supply systems work, and found that blockage or leakage should be immediately addressed to prevent the impact of the quality of welding torch and burned.
(4) welding personnel to leave the workplace or the welder when not in use, turn off the power. If the welder fails, by professionals for maintenance, repair should be ready against electric shock and other safety measures. Welding dust should be cleaned once a year.
(5) TIG welding machine high frequency oscillator of high frequency electromagnetic fields lead to the certain degree of dizziness, fatigue. Therefore, when welding high-frequency electromagnetic field to minimize the time, immediately cut off high-frequency arc ignition power. Aluminum Electrode torch and cable lines outside the application of soft metal shielding textiles (one end of the torch hose on the other end, the outside is not insulated). If the conditions should be replaced by the crystal frequency pulse arc arc.
(6) argon, the UV intensity of a great, easy to cause electric ophthalmia, arc burns, while ozone and nitrogen oxides irritate the respiratory tract. Therefore, the welder operator should wear a white canvas overalls, wearing masks, face shields and protective gloves, foot cover.
Mine use trusses supporting automatic molding and welding equipment, successful commissioning
Recently, developed by Lanzhou University of Technology with a mining supporting truss automatic molding and Welding Electrodes on the line about successful commissioning of production, marks the successful development of the domestic equipment, truss a major breakthrough in automatic molding technology.
Mine truss bracing is used extensively for mining, the current, automated production equipment such trusses in the country has not conducted research and development and manufacturing related organizations, foreign production truss equipment is confidential, so far, the domestic production of truss still use hand-molded and hand-soldering method. Jinchuan Group Co., Ltd. under the dragon's first mine, the three mines each year in the production process consumes a mine with a truss supporting about 18 million pieces entirely by hand for molding, assembly and welding. Sixty-seven workers can only do 70-80 a day, truss, low productivity, high cost, and production of trusses or different lengths, or welding is not strong, the quality can not be guaranteed. In response to these shortcomings, Lanzhou University of Technology Materials Science Professor Wang Xijing through scientific research, the Jinchuan Group Co., Ltd. has developed an automated truss forming and welding production lines, industrial production of truss.
