Plasma powder surfacing is our self-developed device has a metal surface modification completely independent intellectual property rights, the welding process is to improve the metal surface wear resistance, corrosion resistance and impact resistance of other properties of the effective techniques. DML-V02 works: high temperature plasma powder surfacing is a plasma arc as a heat source, the application of plasma arc generated by the alloy powder and the substrate surface is rapidly heated and melted together, mixing, diffusion, solidification, plasma beam after leaving the self-excited cooled to form a layer of high-performance alloy layer in order to achieve enhanced and welding parts of the surface hardening process, due to the arc temperature plasma arc has a high heat transfer rate, good stability, penetration controllable by adjusting the relevant heap welding parameters, surfacing layer thickness, width, hardness freely adjusted within a certain range. After the formation of plasma powder surfacing between the base material and surfacing materials integration interface, high bonding strength; surfacing dense, corrosion and abrasion resistance; dilution matrix material and surfacing material is reduced, small changes in material properties; using the powder as a surfacing material alloy design to improve selectivity, in particular welding smooth refractory material of the workpiece to improve the wear resistance, high temperature corrosion resistance. DML-V02 technical advantages: 1, surfacing alloy cladding layer and the base takes the shape of the workpiece metallurgical bonding, combined with high strength; 2, cladding welding speed, low dilution rate; plasma arc welding can be controlled at a dilution rate of 5% a 10% or lower. 3, dense surfacing layer, forming beautiful; welding process is easy to realize mechanization and automation; 4, the metal parts of the surface rust and oil without complicated pre-treatment process, direct plasma welding; 5, and other plasma spray device structure is simple, energy-saving and easy to operate, easy maintenance and maintenance; 6, plasma arc, high temperature, concentration of energy, good stability, residual stress in the workpiece and cause little distortion. 7, good controllability. By changing the power to change the structure size gas type, flow and nozzle to regulate plasma arc atmosphere, temperature and other parameters of the arc, in order to achieve efficient and automated production, improve labor productivity. 8, using a wide range of materials. Restrictions surfacing alloy powder as cladding material, without casting, rolling, Roberts and other processing can be configured alloy powders with different compositions based on different performance requirements, especially for those difficult but easy-to-silk-resistant hard milling run-gold, to obtain the desired properties of the surfacing layer. DML-V02B Surfacing System Configuration: (1) DML-V02B host (power 4KVA) --- 1 units (2) Belt precision powder feeding system ------ 1 set (3) plasma powder welding gun (100A ) ---- 1 (4) cooling circulating water tank -------- 1 station DML-V02B host parameters: input power AC220v plasma output current range 1-100A laser imitation current range 2-200A rated power 4KVA pulse 10-990ms time interval 0.1-1s rated load voltage 85V 30V 70% load factor load voltage pilot arc voltage 20V 87V weight 50KG maintenance volume 90 × 60 × 150 dilution ratio 5% -10% CT-10 Cooling circulating water tank parameters: maximum capacity 10L 220V input power rated power 135W maximum flow rate of 20L/min surfacing double circulating cooling air 4 main technical parameters: plasma gas flow adjustment range ------- 0.2 ~ 0.4L/min send powder gas flow adjustment range ------- 0 ~ 1L/min shielding gas flow adjustment range -------- 2 ~ 6L/min powder keg powder feeder capacity -------- 5Kg the amount of flour powder feeder sent adjustment range ------- 0 ~ 50g/min --------- 3 ~ 12mm working distance surfacing thickness control: a surfacing thickness ----- ----- about 0.5-4mm width of a surfacing about 2-5mm ---------- ----------- particle size 50-200 mesh powder surfacing efficiency - ---------- ≥ 90% difference, such as multi-ion wood welder and welding ---- power market: the market is currently plasma powder welding machine based mostly power, which to a certain extent the problem is because the plasma power, high-power plasma welding machines are based on both the size of the current power structure dominated welding, low-power boot-dimensional arc welding, TIG power to guide the main arc. So that the host is not easy to carry bulky, thus making the machine is only suitable way to work, not go to work. Victoria arc voltage is too high international standards within the plasma, micro-arc of instability and other reasons, mostly wood plasma welding machine is to overcome the above problems, the use of pure plasma power system is small and light weight for the job at any occasion. Plasma welding gun: the plasma on the market today are mostly external welding gun powder feeding system, the torch handle is also made of ordinary materials, so the process is prone to use, such as blocking powder or leakage, seriously affected the normal production user needs and life safety. Taki plasma welding gun powder feeding system with built-in torch handle polyethylene insulation materials made to overcome the problems. Torch bearer is not enough to meet the current machine reaches full capacity. Powder feeder: the plasma on the market today are surfacing machine scraper feed powder, powder feeding this way for a long time to send pink powder feeding prone to uneven powder blocking phenomenon thereby affecting the normal production needs. Taki plasma welding machine adopts the most advanced impeller send powder, the powder can accurately control the size and speed of delivery and thus to overcome the above problems. Environmental protection and energy saving: currently on the market are mostly plasma welding machine to three-phase power (380v)-based, gas consumption between 4-8 powder utilization at about 70%. (220v) gas consumption and more wood plasma welding machine uses two-phase power between 1-2 powder utilization at about 90%. Thus saving the cost of production. Function: on the market today, plasma welding machine only has a single function (powder cladding), and welding the workpiece bore only surfacing surfacing difficult to do, and more wood plasma welding machine with powder Melting Cover and welding two functions, which for some laughs repair area offers more choices. Relative to the bore welding, the welding gun of 65mm internal bore welding industry has made an indelible contribution. Applications: After the mold before the mold repair repair repair roll after roll before repair after repair front crankshaft crank drill repair repair repair drill the hole before surfacing surfacing XCMG 13122568172
